Форум поддержки Firefox

I have a Brand New Win 10 Desktop Computer. My old computer had Firefox, I signed in and ran a sync.

Now on the New Computer I sign in and it syncs and transfers all my stuff over. However! alot of sites i browse are going in to German, - .de (like YouTube or Dell).

I have download the latest Firefox (GB/UK English) Version. I have checked all location settings/Time etc & all set to UK. I do not have VPN add in or anything.

MS Edge Browser on the New Computer is Working Fine no German sites.

Please Help.

Hebrew doesn't display in the Firefox search box or in the title of tabs. But when I type in the Firefox search box and hit enter, it performs the search and the writing displays correctly in the Google search box in the Google results page. Firefox is the latest version. Mac is OS X 10.6.8. I see that Microchip470 posted the exact same problem.

I'm having this strange problem where most of my Firefox is in English, but the add-ons and any content related to them I see are all in Italian. It started when prior to a holiday, I was studying Italian, and I was trying to set all of my programs in Italian to try and immerse myself, and I can't remember what I did, but I managed to only make the add-ons switch to Italian, but now that my holiday's over, the add-ons are stuck on the language, and even uninstalling and reinstalling didn't fix it!

What do I do?
