Reason: This information may not be representative of the state of Opera. Some options presented in this article cannot be accessed in the ways described. (Discuss in Talk:Opera)

Opera is a free of charge web browser developed since 1994 by the Norwegian company Opera Software. It is known for being the first to bring new browsing features to the world that have become common on all web browsers, such as tabbed browsing and built-in search.


Install the opera package.


For details about different plugins and installation instructions see Browser plugins. Note that Opera no longer supports the Netscape plugin API (NPAPI), but only the newer Pepper plugin API (PPAPI).


Tip: Opera also has a built-in ad blocker which can be enabled in Settings.

Install Adblock support using the opera-adblock-completeAUR package.

Performance tweaks

Although Opera is fast on modern hardware, it can be made even faster.

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.

Some commonly disabled features are:

  • Systray Icon: uncheck Show Tray Icon under opera:config#UserPrefs.
  • BitTorrent: uncheck Enable under opera:config#BitTorrent.
  • Geolocation: uncheck Enable geolocation under opera:config#Geolocation.
  • Multimedia: unckeck desired options under opera:config#Multimedia.
  • Web Server: uncheck Enable under opera:config#Web Server.

To more easily find these options just write the respective path (without spaces) in the address bar, for example opera:config#UserPrefs|ShowTrayIcon or use the built-in search.

Profile in tmpfs

Relocate the browser profile to a tmpfs filesystem, including /tmp for improvements in application response as 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.

There are currently two ways of doing this:

  • using Profile-sync-daemon, that automatically detects and relocates the Opera profile to tmpfs.
  • using the -pd command-line flag to tell Opera where to store its profile data:
$ opera -pd /tmp/opera



Although Opera is cross-platform, it can be made to integrate very well into various Linux desktop environments.

To make the menus look integrated with Qt, install your preferred Qt theme and apply it by using qtconfig.
To make Opera use KDE icons, you can install a theme such as this one.
A nice GTK skin that uses the Tango icon theme can be found here.

Title bar

The title bar can be hidden by right-clicking on the tab bar, then unchecking "Show Border".

Tab modes

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 Menu > Appearance > Buttons > Browser.


Fonts can be configured under Settings > Preferences... > Advanced > Fonts.

If the ttf-ms-fontsAUR package 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 system:

  • 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.
Note: If no text except numbers is showing on some of the webpages that might be a problem with the fonts. A known issue that causes this problem is the helvetica pfb postscript fonts.

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 Private Browsing in Firefox.

To open a private tab from the command-line use:

$ opera --private

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.

To open a new window for private browsing when already running Opera you can just press Ctrl+Shift+N or look under Menu > New Tabs and Windows > New Private Window. All subsequent opened tabs with be private as well.

Accessibility Tips

Disable text selection

It is possible to disable text selection in Opera. However, text selection through JavaScript will still work (for example 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 into a toolbar. The button can be found in Menu > Appearance > 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.

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.


Force a password store

Since current Opera uses the same engine as Chromium does, you can force Opera to use a specific password store by launching it with the --password-store flag. For more details see Chromium/Tips and tricks#Force a password store.


Slow scrolling on NVIDIA cards

Try running the following command:

$ nvidia-settings -a InitialPixmapPlacement=2

On some computers, https://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

If Opera does not display a site well, 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 GTK 2.24.7+

If this crash occurs, you can work around it by changing the DialogToolkit option to 4:


This will disable GTK styling support and hence avoid the issue.

Unreadable input fields and address bar with dark GTK themes

When using a dark GTK theme, one might encounter Opera address bar and Internet pages with unreadable input and text fields (e.g. Amazon can have black text on black text field background). This can happen because the site only sets either background or text color, and Opera takes the other one from the theme.

Using an installed clear theme and a command help to work around the problem: env GTK_THEME=<light-theme-name> opera

to turn it as default, edit the file /usr/bin/opera and replace the line with exec /usr/lib/opera/opera "$@". e.g. using Opera 12.14:

export OPERA_DIR=${OPERA_DIR:-/usr/share/opera}
env GTK_THEME=Clearlooks /usr/lib/opera/opera "$@"

this will make the browser use a clear theme that you set in the file /usr/bin/opera that was used in the above example the theme "Clearlooks" and the problems will be solved.
