Firefox has been my browser of choice for well over 20 years. I have a game I play every day (from FaceBook) just this week when I try to go to it on my laptop - it says your browser does not support WebGL. it has always opened using Firefox - this is a new error message. and the computer is only 5 months old and has Windows 11 on it. I do not want to switch to Google or Edge.

Like I said - opening the app worked every day up until about a week ago. What gives?

My Macbook wasn't responding, so I restarted it and force quit all applications. When I opened Firefox again, none of my bookmarks showed on my bookmarks bar. The bar itself is not hidden. I checked to make sure I have the same profile I always use open and I do. I also tried to go into Bookmarks, Manage Bookmarks, Import, but nothing is available to import.

Why is there not an option to say "no" to Firefox automatically loading when you restart your computer? There is only "yes" or "not now". I am not interested to my internet browser loading and opening once I have restarted my computer. I use my computer for much more than browsing on the internet. I am tired of always having to click the "not now" option to only have it show up the next day or two days later, where I then have to click, yet again, the "not now" option. I even went into Firefox settings and have not found an option to "op out" of this particular feature. Can you please add a "no" option to automatically opening upon restart.

Firefox OFTEN starts with a screen which reads, Sorry we are unable to restore previous sessions. OF COURSE it cannot restore previous sessions. I leave the box unchecked next to, "Open previous windows and tabs. I check the setting, delete all data on closing. I take great pains to delete data including cookies, website settings, etc, on closing, EVERY session. I NEVER want previous tabs, windows or sessions restored. HOW do I program FF to REMEMBER the setting, box unchecked next to "Open previous windows and tabs"

Request to enable X25519MLKEM768 on detectportal.firefox.com for improved privacy

Dear Mozilla Team,

I kindly ask you to add support for the X25519MLKEM768 hybrid post-quantum key exchange to the domain detectportal.firefox.com (the URL used by Firefox connection testing). This small change would significantly strengthen privacy protection for millions of users who rely on Firefox's connection test URL. As you know, this mechanism has already been successfully implemented on almost all of your other domains. Extending the same protection to detectportal.firefox.com would ensure consistency and close the remaining gap. Thank you very much for your ongoing work on privacy and post-quantum cryptography. I would greatly appreciate your attention to this request. Best regards, Anonymous

Quote from the article

"Its capabilities are a step change from the previous best models. Given the challenge of attacking the Firefox web browser’s JavaScript engine, Anthropic’s previous most powerful model Opus 4.6 succeeded just twice, compared to 181 times for Mythos. Most worryingly, the team found that engineers with no security background could use it to develop successful attacks overnight."
