Had a crash earlier on my macbook that required a restart. Everything else is fine but I have lost all history and bookmark data on my firefox browser. I tried going to see if i had the wrong profile and that was not the issue. I tired recovering the bookmarks in the manage boomarks option but there were no backup files.

I have some important bookmarks i need recovered. Any help would be highly appreciated.

While launching Firefox VPN browser all of my bookmarks were erased. Additionally, my backup copy of my bookmark records was also deleted. I have not been able to reboot or restore the system. I need help.

So far hate new Firefox that I have been forced to switch to - very annoying and such a waste of my time trying to sort out my bookmarks. May make me switch to Edge or something.

Followed the instructions - C:\Users\name\AppData\Roaming\Mozilla\Firefox\Profiles\ - found a backup but no information as to how to get the bookmarks into the new Firefox?????

Many of us are older users and perhaps not so savvy as to how to do this.

And so it would have been nice if Firefox could have been more "nice and be specific" with this forced change over.

Thank you

Since Firefox automatically updated (14.0.1) on my MacBook Air (2025 model) several weeks ago, the Bookmarks and History functions haven't worked. Can anyone suggest how I can fix this?

I deleted my history and it also deleted all my information. I cannot sign into any thing because it is not sending the code to my phone. Even on other browser I cannot get any infomation because the code is not being sent go my phone and I cannot use my email because I cannot get a code to open it. Please Help.

Firefox crashed and now my shortcuts have gone and the bookmarks are not easily accessible. I tried importing from the desktop but they are now in a long list and not as they were (in the toolbar. I can't gt the "bookmark summary" showing in the toolbar area.

Firefox prompted me to update, I hit download, my entire PC froze, I restarted the computer, when I opened firefox again and hit "restore session" it restored a session that I had opened months ago. When I checked my history, everything after that older session had been deleted. All of my history from the past few months has been deleted. I tried a few different solutions from trying to research the problem, nothing so far has worked. The only thing I have found is a session restore error saying "could not decompress file", but I could not find the file it was attempting to decompress. This is the error message I found.

Any help is greatly appreciated. I'm one of those people that tends to have way too many tabs open at once due to poor memory, and losing months of tabs and progress is a huge setback. I'm very desperate to get the history and tabs back.

The method of putting an older jsonlz4 and naming it sessionstore. It's not working. I've also tried session history scrounger and it's just saying "session history file contents couldn't be read". Any ideas, I've lost a LOT of tabs to it forgetting the previous session.

I've tried all files from the session backup folder including the update backups and I used shadowexplorer to get my session files from the 18th.

Hi, I recently purchased a new laptop and want to bring over the bookmarks I had from my old laptop. I had copied what I thought was the profile from the old one and copied it into the new laptop - but I'm not sure of the next steps :(.

I accidentally refreshed Firefox when I was having problems and didn't realize Refresh meant wiping everything clean. I found another thread about this, but it's 8 years old and things have changed. How do I use the "Old Firefox" folder on my desktop to restore all my bookmarks, history, etc.?

I need a way to recover open tabs, history and bookmarks when firefox crashed. I type placessql and session in firefox profiles folder and nothing comes up. Firefox won't open at all and I asume if I reinstall it I'll lose all previous sessions. What files I need to copy before reinstalling?

Mozilla usually doesn’t restore all the windows I’m working in; when I open it, it only restores a few of them. I usually use the ‘History’ > ‘Recently Closed’ > ‘Reopen All Windows’ option, but this time not all the windows I need are being restored. My most important window, containing 1,000 essential tabs for various articles, hasn’t been restored, and it seems as though I have absolutely no chance of finding it at all; I don’t even have a ‘Restore previous sessions’ button. I don’t know how to get that window back, because restoring the tabs one by one would take an age and I’d probably lose a lot of them (it’s very important that these were tabs, not bookmarks). What should I do?
