Is it just the webpage or Firefox menus also? If just the webpage, that may be a website issue.

This happened in Google search (check the example I attached!) This happens ONLY in FireFox (not in Chrome) and only on a particular computer on which I use the same accounts. To be on the safe side, I checked my Google account settings and there too the only language is English, not Arabic.

So this is still unsolved.

Did you try Google Search settings > languages - as opposed to your Google Account settings?

Hello   tamar.friedlander,

Please, try to start Firefox with the -purgecaches command line switch   -   see the last comment in this bug report :

https://bugzilla.mozilla.org/show_bug.cgi?id=1564998

Try to add the full path to the Firefox installation folder :

• "C:\Program Files\Mozilla Firefox\firefox.exe" -purgecaches • (64-bit Firefox) "C:\Program Files\Mozilla Firefox\" • (32-bit Firefox) "C:\Program Files (x86)\Mozilla Firefox\"

Also see : https://developer.mozilla.org/en-US/Command_Line_Options

Any difference ?

When I posted the above,   "fade2gray's"   post hadn't shown up yet,
due to the spam filtering.

Thanks.

This was indeed in the google search settings.
