Every time I make Firefox full-screen, it immediately crashes and shuts down. I have restarted the computer, uninstalled and reinstalled Firefox, but it still doesn't work.

Every time I open a new site or webpage, the automatic translation window pops up. I don't need translations and I have to choose "don't translate this page" again and again. I've searched everywhere on Firefox and I can't find a way to stop this. It is extremely intrusive and annoying. I don't understand why Firefox should decide for me what I want and what I don't want. Has anybody solved this problem.

After my pc has been on for a while, seemingly random duration, Im not able to open firefox anymore. For example if clicking on a link in discord, or if I close the browser and want to open it again. I've tried refreshing and reinstalling but that didn't help.

Connectivity to www.xfinity.com disappeared...with latest firefox 140.0.4 as near as I can tell. xfinity still works on Google Chrome and Microsoft Edge. Please fix firefox browser so I don't have to go to chrome or edge. thanks!

I received this download from Firefox today, July 22, 2025: xRqj7qhl.html - Size: zero bytes - Kind: HTML text . I've never experienced this before. Is it legitimate? Thanks

When I open Firefox, the master pw window opens with data showing. I can x out of the window & continue. So my data is exposed to anyone who hacks into my desktop PC. WIN 11 64-bit. Please help.

I recently ported from chrome to firefox about 3 days ago and was tryin to access the dropdown menus on this website https://www2.gov.bc.ca/gov/content/governments/government-id/bc-services-card/your-card/get-a-card

I realized it wasn't working so I turned off my adblocker (ublock origin), refreshed the site and still not working.

Also attempted to use troubleshoot mode and still does not work.

Cleared cache + cookies and used troubleshoot mode and nothing working still.

I lastly checked the website was working by opening the same link on chrome after all that and it works perfectly fine over there. Any ideas what could possibly be the issue?? I basically have a fresh install of firefox with no changed settings besides anything that might of been copied over from Chrome when firefox automatically asks you to migrate your stuff over, and used the troubleshoot mode + clearing cookies and cache

Firefox crashed and I cannot recover my tabs from history. I click on restore all tabs and it does nothing. The tabs I was hoping to recover do not even appear in my history either.

I accidentally clicked on a site that was supposed to be a game review site that I found on a Bing search. Now I get pop up ads for fake virus programs whenever I run Firefox.

I ran a scan with Mallware Bytes and Microsoft Defender and both scans came up clean.

I am including a screenshot of the popups.

Any ideas?

Thanks

I have had a google account and a YouTube Channel ([email_1]@gmail.com) for decades. I recently added a new google email ([email_2]@gmail.com) and accustomed my old YouTube channel for [email_1]@gmail.com with the new email, [email_2]@gmail.com. On other browsers when I comment, the old YouTube account with the new email shows up as the commentor. Today, on my new Firefox browser.I discovered that the new email had created another YouTube channel which showed up as my ID for a comment on another YouTube channel. I deleted the new YouTube channel but, when I comment with the brand new Firefox browser, the old YouTube channel I deleted shows up. How can I correct that?

I was trying to setup 2FA on my Mozilla account on Firefox pc browser (140 version). The process completes without issues with Aegis authenticator app, I download the backup codes and I even get the email confirming the recovery phone number was added. On the Mozilla accounts page 2FA turns to enabled. (I'm on Windows11 with latest Firefox browser version)

However after a simple refresh, it turns back to disabled. I repeated the process and same thing happens. Same even on Firefox Android. What could be the issue here?

I'm trying to report a rogue version of this add-on, https://addons.mozilla.org/en-US/firefox/feedback/addon/%7B5c474add-03f0-4c67-9479-f32939d7599a%7D/. The actual add-on is fine and works well. Somehow a version, 1.5, got installed and I cannot keep it removed. Whenever I refresh FF, it shows back up. I cannot find any reference to this version on GitHub or on the extensions page. I have uninstalled FF and refreshed it. Nothing works. It keeps coming back. I also looked in the side-install directory, but there were no extensions there. If I remove the extension under the Add-ons Manager, it removes it and I can install it and it installs the correct version and it works until FF restarts and then the 1.5 version shows back up.

Hello, FF support forum,

I think I have seen a Container retain my login to a site when I open it again after closing it. Is there a way to configure Containers so that they are mini versions of the dump-cookies-temp-data when I close Firefox entirely? I would so love that functionality.

Regards, G.W.

There is one particular website that I use quite frequently. Lately I haven't been able to log onto it without encountering a page verifying I am a human, and I can't proceed (the page just loops). This has happened on other browsers too, though I fixed the problem there by disabling my adblocker. But that doesn't help here on Firefox. Any suggestions?

Hi. I used to be able to just grab and image on a webpage and drag it to my desktop. Now I have to go through the whole rigmaroll of right click and save. Anyone know how I can go back to the faster way please?

Thanks.
