Firefox Support Forum

My computer was compromised And as a result I had to repair and re install my Microsoft operating system windows 10 pro. That procedure wiped out my Firefox browser and now I have no record. Is there a backup that the browser keeps on a cloud.

I went to a local website and ended up getting virus warnings, see photo. I doubt if it's real but I don't know how to get rid of the messages, or scan for the virus? I scanned with the Windows virus protection and the computer came back clean. I can and have turned the computer off and back on, no help.

Thanks

I saw this same issue posted on here, but I press the shift key while using the Firefox browser and what appears to be a developer menu pops up at the bottom of the page, the crappy thing is this is occuring on my laptop so my keyboard is part of the computer lol

When PC is activated Firefox will open and then close and reopen. When opening another app and starting to work in it, out of the blue, the app will quit and Firefox will open automatically. Not at all times but very aggravating when it does happen. More often than not.

Please help!! I use windows 8.1. After using the recovery function to a previous backup Firefox icon looked like a blank page and when I tried to open I got an error message stating that I was attempting to use an older version of Firefox which could have a problem or a virus. There were two choices, one was to exit and the other was to create new profile. Clicking on the exit did not resolve anything so I clicked on create new profile. That resulted in a new install of Firefox. I now have lost all my saved bookmarks!! How can I get them back into the new install of Firefox? Thanks. .

I set up Firefox on a new laptop yesterday and it came up with all the bookmarks etc I had previously. I was prompted to set a profile so I set default user. Now I have lost everything I had. How do I get it all back. Do I delete Firefox and start over? Richard Culver [removed email from public]

I've recently been opening Firefox to find that my tabs are missing - MIA. I haven't had any problem until recently. I am running the following version of Firefox: Firefox 108.0 (20221208122842) Details Installed on: December 13, 2022 at 2:47:02 PM Status: The Update was successfully installed

Unfortunately, when I did a search in help for tabs - the suggestions were above my pay grade. I tried some of the suggestions, but they didn't seem simple enough for me. (I'm 71 but somewhat computer literate having taught software). Hopefully, someone can help with this. My email is: [email removed from public forum]

Thank you for your assistance, Jane McIntosh

Windows 10 pc can not start,I have gone through automatic repair and diagnostics steps,but am now on advamced options and think I need to Reset it.This will lose Firefox.When I install it again will I be able to sign into my Firefox account to retrieve bookmarks and passwords?I am very nervous about this,don't even know how to install Firefox,as someone gave me the computer and it was already in there. I am a tech dinosaur!Thank you in advance for any help.Lesley

When I close tabs, and the computer stops working and I check the Task manager it turns out that firefox still runs 20-30tabs in the background when most of then have been closed and have just 4 running!!!

This occupies 100% of disk and CPU, and thw laptop stops functioning and freezes!!!!!!

And this happens all the time! How do we make firefox actualy close the tabs properly?? Without having to dig through task managerto close them again one by one?
