Opera is a web browser and Internet suite developed by Opera Software. The browser handles common Internet-related tasks such as displaying websites, sending and receiving e-mail messages, managing contacts, IRC online chatting, downloading files via BitTorrent, and reading web feeds.[1] Opera consumes approximately 36 MB installed on disk and is built for speed, incorporating numerous options and shortcuts to simply web tasks. :[1] "Opera_(web_browser)". Wikipedia. 19 Sep. 2010. Wikimedia Foundation, Inc. 22 Sep. 2010 <http://en.wikipedia.org/wiki/Opera_(web_browser)>.


The opera package can be found in the official repositories.


Opera can use Mozilla-based plugins; see Browser Plugins for details. The plugin path can be specified under Settings > Preferences > Advanced > Content > Plug-in Options

64-bit Flash

Install the flashplugin package from the official repositories.

Performance tweaks

Disabling features and services

One of the keys to maximizing application performance is to disable undesired features and services through the native opera:config Preferences Editor.

  • Start Opera without the default system tray icon by unchecking the following option:
opera:config#UserPrefs | ShowTrayIcon

Other commonly disabled feature sets include but are not limited to:

Additional command-line options are available for further control over browser features and services:

  • Start Opera without the default internal e-mail client
$ opera -nomail
  • Alternatively, if you want to permanently disable the internal e-mail client without using "-nomail", you can uncheck the setting "Show E-mail Client" in opera:config
  • Start Opera without an ARGB (32-bit) visual, without LIRC infrared control support and mailto: links disabled:
$ opera -noargb -nolirc -nomaillinks
  • Start Opera without the internal BitTorrent downloader: uncheck "Enable" under the BitTorrent section in opera:config

Improving Flash performance

  • Set the following environment variables before starting Opera, or export the entries in xinitrc, or .bash_profile, or for system-wide changes, to /etc/profile:

xinitrc example

/usr/bin/urxvtd -q -f -o &
exec ck-launch-session /usr/bin/jwm

Command-line example

  • Another environment variable which may help resolve Flash issues:

See the blog article Flash problems on Linux? for additional details.

Profile in tmpfs

Relocate the browser profile to tmpfs filesystem, including /tmp for improvements in application response as the the entire profile is now stored in RAM. Another benefit is a reduction in disk read and write operations, of which SSDs benefit the most.

Opera and Opera-beta

Use an active management script for maximal reliability and ease of use.

Refer to the Profile-sync-daemon wiki article for additional info on it.


In the case of opera-next, launch Opera with the -pd option to set the location of the alternative Opera preferences folder:

$ opera -pd /tmp/.opera

Any number of command-line options may be included in the string:

$ opera -newprivatetab -noargb -nolirc -nomail -nomaillinks -pd /tmp/.opera

Microsoft fonts and Opera

Configure fonts under Settings > Preferences > Advanced > Fonts. If ttf-ms-fontsAUR has been installed before running Opera for the first time, Opera will use those fonts by default, regardless of what is specified by local GTK options, GNOME, or KDE font management. To force existing installations of Opera to use the options set by your font manager:

  • Close all running instances of Opera.
  • Un-install the ttf-ms-fontsAUR package.
  • Move the existing profile folder: mv -i ~/.opera ~/.opera.bak
  • Run an instance of Opera and verify that your font manager settings have been applied.
  • Restore bookmarks and desired filter files from ~/.opera.bak to ~/.opera except for the operaprefs.ini file.
  • Re-install the ttf-ms-fontsAUR package, if desired.

UI appearance

  • To make the menus look integrated with Qt, install your preferred Qt4 theme and apply it by using qtconfig.
  • To make Opera use KDE icons, download a native skin such as fixed_window_skin
  • A nice gtk2 skin with tango icon theme can be found here. Integrates very well with Xfce4 and other gtk2 environments.
  • Opera has native support for tab cascading and tiling mode. Appropriate buttons can be found by activating the "main" toolbar or by dragging and dropping the buttons anywhere desired, found in appearance (Template:Keypress) -> buttons -> browser.

Private tabs

To browse without leaving obvious traces of the Web sites you visit, you can use a private tab. When you close a private tab, the following data related to the tab is deleted:

  • Cache
  • Cookies
  • History
  • Logins

This is similar to the --incognito option in Chrome/Chromium and PrivateBrowsing in Firefox.

  • Open the URL (if a URL is defined) in Opera with a private tab.
$ opera -newprivatetab

To ensure only private tabs are used throughout the duration of the browsing session:

  • Set Settings > Preferences... > General > Startup > Start without open tabs
  • Clear any entries in Settings > Preferences... > General > Home page option
  • Enable Settings > Preferences... > Advanced > Tabs > Additional tab options... > Allow windows with no tabs

Java Support

Note: Oracle's proprietary version of the JRE has been pulled from the [community] repository. Read here for more information.
Note: If you want to use Java version 7, use the packages jre7-openjdk and icedtea-web-java7 instead.

See Java#OpenJDK_JVM for additional details and references.

Accessibility Tips

Disable text selection

It is also possible to disable text selection. However, text selection through javascript will still work (ex. in forms etc.). To get to the setting follow the link bellow


Grab and scroll mode

Besides setting text selection off, grab and scroll mode makes page scrolling possible with mouse dragging. It is very useful, especially when you have a touchscreen. Copy and paste the link bellow to get to the mentioned setting.


It is also possible to change this setting on the fly by dragging and dropping the appropriate Opera button anywhere desired, found in appearance (Template:Keypress) -> buttons -> browser view.

Long pressing a link opens it in a background tab (extension)

It is possible to open up any long-clicked link in a new background tab by installing this extension from myopera community.

Virtual On-Screen keyboard (extension)

There is an extension which allows the use of an on-screen virtual keyboard. Further details and installation link can be found here.


Java on Arch64

Tango-inaccurate.pngThe factual accuracy of this article or section is disputed.Tango-inaccurate.png

Reason: please use the first argument of the template to provide a brief explanation. (Discuss in Talk:Opera#)

1. Add to ~/.bash_profile, or /etc/profile to make this setting affect all logins:

# openjdk
export LD_LIBRARY_PATH=/usr/lib/jvm/java-6-openjdk/jre/lib/amd64/server/
# jre
export LD_LIBRARY_PATH=/opt/java/jre/lib/amd64/server/

Alternatively, create a symlink to libjvm.so:

# openjdk
cd /usr/lib/jvm/java-6-openjdk/jre/lib/amd64
ln -s server/libjvm.so .
# jre
cd /opt/java/jre/lib/amd64
ln -s server/libjvm.so .

2. Edit the path to Java in Opera: Menu -> Tools -> Preferences -> Advanced -> Content -> Plugin-Options.


Slow scrolling on NVIDIA cards

Try running the following command:

$ nvidia-settings -a InitialPixmapPlacement=2

On some computers, http://helion.pl works extremely slow without this hack, making it a perfect site for testing.

Horizontal mouse wheel scrolling

Check Settings > Preferences > Advanced > Shortcuts > Mouse > Middle-Click Options... > Enable horizontal panning


  • Highlight Settings > Preferences > Advanced > Shortcuts > Mouse > Opera Standard
  • Duplicate Settings > Preferences > Advanced > Shortcuts > Mouse > Opera Standard
  • Edit... Settings > Preferences > Advanced > Shortcuts > Mouse > Copy of Opera Standard
  • Search the Forward and Back input contexts and edit the appropriate button shortcuts to scroll left and scroll right
  • Rename Settings > Preferences > Advanced > Shortcuts > Mouse > Copy of Opera Standard as desired

Launching an external browser

Opera does not display sites well at times. A workaround is to launch the currently displayed page in an external browser.

Note: The following method appears to be deprecated in favor of the built-in Open With menu accessed via the right mouse button.
  • Set the following line under [Site Navigation Toolbar.content] in $HOME/.opera/toolbar/standard_toolbar.ini:
Button0, "Chromium"="Execute program, "chromium, "%u", , "Chromium""
  • If Firefox is desired, or preferred:
Button0, "Firefox"="Execute program, "firefox", "%u", , "Firefox""
  • Any number of command-line options may be included in the string:
Button0, "Chromium"="Execute program, "chromium --block-nonsandboxed-plugins --disable-java --incognito --safe-plugins --start-maximized --user-data-dir=/tmp/.chromium", "%u", , "Chromium""

Opera crashes when starting or closing with gtk2 2.24.7+

You can work around this for now by changing the DialogToolkit option to 4:


This will disable Gtk styling support and hence avoid the issue. It will probably be fixed in the next Opera release (11.60+).
