Help, My computer performed an automatic update, rebooting itself and all the history on Firefox has been lost all my open tabs have disappear. I followed other instructions to open the Profile Folder, but the only 2 files there are the ones created after the reboot. There are no previous files. Thanks, Juan

From one day to the next I have the problem that I can no longer log in to the Google site. When I press the "log in" button, the page loads for half a second and nothing happens (screenshot 1). When I then want to access YouTube, the following page appears (screenshot 2). Everything works with other browsers. When I press "Gmail" on the Google homepage, I'm suddenly logged in and in my inbox. But I can't go to YouTube from there either, and I get back to the "screenshot 2" screen. I then have to log out of my account in gmail and log in again to access YouTube. If I then close Firefox, everything starts again from the beginning.

Good day, everyone,

I've been using Firefox for several months since switching over when the migration to Manifest V3 in Chrome gained momentum. Initially, Firefox worked flawlessly, but over the past couple of months I've encountered a recurring issue where downloads often fail -- sometimes right at the start and other times midway through -- especially with larger files.

I've encountered this issue across multiple machines, and changing the destination drive where the files are saved hasn't made any difference. Interestingly, the same files download without any issues in Chrome, so I've ended up relying on Chrome exclusively for downloads.

Has anyone else experienced this issue?

Thanks in advance!

My GPU is the integrated GPU on the Intel U7-155H CPU. When some AVC videos are played, the browser reacts extremely slow and the video image is glitched and at a really low rate of frame, and the video decoding engine seemed to be 100% occupied as shown in the task manager (normal video playback never occupied so much of it). Seems like AV1 encoded video never triggered the problem. The problem doesn't always happen, but at a rather high frequency. This never happened before I updated the Intel graphics driver from 32.0.101.5972 to 32.0.101.6129. The problem seemed not to happen on other browsers such as Microsoft Edge.

Hello, I'm currently using a Macbook Air, Early 2014, that still works perfectly fine for my needs. But it runs with OS X 10.9.5 and Firefox 78.15.0esr, that unfortunately can no longer be updated. That wouldn't be a problem to me since I do a very limited use of the computer, but now I'm getting the message "Your Firefox may start to have problems on January 14, 2025 since updates are not available for this OS". What should I do if I still want to use this device with Firefox to browse the internet? If it is impossible to keep using Firefox, any suggestions for an alternative browser that may still work? Safari is no longer an option. Thanks a lot for any and all replies

As title, MS defender keeps detecting trojans everytime firefox is launched and while I'm pretty sure it's probably just a false positive its just getting rather frustrating and now more so, worrying that it's constantly happening.
