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 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??????

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 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?

I've tuned in to Firefox this morning to find that I'm kind of shut out, no access to my usual apps, and required to enact some difficult backing up etc. When I explore, it seems to relate to Windows 10 losing its backup from Microsoft. But I'm running Windows 11, not 10. What's going on? Is this legitimate? If so, why is it complicated and why wasn't it forewarned (by Firefox)?

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.

Firefox updated. I know no longer have access to my bookmarks, saved links, and passwords. How do I revert back to previous version of Firefox? How do I retrieve access to my passwords, bookmarks, and saved links/pages? I will need easy step by step instructions.

Any assistance would be greatly appreciated.

Thank you.

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?

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, All of a sudden, I lost absolutely all of my bookmarks. My PC is running Windows 11. My Firefox account was and still is logged in. At first, I thought the data loss was due to a CCleaner cleanup using their latest update. After the data was lost, I tried running another CCleaner cleanup, but this time it didn’t delete the bookmarks. So I honestly have no idea how this could have happened. These were bookmarks I had saved over many years... It’s a disaster.

Moving Firefox over to a new computer, I know how to find the profiles via file manager- that is not my problem. I am not sure which to move, Local or Roaming. I am thinking Roaming as that has all my bookmarks and passwords. I have moved individual files from Roaming and do have bookmarks and passwords working on new computer.

But I was thinking it would be best to move the whole thing so I got the tabs that should be used on startup and maybe more I don't know. So I don't know if I should copy both over or just one. I did try both once and Firefox said it couldn't find profile (I renamed the old ones).

Thinking I may need to use about:profiles and select new one. Not sure what will happen, hope it lets me point to new file on my USB drive. Looks like I should use both local and roaming, but don't know? Local might be something that relates to hardware on computer.

Hope this makes sense?

My laptop's motherboard is being replaced. While that process is ongoing, I'm using a spare laptop from my employer. I didn’t realize that resetting my password would delete all of my saved passwords, bookmarks, etc. Will they still be available on the laptop that’s being repaired, since it wasn’t synced with the Firefox servers?

Firefox tanked everything I had open on my browser including job postings that I was applying to. I can't get them back. I'm so furious beyond belief! Everything I was researching - ALL GONE!!

I accidentally uninstalled firefox and need to recover passwords and bookmarks. Can this be done? I run an old dell latitude with Windows 10 and was trying to cleanup apps running in background at startup since it was running very slowly. At one point I saw 2 firefox icons. Uninstalled one and lost everything. Can you help me. Michael Evans

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
