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"

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."

Default homepage is yahoo. Since the update to version 149, if I do a search from yahoo, the new tab that opens with the search result is blank most of the time. I have to click reload for the search results to show up.

Is anybody else having that problem? Seems to be yahoo search specific but not 100% sure.

Hello I got a pop up or it was new tab informing about new firefox functions. It was about profile creation and management. Now i have two profiles and cant switch back to my old one. I cant seem to be able to delete new profile to return to my old one.

Okay. So I downloaded Firefox on my chromebook from flathub, but it keeps crashing. I open a new tab: it crashes. I close a tab: it crashes. I don't open or close anything: it crashes. I don't touch anything: it crashes.

I've says that either my theme or one of my add-ons is causing the crashes but I removed my theme and it still crashes and I can't remove any add-on because it crashes if I try to open a new tab.

Now, did/does anyone else have this problem or am I just stupid and missing a very obvious thing.

Hallo, zum wiederholten Male hat sich meine Firefox Startseite verändert und meine angelegten Tabs in der Linken Spalte sind verschwunden. Ich habe die Tabs sorgfältig angelegt und wenn Sie mir diese Einstellungen nicht wieder anlegen können, dass wechsle ich meinen Browser, weil das sehr nervig ist und unangenehm! Freundliche Grüsse, Wilfried Schlachter

There is a document produced by Mozilla Support entitled Install Firefox on Linux. There are tow commands explicitly for Trixie. They both start with cat <<eof. the first one didn't work and was obviously incorrect. after much digging i found that wrapping piece eof like this 'eof' works. did not figure out, someone else did. hope mozilla support will update file. < p></eof.>

I was browsing for vacant jobs in LinkedIn and ended up on this page: https://www.linkedin.com/jobs/view/4400116024/?trackingId=&refId=&midToken=AQHkKqfITpiwdw&midSig=2f8JsuceFtMYc1&trk=eml-email_jobs_application_rejected_01-similar_jobs-0-similar_job&trkEmail=eml-email_jobs_application_rejected_01-similar_jobs-0-similar_job-null-g3nlj~mo2hn6z8~of-null-null&eid=g3nlj-mo2hn6z8-of&otpToken=MTAwMjFlZTQxNjJhYzljM2JlMmYwMmVkNDAxYWU3YjA4NmNiZDQ0MzlkYWQ4NTZjNzljMTAxNjg0ZjU4NWZmM2YzZGZiN2JjNTVjNWZjZTc3YjhmZDg3ZWQ5YTExZWUyMDg1N2Q1YzI4OGNjNDU0MjU3YTEsMSwx But pressing the Apply button, did not take me to the application page, but instead a page that was saying: "Be careful. Something doesn’t look right. Firefox spotted a potentially serious security issue with jobs.tuvsud.com. Someone pretending to be the site could try to steal things like credit card info, passwords, or emails." And there was no option to ignore this and just go to the site??? I needed to open MS Edge instead, to be able to apply for the job???

bold text whenever I go to a password needed site (account), firefox says passwords blocked and asks for a touch ID or a Firefox (?) password WHICH I DON'T HAVE. Can i change my Firefox password? If so, how??
