Romanian Language Pack
Romanian Language Pack is a Firefox extension that translates the Firefox interface into the Romanian language. It is quite easy to install and set up.
All you have to do type in "about:config" in the address bar, along with "locale" in the search box, locate the "general.useragent.locale" preference name and modify its value to "ro" from the right-click menu. It is required to restart the web browser, in order to apply the new settings.
From this point on, all of Firefox's menus and buttons are translated into the Romanian language. If you change your mind about the new setting, it is possible to revert it to default by following the same steps.
Romanian Language Pack does not burden Firefox's overall performance or make it unstable. It perfectly integrated into the web browser and didn't cause it to hang, crash or pop up error messages throughout our evaluation.
Unfortunately, the add-on has not been updated for a long time and it does not work with newer Firefox editions. Other than that, Romanian Language Pack comes in handy to all Romanian users who frequently navigate webpages through this browser.
