There are two types of browser plugins, based on the plugin API they
 +
use:
 +
*Netscape plugin API (NPAPI): these plugins work in most smaller browsers ([[Firefox#Plugins|Firefox supports only the Flash Player plugin]], Chromium and Opera do '''not''' support these plugins).
 +
*Pepper plugin API (PPAPI): these plugins work in [[Chromium]] (and Chrome), [[Opera]] and [[Vivaldi]].
 +
 
 +
Most plugins on this page are NPAPI-only, unless noted otherwise.

 +
==== Installation ====
 +
 
 +
The package you will need to install depends on the browser you use.
  
{{Wikipedia|Gnash}}
+
* The NPAPI version can be [[install]]ed with the {{Pkg|flashplugin}} package.
 +
* The PPAPI version can be [[install]]ed with the {{Pkg|pepper-flash}} package.
  
[http://www.gnu.org/software/gnash/ GNU Gnash] is a free (libre) alternative to Adobe Flash Player. It is available both as a standalone player for desktop computers and embedded devices, as well as a browser plugin, and supports the SWF format up to version 7 (with versions 8 and 9 under development) and about 80% of ActionScript 2.0.
+
{{Note|
 +
* Some Flash apps may require the {{AUR|ttf-ms-fonts}} package in order to properly render text.
 +
* The {{AUR|freshplayerplugin}} package provides an ''experimental'' adapter to use {{Pkg|pepper-flash}} with NPAPI based browsers like Firefox. It can be configured (e.g. for enabling HW-acceleration) by copying {{ic|/usr/share/freshplayerplugin/freshwrapper.conf.example}} to {{ic|~/.config/freshwrapper.conf}}.
 +
}}
  
GNU Gnash can be [[Pacman|installed]] with the package {{Pkg|gnash-gtk}}, available in the [[official repositories]].
+
==== Upgrade ====
  
{{Note|If you find that Gnash doesn't work properly right out of the box, then you may also need to [[pacman|install]] {{Pkg|gstreamer0.10-ffmpeg}} from the [[official repositories]].}}
+
If you are using [[Firefox]], please make sure to follow [[Firefox#Firefox detects the wrong version of my plugin|this instruction first]].
  
=== Lightspark ===
+
==== Configuration ====
  
[http://lightspark.github.com/ Lightspark] is another attempt to provide a free alternative to Adobe Flash aimed at supporting newer Flash formats. Although it is still very much in development, it supports some [https://github.com/lightspark/lightspark/wiki/Site-Support popular sites].  
+
To change the preferences (privacy settings, resource usage, etc.) of Flash Player, right click on any embedded Flash content (for instance [https://helpx.adobe.com/flash-player.html adobe's flash home]) and choose ''Settings'' from the menu.
  
Lightspark can be [[Pacman|installed]] with the package {{AUR|lightspark}} or {{AUR|lightspark-git}}, available in the [[AUR]].
+
You can also use the Flash settings file {{ic|/etc/adobe/mms.cfg}}. Gentoo has an extensively commented [http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/www-plugins/adobe-flash/files/mms.cfg example mms.cfg].
  
=== Adobe Flash Player ===
+
To enable video decoding with [[hardware video acceleration]], add/uncomment the following line:
 +
EnableLinuxHWVideoDecode = 1
 +
It might also be required to add/uncomment the following line:
 +
OverrideGPUValidation = 1
  
[[pacman|Install]] {{Pkg|flashplugin}} from the official repositories.

==== Multiple monitor full-screen fix ====
{{Note|
 
* Adobe Flash Player for Linux using the NPAPI was [http://blogs.adobe.com/flashplayer/2012/02/adobe-and-google-partnering-for-flash-player-on-linux.html discontinued by Adobe], although security updates for version 11.2 will be provided for another 5 years by Adobe (i.e. 2017). Adobe will, however, release new versions of PPAPI version of the plugin, shipped with Google Chrome. See [[Chromium#Adobe (Pepper plugin API)]] for more information.
 
* Some versions of Epiphany have trouble recognizing the Flash plugin. See [[Epiphany#Flash|Epiphany]] for more details.
 
* The Adobe Flash Player may also require {{AUR|ttf-ms-fonts}} from the [[AUR]] in order to properly render text.
 
* For hardware acceleration on Intel/AMD, you can use {{AUR|libvdpau-va-gl}} — VAAPI backend for VDPAU. For AMD you should also install {{AUR|xvba-video}}
 
}}
 
  
==== Configuration ====
+
When using a multiple monitor setup, or swapping between virtual desktops, it is possible to lose focus on a fullscreen flash window. In such a case, the adobe flash-plugin will automatically exit full-screen mode. This may not be to your liking.
  
To change the preferences (privacy settings, resource usage, etc.) of Flash Player, right click on any embedded Flash content and choose ''Settings'' from the menu, or go to the [http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager.html Macromedia website]. There, a Flash animation will give you access to your local settings.
+
Unfortunately, this behavior is hard coded into the binary. In order to change this behavior it is necessary to alter the binary.
  
You can also use the Flash settings file {{ic|/etc/adobe/mms.cfg}}. An example configuration:
+
Fixing this issue only works for the NPAPI plugin and this issue can be fixed via 2 ways.
{{hc|/etc/adobe/mms.cfg|<nowiki>

=== Shumway ===
  
Install {{Pkg|devilspie}} from the official repositories.
+
[http://mozilla.github.io/shumway/ Shumway] is a [https://github.com/mozilla/shumway/issues/2420 discontinued] HTML5 technology experiment that explores building a faithful and efficient renderer for the SWF file format without native code assistance. The plugin may be installed directly from [http://mozilla.github.io/shumway/ Mozilla's github.io site].
  
Create the {{ic|~/.devilspie}} directory and the relevant config:
+
=== Gnash ===
  
# mkdir ~/.devilspie
+
[[Wikipedia:Gnash (software)|Gnash]] is a free (libre) alternative to Adobe Flash Player. It is available both as a standalone player for desktop computers and embedded devices, as well as a browser plugin, and supports the SWF format up to version 7 (with versions 8 and 9 under development) and about 80% of ActionScript 2.0.
# touch ~/.devilspie/flash-fullscreen-firefox.ds

Finally, add devilspie to your list of startup items (usually in gnome-session-properties).  
+
[http://lightspark.github.com/ Lightspark] is another attempt to provide a free alternative to Adobe Flash aimed at supporting newer Flash formats. Lightspark has the ability to fall back on Gnash for old content, which enables users to install both and enjoy wider coverage. Although it is still very much in development, it supports some [https://github.com/lightspark/lightspark/wiki/Site-Support popular sites].  
  
For this to work in Chrome / Chromium, {{ic|"plugin-container"}} needs to be replaced by {{ic|"exe"}} in the script above.
+
Lightspark can be [[install]]ed with the {{AUR|lightspark-git}} package.

=== Adobe Reader ===
+
== Online payment in China ==
  
Due to licensing restrictions, Adobe Reader cannot be distributed from any of the official Arch Linux repositories. There are versions available in the [[AUR]]. Please note that no matter how many votes it receives, Adobe Reader will never be included in the [[official repositories]].
+
Third-party online payment sites in China tend to use a "security plugin" for the password field.
 +
They are not supported anymore in Firefox 52+. You could try {{AUR|palemoon}} for NPAPI support.
 +
* {{AUR|upeditor}} for UnionPay Online Pay (银联在线支付).
  
Also, there are [https://aur.archlinux.org/packages.php?O=0&K=acroread-&do_Search=Go localizations] available in many languages.
+
== Citrix ==
  
==== 32-bit ====
+
See [[Citrix]].
  
Adobe Acrobat Reader is only available as a 32-bit binary. It can be installed with the {{AUR|acroread}} package, available in the [[AUR]].
+
== Java (IcedTea) ==
 
 
This package installs the Acrobat Reader application as well as the Firefox plugin. Note that hardware-assisted rendering is unavailable under Linux (at least using a Geforce 8600GTS with driver version 185.18.14).
 
 
 
==== 64-bit ====
 
 
 
There is yet to be an official 64-bit version of Adobe Reader.
 
 
 
To use it in a 64-bit environment, you can:
 
* Follow [[Install bundled 32-bit system in Arch64|this guide]] originally posted in the forums. It involves creating a chrooted environment that could be reused for other 32-bit only applications.
 
  
* Install {{AUR|acroread}} (with all its 32-bit dependencies) from [[AUR]]. Be advised that the [[Firefox]] plugin cannot be used ''directly'' with this binary -- it will not load in the 64-bit browser. To load it install the {{Pkg|nspluginwrapper}} package from the official [[Multilib|[multilib]]] repository and run:
+
{{Note|Both Java plugins are NPAPI-only and thus do not work in Chromium, Opera and Firefox [https://support.mozilla.org/t5/Problems-with-add-ons-plugins-or/Why-do-Java-Silverlight-Adobe-Acrobat-and-other-plugins-no/ta-p/31069 52 and newer].

Many browsers support the [[GStreamer]] framework to play multimedia inside HTML5 {{ic|<audio>}} and {{ic|<video>}} elements. Check the optional dependencies of the browser package (or of the web engine, e.g. {{Pkg|webkit2gtk}} or {{Pkg|qt5-webkit}}) to see if GStreamer is supported. See [[GStreamer#Installation]] for the description of each plugin.
  
== Video plugins ==
+
For media formats that are not natively supported by your browser (e.g. most browsers don't play {{ic|.mkv}} files), the following plugins are available:
  
* {{App|Gecko Media Player|Mozilla browser plugin to handle media on websites, using MPlayer.|https://sites.google.com/site/kdekorte2/gecko-mediaplayer|{{Pkg|gecko-mediaplayer}}}}
 
* {{App|Totem Plugin|Browser plugin based on the [[Wikipedia:Totem (software)|Totem]] media player for [[Gnome]] which uses [[Gstreamer]].|http://projects.gnome.org/totem/|{{Pkg|totem-plugin}}}}

Version 0.5 of {{Pkg|libvdpau}} includes a workaround to fix this, see the [http://lists.x.org/archives/xorg-announce/2012-September/002066.html official announcement].
 
  
=== Flash Player: leaking overlay with NVIDIA ===
+
Solution for Firefox: delete file "pluginreg.dat" in user's profile directory.
  
This bug is due to the incorrect color key being used by the {{Pkg|flashplugin}} version 11.2.202.228-1 (see [http://www.nvnews.net/vbulletin/showpost.php?p=2514210&postcount=102 this post] on the NVIDIA forums) and causes the Flash content to "leak" into other pages or solid black backgrounds. To avoid this issue simply export {{ic|1=VDPAU_NVIDIA_NO_OVERLAY=1}} within either your shell profile (e.g. {{ic|~/.bash_profile}} or {{ic|~/.zprofile}}) or {{ic|~/.xinitrc}}
+
* Close firefox
 +
* Go to {{ic|/home/''<username>''/.mozilla/firefox/''<profile_folder>''/}}
 +
* Delete file "pluginreg.dat"
  
=== Flash Player: videos not working on older systems ===
+
Firefox will automatically rebuild this file once it is started again. Make sure to substitute ''<username>'' and ''<profile_folder>'' with the appropriate information.
  
If you have Adobe Flash installed on an older system and you start playing a video which simply turns black with nothing happening, it is most likely that your CPU does not support SSE2. You can simply check this by looking at your CPU flags with this command:
+
=== Firefox: plugins are installed but not working ===
$ grep sse2 /proc/cpuinfo
 
 
 
If no results are returned, then you need to install an older version of Flash (for example 10.3, or 11.1). Older versions possibly will have vulnerabilities. You should then consider sandboxing Firefox using {{AUR|sandfox}}, available in the [[AUR]]. See the [https://igurublog.wordpress.com/downloads/script-sandfox/ sandfox homepage] for usage information.
 
 
 
Older versions of Flash are available here:
 
http://www.adobe.com/products/flashplayer/distribution3.html
 
You need to copy {{ic|libflashplayer.so}} to the folder {{ic|/usr/lib/mozilla/plugins/}}
 
 
 
Older {{Pkg|flashplugin}} packages can be downloaded from the [[AUR]] e.g. {{AUR|flashplugin-nosse2}}. Alternatively you can install {{AUR|flashplugin-sse2-nosse2}} which can be used on CPUs with and without SSE2.
 
 
 
The most recent package without SSE2 is {{ic|flashplugin-11.1.102.63-1-i686.pkg.tar.xz}}. If you use the packaged version, you have to add {{ic|IgnorePkg &#61; flashplugin}} to {{ic|/etc/pacman.conf}}.
 
 
 
=== Plugins are installed but not working ===
 
  
 
A common problem is that the plugin path is unset. This typically occurs on a new install, when the user has not re-logged in before running Firefox after the installation. Test if the path is unset:

There are two types of browser plugins, based on the plugin API they use:

Most plugins on this page are NPAPI-only, unless noted otherwise.

Flash Player

Adobe Flash Player

Installation

The package you will need to install depends on the browser you use.

Note:
  • Some Flash apps may require the ttf-ms-fontsAUR package in order to properly render text.
  • The freshplayerpluginAUR package provides an experimental adapter to use pepper-flash with NPAPI based browsers like Firefox. It can be configured (e.g. for enabling HW-acceleration) by copying /usr/share/freshplayerplugin/freshwrapper.conf.example to ~/.config/freshwrapper.conf.

Upgrade

If you are using Firefox, please make sure to follow this instruction first.

Configuration

To change the preferences (privacy settings, resource usage, etc.) of Flash Player, right click on any embedded Flash content (for instance adobe's flash home) and choose Settings from the menu.

You can also use the Flash settings file /etc/adobe/mms.cfg. Gentoo has an extensively commented example mms.cfg.

To enable video decoding with hardware video acceleration, add/uncomment the following line:

EnableLinuxHWVideoDecode = 1

It might also be required to add/uncomment the following line:

OverrideGPUValidation = 1

Multiple monitor full-screen fix

When using a multiple monitor setup, or swapping between virtual desktops, it is possible to lose focus on a fullscreen flash window. In such a case, the adobe flash-plugin will automatically exit full-screen mode. This may not be to your liking.

Unfortunately, this behavior is hard coded into the binary. In order to change this behavior it is necessary to alter the binary.

Fixing this issue only works for the NPAPI plugin and this issue can be fixed via 2 ways.

After the package has been installed, backup libflashplayer.so:
# cp /usr/lib/mozilla/plugins/libflashplayer.so /usr/lib/mozilla/plugins/libflashplayer.so.backup
Then, you will need to alter that file using a hex editor like ghex. You must open it with root privileges obviously.
# ghex /usr/lib/mozilla/plugins/libflashplayer.so
Using the hex editor find the string _NET_ACTIVE_WINDOW. In ghex the readable string is on the right hand side of the window, and the hex is on the left, you are trying to locate the readable string. It should be easy to find using a search function.
Upon finding _NET_ACTIVE_WINDOW rewrite the line, but do not change the length of the line, for example _NET_ACTIVE_WINDOW becomes _XET_ACTIVE_WINDOW.
Save the binary, and restart any processes using the plugin (as this will crash any instance of the plugin in use.)

Playing DRM-protected content

See Flash DRM content.

Shumway

Shumway is a discontinued HTML5 technology experiment that explores building a faithful and efficient renderer for the SWF file format without native code assistance. The plugin may be installed directly from Mozilla's github.io site.

Gnash

Gnash is a free (libre) alternative to Adobe Flash Player. It is available both as a standalone player for desktop computers and embedded devices, as well as a browser plugin, and supports the SWF format up to version 7 (with versions 8 and 9 under development) and about 80% of ActionScript 2.0.

There is a packages available: gnash-gitAUR.

Lightspark

Lightspark is another attempt to provide a free alternative to Adobe Flash aimed at supporting newer Flash formats. Lightspark has the ability to fall back on Gnash for old content, which enables users to install both and enjoy wider coverage. Although it is still very much in development, it supports some popular sites.

Lightspark can be installed with the lightspark-gitAUR package.

PDF viewer

PDF.js

PDF.js is a PDF renderer created by Mozilla and built using HTML5 technologies.

It is included in Firefox.

For Chromium and Google Chrome it is available as extension in the Chrome Web Store.

External PDF viewers

To use an external PDF viewer you need #MozPlugger.

If you want to use MozPlugger with Evince, for example, you have to find the lines containing pdf in the /etc/mozpluggerrc file and modify the corresponding line after GV() as below:

repeat noisy swallow(evince) fill: evince "$file"

(replace evince with something else if it is not your viewer of choice).

When using Firefox, you may need to change 2 values in about:config:

  • Change pdfjs.disabled's value to true;
  • Change plugin.disable_full_page_plugin_for_types's value to an empty value.

Restart and it should work like a charm!

Online payment in China

Third-party online payment sites in China tend to use a "security plugin" for the password field. They are not supported anymore in Firefox 52+. You could try palemoonAUR for NPAPI support.

  • upeditorAUR for UnionPay Online Pay (银联在线支付).

Citrix

See Citrix.

Java (IcedTea)

Note: Both Java plugins are NPAPI-only and thus do not work in Chromium, Opera and Firefox 52 and newer. Firefox ESR will continue supporting NPAPI plugins until early 2018.

To enable Java support in your browser, you have two options: the open-source OpenJDK (recommended) or Oracle's proprietary version. For details about why OpenJDK is recommended see [1].

To use OpenJDK, you have to install the IcedTea browser plugin, icedtea-web.

If you want to use Oracle's JRE, install the jreAUR package.

Note: If you experience any problems with the Java plugin (e.g. it is not recognized by the browser), you can try #Firefox: plugins are installed but not working.

Pipelight

See Pipelight.

Multimedia playback

Many browsers support the GStreamer framework to play multimedia inside HTML5 <audio> and <video> elements. Check the optional dependencies of the browser package (or of the web engine, e.g. webkit2gtk or qt5-webkit) to see if GStreamer is supported. See GStreamer#Installation for the description of each plugin.

For media formats that are not natively supported by your browser (e.g. most browsers don't play .mkv files), the following plugins are available:

  • Rosa Media Player Plugin — Qt-based browser plugin also based on MPlayer.
https://abf.rosalinux.ru/uxteam/ROSA_Media_Player || rosa-media-player-pluginAUR
  • VLC Plugin — NPAPI-based plugin that uses VLC technologies.
https://code.videolan.org/videolan/npapi-vlc || npapi-vlc

Google Hangouts

Note:
  • This plugin is not required when using Chromium
  • Hangouts calling doesn't work in Firefox as of March 2017.[2][3]

Hangouts plugin can be installed with the google-talkpluginAUR package. Hangouts is a messenger by Google, that allows you to make video call between 15 people simultaneously, or share your screen with others.

MozPlugger

MozPlugger can be installed with the mozpluggerAUR package.

MozPlugger is a Mozilla plugin which can show many types of multimedia inside your browser. To accomplish this, it uses external programs such as MPlayer, xine, Evince, OpenOffice, TiMidity, etc. To modify or add applications to be used by MozPlugger just modify the /etc/mozpluggerrc file.

For example, MozPlugger uses OpenOffice by default to open doc files. To change it to use LibreOffice instead, look for the OpenOffice section:

/etc/mozpluggerrc
...
### OpenOffice
define([OO],[swallow(VCLSalFrame) fill: ooffice2.0 -nologo -norestore -view $1 "$file"
    swallow(VCLSalFrame) fill: ooffice -nologo -norestore -view $1 "$file"
    swallow(VCLSalFrame) fill: soffice -nologo $1 "$file"])
...

and add LibreOffice at the beginning of the list:

/etc/mozpluggerrc
...
### LibreOffice/OpenOffice
define([OO],[swallow(VCLSalFrame) fill: libreoffice --nologo --norestore --view $1 "$file"
    swallow(VCLSalFrame) fill: ooffice2.0 -nologo -norestore -view $1 "$file"
    swallow(VCLSalFrame) fill: ooffice -nologo -norestore -view $1 "$file"
    swallow(VCLSalFrame) fill: soffice -nologo $1 "$file"])
...
Note: Be sure to also choose LibreOffice as your preferred application to open doc files.

As another simple example, if you want to open cpp files with your favorite text editor (we will use Kate) to get syntax highlighting, just add a new section to your mozpluggerrc file:

/etc/mozpluggerrc
text/x-c++:cpp:C++ Source File
text/x-c++:hpp:C++ Header File
    repeat noisy swallow(kate) fill: kate -b "$file"

To change the default of MPlayer so that mpv is used instead, change the appropriate lines such that:

/etc/mozpluggerrc
...
### MPlayer

#define(MP_CMD,[mplayer -really-quiet -nojoystick -nofs -zoom -vo xv,x11 -ao esd,alsa,oss,arts,null -osdlevel 0 $1 </dev/null])
define(MP_CMD,[mpv -really-quiet $1 </dev/null])

#define(MP_EMBED,[embed noisy ignore_errors: MP_CMD(-xy $width -wid $window $1)])
define(MP_EMBED,[embed noisy ignore_errors: MP_CMD(--autofit=$width -wid $window $1)])

#define(MP_NOEMBED,[noembed noisy ignore_errors maxaspect swallow(MPlayer): MP_CMD($1)])
define(MP_NOEMBED,[noembed noisy ignore_errors maxaspect swallow(mpv): MP_CMD($1)])

...

#define(MP_AUDIO,[mplayer -quiet -nojoystick $1 </dev/null])
define(MP_AUDIO,[mpv -really-quiet $1 </dev/null])

#define(MP_AUDIO_STREAM,[controls stream noisy ignore_errors: mplayer -quiet -nojoystick $1 "$file" </dev/null])
define(MP_AUDIO_STREAM,[controls stream noisy ignore_errors: mpv -really-quiet $1 "$file" </dev/null])
...

For a more complete list of MozPlugger options see mozplugger(7).

Troubleshooting

Flash Player: no sound

Flash Player outputs its sound only through the default ALSA device, which is number 0. If you have multiple sound devices (a very common example is having a sound card and HDMI output in the video card), then your preferred device may have a different number.

For a list of available devices with their respective numbers, run:

$ aplay -l
 **** List of PLAYBACK Hardware Devices ****
 card 0: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
   Subdevices: 1/1
   Subdevice #0: subdevice #0
 card 1: DX [Xonar DX], device 0: Multichannel [Multichannel]
   Subdevices: 0/1
   Subdevice #0: subdevice #0
 card 1: DX [Xonar DX], device 1: Digital [Digital]
   Subdevices: 1/1
   Subdevice #0: subdevice #0

In this case, the HDMI output is card 0 and the sound card is card 1. To make your sound card the default for ALSA, create the file .asoundrc in your home directory, with the following content:

~/.asoundrc
pcm.!default {
    type hw
    card 1
}
 
ctl.!default {
    type hw
    card 1
}

Flash Player: blocking sound for other applications or delayed playback

If sound is delayed within Flash videos or Flash stops sound from any other application, then make sure you do not have snd_pcm_oss module loaded:

$ lsmod | grep snd_pcm_oss

You can unload it:

# rmmod snd_pcm_oss

and restart the browser to see if it helps.

Flash Player: performance

Adobe's Flash plugin has some serious performance issues, especially when CPU frequency scaling is used. There seems to be a policy not to use the whole CPU workload, so the frequency scaling governor does not clock the CPU any higher. To work around this issue, see CPU frequency scaling#Switching threshold

Flash Player: no webcam, or low webcam resolution

If Flash doesn't detect your webcam at all, or it has low resolution (the image looks very pixelated), you can try starting your browser with this:

$ LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so <browser>

This is because Flash still uses the V4L1 camera API, long deprecated, and via the above we give it a compatibility layer which it needs.

Flash Player: black bars in full screen playback on multi-headed setups

The Flash plugin has a known bug where the full screen mode does not really work when you have a multi-monitor setup. Apparently, it incorrectly determines the full screen resolution, so the full screen Flash Player fills the correct monitor but gets scaled as if the monitor had the resolution of the total display area.

To fix this, you can use the "hack" described here. Simply download the source from the link given on the page, and follow the instructions in the README.

Note: While the author mentions using NVDIA's TwinView, the hack should work for any multi-monitor setup.

Firefox: old Flash Player version shown after upgrade

Solution for Firefox: delete file "pluginreg.dat" in user's profile directory.

  • Close firefox
  • Go to /home/<username>/.mozilla/firefox/<profile_folder>/
  • Delete file "pluginreg.dat"

Firefox will automatically rebuild this file once it is started again. Make sure to substitute <username> and <profile_folder> with the appropriate information.

Firefox: plugins are installed but not working

A common problem is that the plugin path is unset. This typically occurs on a new install, when the user has not re-logged in before running Firefox after the installation. Test if the path is unset:

$ printenv MOZ_PLUGIN_PATH

If unset, then either re-login, or source /etc/profile.d/mozilla-common.sh and start Firefox from the same shell:

$ source /etc/profile.d/mozilla-common.sh && firefox
