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.

I get scam messages that say "Trojan virus detected!" on Mozilla Firefox which I cannot delete. I have run antivirus scans which show there is no virus or malware. I have shut down the desk top. How can I go to reinstall Mozilla Firefox default settings or do you have another solution?

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"

When I try to sign in from Firefox I get the message "Unexpected error". I can sign into my account online but only using Google to sign in. If I try to sign in to Mozilla directly, I get the same message.

Hi there,

I woke up this morning and opened firefox. Normally it opens the days previous tabs and this morning it didn't. When I tried 'restore recent tabs' it didn't do it. When I went into history and found the previous day's back up and tried to restore it also failed. Can you help?

Best wishes, Inez

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

I assume Mozilla developers are working on this?

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."
