Apparently Firefox did an update (version 136.0.4) in the background while I was using Firefox on March 27. At some point I wanted to save a page to my bookmarks and realized all my bookmarks were missing. I had just used bookmarks earlier, so it had to have been an update. This happened to me before back in January 2025. I was without my bookmarks for several weeks when all of a sudden they showed up again.

I cannot use the instructions to go back to a previous profile, as the two options showing do not have my bookmarks, bookmark toolbar or customized Firefox homepage. I also cannot import my saved bookmarks to get them back. I get an error message when I attempt to do that option.

This is very frustrating, as I use my bookmarks, toolbar and customized homepage EVERY day. I have all my important links saved to bookmarks. Firefox developers need to find out why an update removes bookmarks, as this seems to be an ongoing issue with me. I've used Firefox for over 17+ years and never had bookmarks removed after an update before, so something in an update is causing this issue.

I have no idea at this point IF everything will return to normal in a few weeks like it did back in January. So right now I am without all my bookmarks. Please get this ongoing issue resolved, it's a royal pain. I need those bookmarks to maintain my daily routine for accessing financials, medical websites, etc.

Thanks for any help you can give me at this point. This is the second time it has happened.

Hi, my session with a lot of open tabs has been lost due to a crash. In the profile folder, the recovery and previous files in the sessionstore-backups have been deleted. I tried to recover them using shadow explorer, but these files are corrupted, so I've had no success reading them. Is there a way to fix the corrupted files? Alternatively, because I've had sync enabled for open tabs, is there a log for past open tab synchronizations? If this was stored on the cloud, it may be possible to retrieve that table and restore the list of open tabs that way?

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.

Installed 134.0.2. Bookmarks disappeared. Went to restore backups, receive message "unable to process the backup file". All of my bookmark backup files receive this message when I try to restore.

I don't know whether this happened after an update - there was one a few days ago, but I only realised this morning, after switching on the computer, that all my bookmarks are missing. The toolbar is there, empty, only reading "For quick access, place your bookmarks here on the bookmarks toolbar"... I wish! I tried to restore the bookmarks - but it seems there is no backup to restore at all. Then I tried to check my profiles, but there is only the one currently in use. Then I tried to move a tab to the bookmarks toolbar - and nothing happened. Then I began to panic: toolbar apart, we're speaking about years of bookmarks, most of them related to my research for my books... All the advice in the support seems to point towards profiles and backups, but, as I said, it's clearly not my case... Please, please, please: help!

Is it possible to restore firefox to a previous version to recover all my data? After update, all my firefox pages, tabs, bookmarks and history have vanished. Please help me recover or restore. Thank you!

Hi, I recently purchased a new laptop and want to bring over the bookmarks I had from my old laptop. I had copied what I thought was the profile from the old one and copied it into the new laptop - but I'm not sure of the next steps :(.

When my Firefox crashed today, I chose to restore it rather than troubleshoot. When it was done, my bookmarks icon had disappeared. Yet when I go to the individual websites, I can see that each one is still bookmarked. How can I restore the icon that used to be in the toolbar at top? Thank you for any help you can give. I have been using Firefox for many years now and this is the first time I encountered this problem.

Hello! Recently I experienced some massive issues with my pc and it needed service, it was uncovered that my drives crashed and the data is gone, they tried to restore it but its all corrupted therefore I cant get my bookmarks back in file form.

My account was synched so all my bookmarks surely are in cloud, today I got the pc back from repair, but my account only syncs bookmarks from the spare pc I used during the repair time and those bookmarks are outdated by two years, the pc which went under repair does pop up in the logged in devices list, so all the bookmarks that were there gotta be stored in the cloud, can you help me recover them?

Best regards Sarah

Hi,

I’m writing you as a very annoyed, frustrated and seriously pissed off user.

I’m a senior lecturer at De Montfort University, Leicester, and have been using Mozilla since 2020/21 on my university account, since I don’t want Google Chrome and Microsoft Edge is user-unfriendly shit. Now, my Mozilla account was registered via DMU (technically set up by the university’s ITMS) to run as my default browser, which opened automatically logged-in and ready to go each time I started the computer. This is how it has worked for the last four years and through many, many updates… until yesterday.

Since the last update on Monday, May 19th, all my access records, settings and bookmarks have been completely wiped off. In fact, it appears that my university-registered account has been wiped in its entirety. Strangely, Mozilla Firefox is still my default browser but only opens with a standard default window. More importantly, I was no longer able to log into my account, as if my account no longer exists… which also means that all my bookmarks and links to important websites within DMU and externally have all disappeared. It will take me at least 1 week (if I focus on nothing else) to find and restore them.

So, how was such a car crash of an update actually possible? Please note that ITMS at DMU is placing the blame and responsibility of this fuckup squarely on you. Furthermore, why was this update actually necessary? Mozilla Firefox was until yesterday a far superior browser in terms of user-friendliness and style compared to Google Chrome, Microsoft Edge or Apple Safari. Now it’s little more than a cheap, equally flawed Microsoft Edge copycat both in style and user-unfriendliness!

But even worse, I now find out that Mozilla like all those "revolutionary, democratizing" tech companies cannot even be bothered to be accessible for contact when in need for support. Anyway, I would like to know how your update could wipe out my account and all the bookmarks just like that, as if they never existed in the first place. And how do I get my my original settings back?

Very disappointing.

Regards,

Markus
