I-Firefox Isithangami Sokwesekwa

When visiting sites such as the Russian Wikipedia, characters that are in the Cyrillic Times New Roman font display as blocks (shown in image). Safari does not have this problem.

Please let me know how I can get my old bookmarks as I do not have any on file in the restore area the only ones I have are five teen year old ones, Can you please help me restore them to the my original ones?

Ive been using FireFox for a while and think its great but FireFox suddenly stopped working for me even though I use it everyday just fine. The search bar works but literally nothing else works. Its very annoying and I do not know what to do. Someone please help me fix it. I use windows 11 on a HP computer, I do have a lot of extensions but absolutely nothing works so I cant check. Nothing I try will work. I cant list the extensions I have because it’s completely blank and glitched. I hope it isn’t a severe problem. Please give me some advice!

I made the mistake to sign into my Firefox account at work and all my personal bookmarks got replaced by my work bookmarks. now when i sign in into my account at my house, i can only see my work bookmarks. how do i recover my personal bookmarks? thank you
