Changing the language in FirefoxFabian Piau | Saturday October 1st, 2011 - 04:24 PM
To change the language of Firefox, you can reinstall it by choosing the language of your choice on the official page. But there is far better!
Maybe your favourite browser is not in your own language or you want simply to change it. You can reinstall Firefox and select the package with the language you want. But this is not the best way.
This method can help you change any language from one to another in few seconds, like if you were just adding an extension.
Install the language of your choice
- Firefox 25.0.1 in french : http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/25.0.1/linux-i686/xpi/fr.xpi
- Firefox 25.0.1 in spanish : http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/25.0.1/linux-i686/xpi/es-ES.xpi
- Firefox 25.0.1 in english (United States) : http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/25.0.1/linux-i686/xpi/en-US.xpi
- Firefox 25.0.1 in english (Great Britain) : http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/25.0.1/linux-i686/xpi/en-GB.xpi
If you want another language or you are using a different version, go to the Mozilla Firefox’s FTP website : http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/
Navigate in folders by choosing your current version and select “linux-i686” even if it is not your operating system.
Then, select the “xpi” folder within it.
You may need to know the abbreviation of your desired language. If you see multiple xpi results for your preferred language, identify the abbreviation of your region (see examples above).
Select the xpi file that corresponds to the language you want to install.
Click “Authorize” and “Install now”.
Select your new language
about:config” in the address bar and change the value of “
general.useragent.locale” with the abbreviation of your new language (“
You need to restart Firefox to see that the language has been changed !
