Firefox — Fora społeczności

Hello. I have a problem with the chat.deepseek.com website - every time I launch the browser, the language settings are reset from the system (or Russian) language set manually to English. Interestingly, this problem only occurs in Firefox, while other browsers work as expected. Additionally, the test profile created again also works properly. What I have done: 1. Reinstalled the browser, but it did not help 2. Deleted the folders responsible for Local Storage in the profile folder - didn't help 3. Cleared the cookies - helped until the first restart, then it was the same. History is enabled, and cookies are not cleared when the browser is closed. How can I solve this issue without deleting my profile? I don't want to lose my bookmarks, passwords, and website settings. Thank you in advance for your assistance.

the website gem.cbc.ca no longer allows me to play a video in Firefox since Monday this week, but works as usual on Chrome. I have the same add-ons on both browsers Adblock+ and NoScript. Tried in a private window too and all the suggested Firefox settings, no go.

Also I was able to use primewire.mov to watch videos up until yesterday, but none of them will play for me today. Guess I should try Chrome for them too. I use a private window for those sites.
