Firefuxxed was refusing to open new tabs so I shut it down and restarted it (always fixes it) and all my pinned and open tabs were gone with no way to recover them, it took me half an hour to manually restore the pinned ones one by one but not all of them as I cannot remember all of them let alone all the open tabs I had (hours of research gone down the toilet).

There should be a way to backup and restore pinned and open tabs so this doesn't happen, the history option does nothing.

OS: Linux Mint 22 fresh install from a week ago Previous version of Firefuxxed updated after this shamossel.

In my Win 10 PC, Firefox has been set to update automatically as it is recommended.

136.0.2 (64-bit) is the most recent one that updated automatically.

Now all my extensions have been wiped out, my workspace changed.

That is such a breach of integrity, and a lack of respect for the user, and his carefully set up work environment, when an Auto-Update just molests my work environment. And then I have to take out hours from my busy routines, to devote to restoring everything to how it was.

There is no rollback feature for Updates, esp when Updates do the havoc they do.

There is no proper Session Management, and a standard protocol for saving, aggregating sessions across different installs, rollbacks, etc, and having the most updated, and complete one, where the onus is on the user not losing data.

Now I have to go hunt around for the past profiles, and name the present one as old, and hope that Firefox functions with integrity, and completeness to restore my whole work environment from the last profile. I'll of course be losing whatever work I happened to do in the new profile now. One never knows how complete these profiles are to reconstruct things exactly the way they were.

Strange. I always believe that stability, and integrity, and a dedication towards that on behalf of the user would be the primary goal. Now it's all about chasing something else, some bells and whistles, and faster performances, and throwing stability, and data integrity under the bus.

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.

Just updated to FF 141.0.3. The browser had advised me to restart to finish the update. So I did. But in doing so, not all my tabs were recovered.

Most were, but like 3 were not.

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 :(.

EVERY TIME I CLOSE FF WHEN I REPOPEN IT, I END UP BACK AS IF I JUST INSTALLED IT. ALL MY BOOKMARKS ARE GONE, ALL MY EXTENSIONS ARE GONE, LIKE I JUST INSTALLED IT.

I'VE TRIED UNINSTALLING AND REINSTALLING AND IT STILL DOES IT.

Hi

I've just booted my machine and opened Firefox, only to be presented with a completely fresh install.

All my settings, bookmarks and history gone. It was fine yesterday when I closed it and powered down.

I'm running Kubuntu, I've checked the .mozilla folder and nothing...it's like my profile has just been overwritten.

Not happy at all, I'm starting to dislike Firefox.

Can anyone offer any help or advice please?

Thanks in advance.

Hello

So a funny story happened today, I used CC cleaner to help clean my PC now I have it set up so it does not touch Mozilla in anyway yet after an update those settings got wiped and when I used the program it wiped out everything I had in Mozilla, history, saved passwords, tabs, EVERYTHING.

The last time I made a backup to my bookmarks was 6 months ago, a lot has changed since then, I tried to use the restore function however those also got wiped out, so I decided to use the old bookmarks, yet it doesn't work, for some reason it tells me that it doesn't have any bookmark data in the file yet Chrome can read and import the bookmarks from the file, if I try importing stuff from Chrome it also comes up empty, as an experiment I made a new export from Mozilla and tried to import it and got the same error. I still have 2 bookmarks and those can't be deleted no matter what I do, I kept trying to delete them however they are stuck there no matter what I try. This laptop is a new one I got on the cheap after my laptop had a problem with it's hard drive, I made the backup right before the switch.

Does anyone have any ideas about what exactly happened and keeps happening?

I was asked to create a new profile in order to keep using Firefox, despite never having an account. After I clicked okay, it opened the new version of Firefox, but without all the passwords, bookmarks and history of the past few years. This is really inconvenient. I have since then made an account, but the fact that I can't find any of this data anywhere has me worried that every time I update Firefox it will wipe my account.

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

I have just restarted my computer following installation of updated software. I find that Firefox has lost all my bookmarks. Are they stored somewhere, and if so how can I recover them?

Out of a sudden all of my bookmarks were lost. I tried importing bookmarks i had previously saved in an HTML. Did NOT work. I tried "revert to older date bookmarks." Did NOT work. I tried "import from another browser."Did NOT work. Funny thing is that with the same HTML file i extracted from mozilla when i made a copy a couple of weeks before, i was able to upload all bookmarks to Opera but not to Mozilla!!!! The image below for the non Greeks reads "Failure to process copy document".

I keep a lot of tabs open (~60) in any particular session - I find it's faster in this way to get back to a site.

About every six months or so, I lose *all* these tabs because of Firefox's inadequate session backup system. It only saves two or three total backups, some of which are completely out of date. But the worst scenario is when (1) some site pops up a new window; (2) I mistakenly close my main window before the new window; (3) I open this new saved window once or twice by accident, causing my 60-tab session backup to be overwritten.

Using a third-party session manager (I have tried all the well-known ones) can mitigate this problem, but doesn't really solve it because the re-opened sessions aren't quite in the same format as Firefox sessions and so lose information. In particular, I often lose each tab's icon as well as metadata for Tree Style Tab.

Could Mozilla please consider a more robust session backup system for Firefox? All it would take (I think) is to allow the user to choose the total number of backup sessions and the frequency at which a new session is added. Thank you!

After Firefox requested to be updated, I lost all of my bookmarks. I tried to go in and "restore" them but there are no backups to restore from. How do I get my bookmarks back?

I don't know what you're doing but EVERYTIME I do an update lately, something goes wrong. Today after update, my STGs are affected and ALL ARE GONE. I do NOT believe this is their fault. And you put this dang auto Startpage when launching window, I did NOT ask for that. I am so pissed, how do I get them all back? I had things I was working on that were very important. What else did you add to FF that I don't know about? I don't want your updates anymore. You screwed me big time. And I don't want the extensions YOU think I should have: Google, eBay, Bing, etc. wasting my space. I'm not the only one either, seen lots of complaints.

HOW DO I GET THOSE TABS BACK??????

Since updating Firefox on June 30, 2025 on my Dell desktop computer that runs Windows 10, most of my bookmarks are no longer visible. Only four of my bookmark folders are visible and most of their contents have disappeared.

However, 1) my uncategorized bookmarks - those in "other bookmarks" are still visible, and 2) If I go to "Manage bookmarks" and do a search, I can find all of my bookmarks including those that are no longer visible.

In addition, I can no longer add or delete bookmarks. It looks like I can do add a bookmark and it will let me go through the steps of adding a book mark - it even says I can put it in all my old folders that are otherwise no longer visible. But one I complete the process the bookmark does not show up.

I have read multiple Firefox Help articles about disappearing bookmarks and have taken all the steps suggested including: - Attempted to restore backups of bookmarks - didn't work. It shows me the multiple old backups but when I try to restore one I get the message "Unable to process the backup file". I have tried it with at least four of the old backup files - all without success. - cleared cache - did troubleshooting mode - refreshed Firefox - uninstalled and reinstalled Firefox - looked to see if I had a different profile other than my default profile that I could switch to. I do not see another profile.

Nothing has helped. Any suggestions would be greatly appreciated.

Thanks
