Firefox Support Forum

I had a crash on my SSD (WIn7 Ultimate) - " Operating system missing" error. I saved the data and want to reinstall Win 7 and import previous Bookmarks data to new install of Moziilla Firefox.

I transferred the sqlite file (s88qn337.default) from the previous install (now non working system) to the existing working Firefox directory (C:/Users/My Name/AppData/Roaming/Firefox/Profiles/xxx.default.

I then renamed "default.XXX.old" (the previous install had only one file in the Profile directory - ie s88qn337.default)

When I try to open Mozilla Firefox, with the single file (s88qn337.default) in the Profile directory, I get the error "Can't find user data".

When I then open fresh install of Mozilla Firefox on working SSD (Win 7 Ultimate) and try to Import Bookmarks, the options are only "Import Bookmarks from Explorer" or "Import from html file".

How to resolve this problem, please?

Why is Firefox backing up my bookmarks in a json file, when Firefox itself doesn't recognise the file type when trying to restore said bookmarks? I WAS able to restore my bookmarks by converting the json file at https://www.jeffersonscher.com/ffu/bookbackreader.html. But why can't Firefox just back up as an html file like it used to? I had to go off searching the internet for a solution, turning what should've been a 5 minute job into nearly an hour 😕

Hello, I'm running FF 124.0.2 64 but in Win 10 on a PC. I have the bookmarks right across the top of the page; the sixth from the left at the moment is Seloger's website. If I have a tab open looking at a TV program website and right click on a link to see more details in a new tab, the new tab opens ok, but the TV program website is overwritten by the Seloger's website. If I use the "previous" arrows, it reverts to the TV program site. If I change the order of the bookmarks across the page, the TV program website will be overwritten by the bookmark then in the sixth from left position. This is driving me mad. How can I force FF to stay with the open tab and not change it by itself?

When I opened Firefox web browser it did an update today, and since then I cannot find my bookmarks, sign ins or passwords. I need help here and I am not very tech savvy at over 72 years old.

previously I added bookmarks to a menu bar at top of firefox. Now I have a bar that displays 2 bookmarks than a >>. I cannot expand this limited display or create a menu to display bookmarks though I can see them by clicking on the >>. Non of the menu suggestions is a fix.

Does anyone know how to control this and get me a more useful bookmarks menu display?

After restarting Firefox i found I've lost all History and Bookmarks.

I tried simply restarting computer and everything on here: https://support.mozilla.org/en-US/questions/1408758

I'm on a MAC, I'm not sure to do at this point, I had atleast 10 years of bookmarks!

let me know if there's any other solutions thx

When I use 'Manage Bookmarks' and the Library to delete bookmarks and bookmark folders in addition to cleaning up duplicate bookmarks, the deleted folders and bookmarks automatically reappear in my Bookmark sidebar 1-2 hours later.

Initially, I had sync on but did not have Bookmarks checked for syncing. Deleted bookmarks and folders still reappeared. Then I turned off sync for this browser / machine. Deleted bookmarks and folders still reappeared.

I tried to see if there was a setting that enabled automatic restores of bookmark backups - but could not find one to turn off. I have tried refreshing the installation and starting again - using a one-time sync from another machine - but continue to be unable to permanently delete old / obsolete / duplicate bookmarks and folders.

I've also tried 2 Bookmark clean-up extensions. While I am able to delete duplicates and empty folders using these tools, 1-2 hours later they are back in the Bookmark sidebar.

Is there anyway to prevent the automatic restoration of the Bookmark Library?

Thank you

As of today 5/20/2024 Firefox stopped saving bookmarks. The star turns blue to indicate the bookmark was saved, but when I check the folder in Bookmarks it's not there.

I have to install firefox new everyday on a library computer, (short answer mine was stolen and I can't replace it for now).

Anyway used to have no problem I would go in install firefox sign in and my bookmarks were repopulated. Today I installed firefox and nothing. No bookmarks, no add ons nothing its like a blank install with new profile.

I do not have a backup saved profile on this computer as it is a virtual machine and each day when it shuts down it wipes the programs and data installed. Because firefox repopulated the bookmarks each day when I re-installed it I was not aware I needed to create my own backup I assumed that it was just something in firefox that worked well and another reason why I prefere to use it.

Until today it was not an issue once I signed in everything would re appear but today its all gone. Is there anyway to recover this as it is very important that I do. I use these bookmarks a lot.

I have many rare bookmarks. This time I sell my old laptop and rent another laptop. The laptop rental a strange windows version (probably a hack one) and some strange apps (like 360 what what), I uninstalled the 360 what what apps. Then I downloaded and installed firefox and open all bookmarks become 365whatwhat. I did not care it so much, I logged in my firefox account, but the bookmarks did not change! I click sync, all the bookmarks are still 365 or 360 whatwhat. All my previous bookmarks are lost. How to recover?
