• Old laptop can no longer access the internet; corrupt Windows 10. Bought a new HP laptop. Have Sync turned on on both laptops but am not getting any favorites, passwords that I desperately need. What are my options given the old laptop can't connect.

My SSD boot drive crashed -- Rebuilt system (brand new SSD boot drive) and reloaded all of my data from a separate backup, however Firefox profile is gone. I have copies of the old profiles including the places files, etc. Following Mozilla's instructions I reloaded the old profiles. Firefox starts right up but *without* my bookmarks, etc. Unfortunately there was no "old Firefox data" folder saved and I could not retrieve the bookmark specific backup. Thoughts? Thanks!

I only have one profile, the default one , I clicked something ; Firefox closed and when I opened it again I had to create a profile again , and everything I had, bookmarks history, was lost . How can I recover it , or go back to the first default profile, why is it even possible to exit firefox in any way and not be able to go back where you were.

Bookmarks in Firefox disappeared and cannot import my Bookmarks backup. I have tried to restore an older Bookmark file through /manage bookmarks/ import and backup/restore to no avail. thank you

This isn't exactly something that is broken but it is something that is plenty weird and I wondered if anyone has an idea how it happens.

I shut down my Linux laptop one day and when I started it the next day, all my tabs were gone. Annoying, but I spent some time searching for the most important ones and got on with my life.

We have a class picture book that is only accessible by faculty from campus or using the secure VPN. It helps us to learn people's names. It is an HTML file. One day, I needed to look someone up. Ordinarily that would open a new tab in the browser I have running, but it didn't. A whole new Firefox appeared for it and there were all my lost tabs.

Wut?

Now I can use the picture book to alternate between my old tabs and my new ones. How on Earth can this happen? It isn't exactly something that is broken, just something I don't understand.

I seem to have lost all of my bookmarks & i have tried to Import and backup / restore in manage bookmarks tab but all i get is a message "unable to process the backup file" plus when i tried to bookmark a web page by clicking on the Star bookmark icon nothing happens now for some reason. Was there an update as this only just started around 2 days ago

cleaning up my computer, I accidentally deleted firefox. I had a list of favourite links, and I lost them. Is there any way of recovering my list of favourites?

thank you, Glen A Goodale, [email removed]@gmail.com

Stupid mistakes were made - I reinstallted windows and when I opened firefox I realized, that I did not know my password and also was not sure about the mailadress. I finally found an account with my mailadress but reset the password - it said that all data in the account will be deleted if I do that.

I got the old files recovered, but everytime I copy paste the old key4, login and cert file... nothing changes withing the browser. If I copy the whole old profile folder and exchange it with the new one and then I open firefox it just says "profile could not be found" and then firefox closes.

Is there any chance of recovering my old saved passwords or did I screw up entirely ?

I powered up my MacBook the other day, and Firefox updated. Then, suddenly, all my bookmarks and history were gone. I have tried the "about:Profiles" and nothing is there. I have read here that many with OS have encountered the same issue.

What is the fix?

Hey guys, My friend got on my pc and shut it off without me looking and somehow when i opened it back up all my tabs(couple hundred) distributed between 3 windows were lost. I've tried all the usual recovery options by doing previous or session restore, its not popping up in recently closed windows as well, where i usually recover my sessions from if it does go wrong. Is there any other way where this data may be stored, to recover a session from 31st Dec 2025.

Would greatly appreciate any help :D
