Firefox has been running incredibly slow. I currently only have this window open, but if I open my task manger it shows 10 Firefox windows running. If I right click and end task, it will end the task, but shortly there after a new one will pop up. 1 of the is running in efficiency mode. I assume this is what is slowing down performance, but I do not know how to fix.

I've been trying to set up 2fA on my firefox account, the whole process seems to work, I downloaded the backup codes and entered one to confirm and then got confirmation that 2FA was enabled (see screenshot). However, after reloading the page 2fA is shown as being disabled and indeed if I try to log out then in again I'm not asked for a code. I've tried this a couple of times now and it does the same every time. The auth app I'm using is Aegis.

Does anyone knows why this is happening ? Thanks.

[Edit: I just saw that after each time I tried to set it up, in "recent account activity" I add an error saying "Two-step authentication failed" which doesn't really makes sense...]

W 11 May, 2025 update really made my computer unable to go online in any way and I had to restore. But FFox updates to have made it impossible to communicate. My phone has trouble s too. So, how do we make stick telephone permissions for, say: G Voice page https://voice.google.com/u/0/calls now? Thank you

Seems I've noticed an issue with playing of YouTube videos the last few days. It seems that either the video(s) is slower to load and/or is slower to play. While it's not terribly slower in human time it's slower than normal in computer time. I'm not having this problem in Chrome. Cookies and cache are cleaned multiple times a day. So, I'm a little stumped as to why I'm having this issue. Any comments would be appreciated. Thanks

when attempting to move Firefox bookmarks to my new computer, I click import data within the Firefox page. The computer asks me to select the file. I have no idea where the bookmarks reside and cannot find a file. What is the procedure to get this done?

When trying to do a search for a video in YouTube Studio, the search seems to freeze. Doing a similar search in Microsoft Edge works OK. This problem started happening several months ago. I've tried clearing the cache for YouTube pages.

Firefox (current version:137.0.2 64-bit) does not allow drag from outlook on the web and drop on windows 11 file explorer. It shows a forbidden sign when i am dropping on file explorer.

How this problem can be solved?

I am receiving pop-ups from what appears to be Mozilla Firefox saying: System is infected! Viruses detected, Turn on protection and delete viruses. The virus identified is ZEUS.2020 Trojan. Click here to scan and clean via: d3av3500fes73a78mk0.mosgdefender.com This link doesn't work. So, how can I get this issue resolved? Any help would be appreciated. These pop up happen frequently one after the other. I appreciate any help solving this issue. Thank you, Tricia Hawkins

in FF 137.02 Win11Pro there is no reopen previous session option in the history menu, even though in settings, history, "firefox will" is set to remember history. We tried reinstalling FF. No luck.

Is there a way to reopen the previous session?

Has that feature been deleted?

WHEN I SIGN INTO MY OUTLOOK ACCOUNT, FIREFOX IS BLOCKING MY CONNECTION. IT WILL NOT CONNECT TO SECURESERVER.NET. I CANNOT ACCESS MY E-MAILS IN FIREFOX CURRENTLY. PLEASE HELP! ALL THE TECH PEOPLE SAID IT IS THE BROWSER????

I AM HAVING THE PROBLEM ON THE OTHER COMPUTER. I THINK THIS PC IS O.K.

More frequently than I care to admit, I seem to close FF instances which I don't want to close (such as my connection to Whatsapp). I then miss important replies or questions. Of course I can reach out to 'History' and try to find the closed Tab or Window... But that takes time.

I'd suggest adding/removing a 'protection' flag to a tab (eg. on right-clicking), so that, on trying to close the tab, or close the window containing the tab, I get a warning...
