I updated Firefox for my laptop this afternoon and another Firefox window opened and I had 2 windows. I closed the original window. I tried to restore my tabs and bookmarks in the new window. My Recently Closed Tabs and Recently Closed Windows are greyed out in the "hamburger"menu. I have tried everything; trying to restore from my profiles folder on my laptop, trying about:session and at this point I am Totally lost and frustrated. I am asking for help :-) please to have what I had before. Thank you

Firefox desktop (147) keeps deleting all Bookmarks, passwords and cookies. I sign in and it's fine till I restart windows 11, then all is gone except the titles of the Bookmarks minus ANY data they may have held. Importing B.M.'s works till the process starts again. Cookies are just gone and same with any passwords I may have saved. just seems to happen in Firefox, was never a problem before the end of last DEC.

As the title states, every time I restart my PC, Firefox deletes everything. Bookmarks, passwords, profiles, all of it. I'm really tired of having to hunt down backups and restoring/creating new profiles constantly. Is there any fix? I really like Firefox but if there isn't a fix I'll look into a different browser.

I just moved to a new Windows 11 PC from my Windows 10 PC. I backed up my Firefox profile and put it on a portable drive. I loaded Firefox on the new PC and then found the folder where the profiles are. I added the profile folder from the backup. Firefox has not found it and there is no way I've been able to discern to search for it.

I added the anti-virus after trying to set up Firefox.

Here are the particulars: Firefox version 146.0.1 (64-bit) Windows 11 Application Binary: C:\Program Files\Mozilla Firefox\firefox.exe Profile folder: C:\Users\xxxx\AppData\Roaming\Mozilla\Firefox\Profiles\xxxx.default-release

Any help appreciated.

I use Firefox every day and have since the browser's very early days. I have a Firefox account, and am logged in when using it.

Typically, I have some pinned tabs (calendar, for instance) and also some tab groups (Container Tabs). There are usually a small number of open tabs. For example, this week, I have been googling spreadsheet formulas for a Google Sheet I am working on.

Occasionally, perhaps once every couple of months. when I open the browser, everything is gone. All the pinned tabs, tab groups, and the tabs I'd left open deliberately are not there. Just one tab (Google), is open.

I can re-open the container tabs and add them to the tab bar again, try and remember which tabs were pinned and redo those, but having to trawl through history to find the very detailed searches for spreadsheet formulas and work-rounds - is all very tedious and shouldn't be happening!

It has only been happening for at most a year, maybe seven or eight times in total, but those seven or eight times shouldn't happen.

I have searched for a way to restore it to how it was the last time I closed it, but cannot find any way to restore Firefox to how it had been.

I am using an a fairly new ASUS laptop (but it happened on my previous PC too), with Windows 11 installed and up-to-date. Firefox is always kept up-to-date too.

Any suggestions would be very welcome.

Hi Due to a corrupted profile following a Windows 10 to Windows 11 upgrade, I have had to get my laptop reset at a computer service business. They required copying everything off, clearing the hard drive and reinstalling everything. Mozilla Firefox was my default browser prior to this having to be done, however, Firefox was not reinstalled. I have just done that myself. Is it possible to recover the bookmarks I had previously saved to my old Firefox programme? Thank you in advance Gordon Carter

No bookmarks, says in use by another application. Tried all troubleshooting ideas Can't change name or delete places or favicons - again says in use by another application. Disabled all add-on security.

when i restarted firefox as requested, bookmarks displayed across top of screen were gone. the suggested fix was no help. Said cause was a FF file was in use. It implies i have Win10. I have Win11. **************

I need a more permanent fix to the disappearing bookmarks issue when the file is in use by another entity. I have tried to fix it, read the instructions and when I start to apply the fix, the instructions disappear and now I have to depend on my faulty memory.

I have suddenly lost all my firefox data today.. after creating a new browser profile? I never bothered creating profiles and stuff when the update for that came and it seemed like Mozilla never forced me to create named profiles until today when I open it again after booting up and it suddenly asks me to make a profile for the browser and after I did I just saw that I lost everything, I have a firefox account that's sync to my mobile phone but I can't seem to sync it neither, my browsing history, bookmarks, and passwords are all gone and I've even checked the AppData/Roaming/Mozilla/Firefox folder for it and even the recycle bin but I can't seem to find a single trace of my data before firefox forced me to create a browsing profile for my computer. Hoping someone has a solution to this.

All of my bookmarks disappeared. I have followed all the step to restore from the profile folder and to restore manually. It works to a point, then I get an error message saying Firefox is unable to process the backup file (see attached image). I even tried it in Troubleshooting mode.

Yesterday, I lost most of my bookmarks in several Bookmarks folders. These are critical to my work with several non-profit organizations. All efforts to follow Mozilla's troubleshooting advice and use the Manage Bookmarks functions to restore or import backups in my Profiles folders are met with the "Unable to process the backup file." message. I have a number of backups available, any of which could potentially resolve this issue, but nothing I have tried is working. Please help! Thanks, Shack

A couple of updates ago, I received the message that some of my bookmarks will not be available. So I ran through the trouble shooting FAQs and I ran into a problem. When I go into Manage Bookmarks and it brings up my now empty library, when I select Import/Backup then Restore, it will not show me any files to restore from. Additionally, I used Fx File Utilities and it show the corrupt entry that I cannot remove, but allows me to export the json file to an html file so I can import it, but once again, when I select Import from HTML, it shows me no available files to restore from. Lastly, I imported the html file in to Chrome and then tried the option to import from another browser, but again, it will not allow me to select anything.

I have confirmed the integrity of the db as instructed, etc. So I have run out of options. How can I get my 15+ years of bookmarks back?
