Recently, Firefox updated and ask me to setup a profile, which I have not yet done since importing my data from google chrome in 2025. After skipping the setup, Firefox then deleted all my data and it has since been irecoverable. I have already checked the box last update that specifically said to not ask me again for setting up my profile. After the recent update, the question popped up again and now I cannot recover my original profile, all my browsing history, all my browser-saved data, and all my cookies and logins

I can't find a place to manage my payment methods. The only place I found that was when I check out and fill in my information in a store website.

The browser suggests my card and under that it says "Manage payment methods".

When I click that it opens "about:preferences#privacy-form-autofill" and then quickly becomes "about:preferences#privacy".

Please help thanks

I live in Northern Ireland which is part of the United Kingdom. The full name of the UK is as follows "The United Kingdom of Great Britain and Northern Ireland". When I select my country as UK, Firefox changes it to GB. Northern Irland is not in GB. Great Britain consists of England, Scotland and Wales.

Windows 11 23H2 - Firefox 131.0.3

I use firefox on laptop with a usb keyboard, On the laptop CTRL+Shift+P using Left CTRL+Shift+P and Right CTRL+Shift+P works as intended and opens a private window.

However on the usb keyboard using the Left CTRL+Shift+P doesn't work to open a private window while the Right CTRL+Shift+P works normally.

After a bit of trial and error i worked out the issue with the usb keyboard is the left CTRL key. It works for other shortcuts such as CTRL P but just not for the new private window command.

I tried loading firefox in troubleshoot mode to see if this was an addon issue, still no good. Tried 2 different keyboards from the one i use daily just to see what would happen and still the same issue.

Any suggestions? im at a loss.

I keep getting pop-ups in the right lower corner from "mozilla firefox" (not sure if they are legit). They will say: "zeus.2020 trojan detected" or "virus detected" or "system is infected", etc. All have "Mozilla Firefox" in the upper left of the pop-up, and "via rgfirewall.xyz" at the bottom. Is this truly legit, or is it just a nuisance? I've just been closing them with the x or dismiss buttons.

I read online that Firefox is planning on implementing AI features. Given the track record of AI in other browsers leaking private information, bogging down connectivity, and generally being a nuisance towards users, I was wondering if there will be opt out features in future updates? Or know of forum threads that will update with tutorials on how to turn off AI features?

If not, does anyone on this forum have recommendations for no-ai browsers?

I've seen cites that prove that Mozilla's latest policy updates (thanks for no notice) are now positioning Firefox to sell our data for both ad targeting and AI training purposes. I oppose both, and have no use for Firefox if it joins those already disrespecting and monetizing user privacy in those regards. How do I a) ensure I'm getting the plain language notices of further policy updates, and b) register my dismay with Firefox for this betrayal? While you're coming up with an answer, I'll be discontinuing my monthly support for the Mozilla Foundation. I have HAD IT with the greed people ruining everything.
