Before reinstalling Windows, I made a backup, but since I didn't update the system until a day later due to work, I forgot the backup password. I've tried every password I could think of, and I don't know what to do now.

My bookmarks have stopped working. When I went to Edit Bookmark I found they are all empty. I can create a new bookmark as usual, but I have over 300 bookmarks that no long function that are very important to my work. Is there any way I can possibly restore them, as my work depends on them?

Firefox prompted me to update, I hit download, my entire PC froze, I restarted the computer, when I opened firefox again and hit "restore session" it restored a session that I had opened months ago. When I checked my history, everything after that older session had been deleted. All of my history from the past few months has been deleted. I tried a few different solutions from trying to research the problem, nothing so far has worked. The only thing I have found is a session restore error saying "could not decompress file", but I could not find the file it was attempting to decompress. This is the error message I found.

Any help is greatly appreciated. I'm one of those people that tends to have way too many tabs open at once due to poor memory, and losing months of tabs and progress is a huge setback. I'm very desperate to get the history and tabs back.

All my bookmarks disappeared and the bookmark button does not work. I have refreshed Firefox - no change. I have uninstalled and reinstalled Firefox but still no restoration of Bookmark button functionality. OS Win10

An hour ago I had all of my Firefox bookmarks. Ten years of meticulously filed and regularly culled references that I use multiple times daily. I rarely log out of Firefox sync, so that I can keep them up to date.

I now have no bookmarks and no tags.

For some context, two things just happened simultaneously. So, I'm not entirely sure which is the culprit.

1) Firefox just updated and I rebooted my computer.

2) Norton 360 updated sometime in the past two days. I attempted to familiarise myself with the new interface. Foolishly, given the track record of Norton-360-for-breaking-your-games, I ran the disc cleanup, which recommended I remove approximately 400 Mb of data. Norton stated this data was temporary files. If they were indeed my bookmark history, nowhere did Norton indicate they were bookmarks. Also, never have I encountered a disc cleanup that wholesale wipes bookmarks. I do hope Norton is not the culprit and this is just a glitch, because if this were due to Norton having no safety net for deleting an entire library of bookmarks - and they can't help me restore them - then that will be the final nail in the coffin for me doing business with Norton.

The suggestion to go to Import and Backup in Firefox, then click Restore, offers only the option of Choose file... - and then launches nothing.

Currently, I'm seeking any means of restoring my bookmarks. Any help would be appreciated.

I had presumed that I was taking reasonable measures through my Firefox Sync settings to protect my bookmarks and ensure they could be restored in the event of accidents. If these bookmarks are permanently lost, the amount of work I've just lost is quite the blow.

Edit No. 01: After writing this, my Bookmarks Toolbar is also now empty. Perhaps it had wiped earlier, but was merely waiting for a refresh to take effect.

Edit No. 02: Also, it seems I am unable to create any new bookmarks. I shall read the help suggestions relating to that now, to see if it's a relevant issue.

I AM HAVING THE SAME PROBLEM AGAIN, I HATE HAVING EVERY SINGLE ONE OF MY TABS DISAPPEAR WHENEVER IT CLOSES WEIRDLY AND I LITERALLY CANT RECOVER ANYTHING, AND IT GIVES ME SOMETHING NEW, WHAT THE HELL EVEN IS THIS FIRST FILE, I HAVE NEVER GOTTEN THAT JSONLZ4 FILE E V E R!!! AND WHEN I TRIED TO DO THE SAME METHOD OF REPLACING THE FILES WITH ONE OF THE OLD RECOVERY FILES LIKE IN MY OLD QUESTION, IT DOESNT FUCKING WORK, SORRY TO SWEAR BUT ITS UTTERLY RIDICULOUS DUDE!!!

I am incredibly frustrated by the continuing problem of all my Bookmarks disappearing with the usual "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." This issue has been going on since NOVEMBER!!! I usually manage to get my Bookmarks back by closing all txt files that I need to keep open, store them in a new folder on my laptop, and then restart my laptop. This time, it didn't work.

Can anyone steer me to a permanent solution to this problem?

Thanks, in advance, for any help offered.

My wife's Firefox was triggered from an e-mail link and in the process got updated to release 141.0 The result is that the tabs from the previous verion have not loaded. Can I still recover them?

The launch of Firefox Profiles seems to have obliterated everything in my account: bookmarks, history, open tabs, and extensions are all gone completely. I have an option to import files from another browser, but not from my own past firefox. I logged into my Mozilla account, but I didn't have any other devices so I think it was still unable to recover the data? Is there anything I can do about this, or is all of my data truly gone?

My Win10 & Win11 pc's updated to this version and they all have the same problem: The bookmarks have disappeared. Including my pinned bookmarks on FF's opening page.

I also just noticed that there are no "toolbar items".

Hello!

'I have the menu bar enabled-

When I go to "History", the settings

are greyed out.

I want my tabs back!

I restarted Firefox today to find you have removed all my 100+ tabs, which I had arranged in folders, and replaced the vertical settings I had with Tree Style Tabs, which in the past has always run slow. I was greeted with childish graphics inviting me to set up a profile and offering me an introduction to Firefox. I have been using Firefox for years, mostly happily, until you screw up the view I had spent hours setting up. You are turning into a cheap Microsoft but with even less consideration for your users. Will you correct this or do I need to search for a new browser? Francis Shennan, LL.B Writer, journalist and law lecturer.

I deleted a profile not knowing it would delete everything I had. How can I undo it? I didn't want Firefox Profiles, it was forced. I deleted it, and everything just got deleted. Can someone please help revert this? Thanks.

My PC died and I could not boot from bootable flash drive.

I had been backing up the system with Acronis to a WD Passport.

I purchased a new computer, and when I did a restore, upon starting Firefox, I did not have my old bookmarks, which are many.

Aren't they stored in a backup? If so, how do I get them back. I'm sure that some of the bookmarks came over from Netscape Navigator.

Thanks,

Bob

Rebuilt my computer, restored Bookmarks from 'bookmarks-2025-08-30.html' but the original 'Other bookmarks' (just below 'Bookmarks toolbar') is now empty and has been moved to the bottom of all my other bookmarks in a new 'Other Bookmarks' folder. How do I get the contents back in the 'Other bookmarks' (just below 'Bookmarks toolbar'). P.S. I have a backed up 'bookmarks-2025-08-30.json' as well as a ' bookmarks-2025-08-30.html' available, if that would help. Regards and Best, NP_145
