For the third month in a row every, EVERY!!!, password I have saved to my Firefox browser have disappeared. Poof, GONE! For as long as I've used Firefox, 10-15 years, it had never happened before September of 25 Some of these password, prior to September, I'd had for years. Yes, I know I should change them over time, but I haven't. How do i recover them? I'm really Pi---d off. Help!

After updating to the new version all of my open tabs & Bookmarks have disappeared with no option to recover. Additionally, all of my saved passwords for the various tabs I use daily no longer auto-generate with just a couple of clicks of the mouse.

I recently bought an new HP Win 11 PC to replace my current Win 10 machine. Running latest FF 144.0.2 on both. How do I transfer my complete FF profile (bookmarks, bookmark bar, login data, EVERYTHING) to the new PC? Want the new install to be an exact functional copy.

THANKS!

When I started my browser today, my history and bookmarks were gone. When I try to restore them from the backup file, I cannot click on any buttons in the Manage Bookmarks folder. The buttons are entirely unresponsive.

Why did I have to change my profile. I am afraid that now I have lost the password and bookmark library I have spent years building. Why? If I have lost everything I am dumping Firefox forever. This sucks!

Good afternoon

Copied Firefox profile in W10

Pasting into Profiles folder in W11 but it won't let me do it. See attached.

I have enabled LongPaths in the registry but that hasn't solved the problem.

Please advise Michael

I have purchased a new computer and I want ot transfer al my bookmarks, login details etc onto the new one. I have followed the instructions given on your help pages, to no effect. My old computer ruins Firefox under Win 10. The new computer runs the same version under Win 11. I have copied the contents of Profiles from the old to the new, but Firefox says the profile is missing. When I copy and add the folders in Profiles to the Win 11 computer, there is no difference. The names of the folders in Profiles are different on each computer, so I think that it is looking for a particular file/folder name, but I don't know which one. Can anyone help me?

why can't I restore bookmarks. All solutions will not work "unable to process file". This happen mid secession.The restore dates are there but i get unable to precess file

I'm running win11 25h2 with all updates done both chrome & edge are not causing issues

Hello ~ Re. On Macbook Pro, I messed up all sessionstore folders and files.

After a recent Firefox crash (maybe due to repeated bad connections and using a VPV in China), I lost all my previous tabs (more than 100) and I also didn't see the "Restore previous session" in History. 

I was able to find 'previous.jsonlz4' (and other *.jsonlz4) files on my October 11 Time Machine backup. However, after replacing, renaming, deleting various *.jsonlz4 files, Firefox, after reopening it, disregards any changes (deletions or new tabs) i made on the my last session, and return to the October 11 situation. I know i messed things up (see attached screenshot), but how can i clean that mess?

Thanks, Amos

Hello -

My bookmarks (400+) that I have accumulated over several years were all gone when I signed into my computer recently. I tried to restore them, but I was unable to get them back from all of the 15 backup points. I kept getting an "unable to process backup folder" error message. I only have one Firefox profile that I am currently signed into.

I use CC cleaner to clean my computer weekly and sometimes use the custom clean feature to clean up cookies and browsing history, but by default the clean bookmark backups box is unchecked and I have never had a problem using it before. I suppose it's possible that I may have checked that box, but I don't know if that would have also wiped the bookmarks off my browser. I am also checking with CC tech support to see if they have any answers. Suppose I may be out of luck if so.

I also sometimes go into FF settings and clear browsing history and cookies, but I don't think there's even an option to wipe out all bookmarks. I have also been doing that for years, and have never had an issue before. Does anyone know if there's a way to re-download my bookmarks from the cloud, or do I have to start all over again?

Any tips would be appreciated, thanks.

Hello, All bookmarks disappeared after last update on Sunday 11.2.25. Is there a way to search some files and recover them? This is currently a big problem for me as all bookmark are related to our business.
