Firefox Community Forum

A few days ago (today is November 9th 2025), my PC restarted itself while idling and when I got back, all my bookmarks in Firefox were just gone. The bookmarks toolbar, which I use constantly, was also gone. Furthermore, I can't even create new bookmarks. And I mean of ANY sort. Doesn't matter if click the little bookmark star when I'm on the page I want to save, or if I manually try to type it in by right-clicking the toolbar and choosing "Add bookmark..." None of it works!

I tried going to "Manage Bookmarks -> Import and Backup -> Restore" where I see 12 restore points. I've tried them all, but I get the same message every time: "Unable to process the backup file"

I've searched the Mozilla support articles and have only found one other entry from a person who seems to have had the same problem, here: https://support.mozilla.org/gl/questions/1504803

This person managed to solve it themselves by using the "Refresh Firefox" option, so I tried that, but it didn't work. The only thing I got out of it was losing all my extensions. I had been warned about that beforehand, so while it's a little more than just annoying that I've lost my Avast! Password Manager, which had a LOT of passwords I can't remember, not backing that up manually before running the refresh was entirely a brain fart on my own part.

Just to be sure, I've checked my Windows Update history to see if the culprit could be Windows rather than Firefox, but the last one was the 25H2 update that ran on October 17th. If that had been to blame, the problem would have manifested itself much earlier, so I'm fairly certain that has nothing to do with it.

So, two problems to solve here:

1. 1 - How do I fix this bookmark problem?
2. 2 - Is it perhaps possible to restore my Avast! Password Manager?

I would be VERY grateful if someone could help me with this! Like the person in the linked post, collecting these bookmarks has taken me over a decade and they've been used so frequently that - at least for some of them - I don't even remember the URL's of the sites anymore, because I literally haven't typed them in manually for years.

I really do like the new vertical tabs and I have them set to be just icons until you hover the mouse over them and then they fly out and I can read the names of the tabs. My problem is that when I switch a tab or do anything that makes the tabs expand to see their full names if I take the cursor off they fly back in but if I put the cursor on any area of how far the tabs came out to in the next few seconds they come out again even though I haven't put my cursor over the tab icon. This is really annoying for forums and really for general browsing as if I switch to a tab and want to interact with anything where the tabs came out to I have to wait like 5-10 seconds before I can click anything on that part of the page or else the tabs come flying out again. Is there any way to make it so the second my cursor isn't over the tab fly out that they will go back to the compact mode and won't come back out unless I hover over the tab icon again to alleviate this problem? I find I will often switch to a tab and then move my cursor off to the page and the names collapse so there are only icons left but I try to interact with something on the left side of the page and the tabs fly out way before my cursor goes near the tab icon and I have to take my cursor to the right then try going back to interact with that element and most of the time I have to go back and forth a few times before the tabs stop flying out so I can interact with that portion of the left side of the web page. I really like the vertical tabs but I want to be able to edit the time it takes for them to not fly back out if your cursor goes to where they had flown out to immediately, so zero seconds, instead of the 3-10 seconds or whatever it is set at by default.

Thanks!

hi i was wondering if there is a way to remove this shadow cuz i have the adaptive tab bar extension and i think it will look way more better without this shadow enabled

This video file cannot be played.(Error Code: 102630)

I’m getting this error for some reason, and I can’t figure it out. I’ve tried downloading various support files for different codecs, yet I still can’t play videos on websites or live videos like YouTube livestreams.

I’ve tried reinstalling the browser, VLC, and updating the media drivers, but it still doesn’t help. The same videos run fine in other browsers like Edge, but for some reason, they won’t play in Firefox.

For the third month in a row every, EVERY!!!, password I have saved to my Firefox browser have disappeared. Poof, GONE! For as long as I've used Firefox, 10-15 years, it had never happened before September of 25 Some of these password, prior to September, I'd had for years. Yes, I know I should change them over time, but I haven't. How do i recover them? I'm really Pi---d off. Help!

26200.6899 - Windows 11 pro OS version 144.0.2 (64-bit) - Firefox version

After a few minutes of usage, firefox keeps freezing and crashing. Very frustrating. Seems to have started happening after recent OS upgrade.

Hello

when i scroll to fast, it does this. That would be a minor issue, however, it shifts where the cursor is active, which is mildly annoying. Also, I am using some kind of theme, i believe its Aurora from Firefox.

Thank you for fixing the issue.

Best Regards

I'm sure someone will have answered this somewhere but is there a way to backup and restore the native Mozilla Tab Groups. I've seen plenty of people recommend other Group Tab extensions but I like the inbuilt one combined with Containers.

I've read that you can backup the whole Mozilla profile folder and this should work but I've tried that and failed, I used a few extensions to backup sessions and that also failed.

Any help would be appreciated.

A few days ago I started getting the below message when logging into my AMEX account. Any ideas how this can be fixed?

Internal Server Error - Read The server encountered an internal error or misconfiguration and was unable to complete your request.

Reference #3.66c83017.1762797797.7b5513f5

The "X" to close a website banner message is covered up by the vertical navigation bar on the right side of the screen in both minimum and maximum display modes. So the message banner cannot be closed.

I use the same laptop at two locations. I have different printers at each (both HP, one a laser the other an inkjet).

Most of my time is at location 1. Typically I can print without a problem. Recently in Firefox ONLY I have been unable to print at location 2.

Scenario:

1. I print to the laser printer at location 1. No problem.
2. I go to location 2 and choose to print - the print dialog appears with a "spinner" and it does not go away.

I have to cancel using Esc. I am unable to print at all from Firefox. Typically if I close Firefox after that, it looks closes but is still shown as running in Task Manager.

Other programs such as Word and other browsers bring up a dialog box showing that "the printer cannot be contacted" and allows cancellation. At this point I can choose the local inkjet printer and all is well.

HELP!!!!
