Firefox Community Forum

Your update has erased every bookmark I had, no gmail, no YT, NOTHING is left. my history is erased. Thank you for destroying my computer. WHY DID YOU DO THIS TO ME?

so, update to 138.0.4 (64-bit) resulted in deletion of both my bookmark library AND all the backups? fantastic. over a decade of important bookmarks - gone. thanks guys, you're awesome.

Last week my (very old) computer crashed and upon restart, Firefox was displaying the attached error image. I uninstalled and reinstalled Firefox several times in an attempt to get it to work but upon re-installation(s) every tab would just say "Your tab crashed". I was receiving the 'Bad Image' error code for Firefox as well as other software such as my pdf reader and iTunes. I took my computer to my local shop where they told me my computer was running out of memory and so they've installed some more as well as upgrading my 8gb RAM to 16gb.

I'm now able to run Firefox again, and my other software, but I've since lost the profile, with my tabs/bookmarks/history all gone. I'm super ADHD and so was very reliant on my bookmarks and my many tabs to organise my life.

I've tried importing old profiles from an 'Old Firefox Data' folder but none of them have my old bookmarks etc. The 'Old Firefox Data' folder seems to be dated after the crash.

I also did not have a Mozilla account at the time of crash. Is it possible for me to recover any of my old profile data? Any help would be greatly appreciated!

As of a few days ago all my bookmarks disappeared and I can't save anything to bookmarks nor can I type a couple letters of frequently used websites and the url automatically comes up. Jenny

I ran into a glitch in another program, and as part of trying to fix it I rebooted my computer. On doing so, I find that the VAST majority of the tabs I had open in my main browsing window have disappeared - some of them out of tab groups I'd created to avoid losing the tabs in question. Neither tab history nor browser history show the missing tabs.

What gives?! Is there any way to restore the window as I had it, say, yesterday?

For the second time, FF opened w/o restoring the previous session's tabs. The first time I was able to restore the tabs. This time I can't. And can't figure out how to fix it or why this is happening since I have the restore previous session box checked.

I have tried every support advice I can find and no matter what I do passwords are not restoring. Here is what I have done: Opened about:profiles Opened profile folder Exit firefox transfer key4.db and signons.jstor files from backup to the new folder

Nothing happens.

I have tried creating new folders and following those steps. I have tried everything.

I accidentally uninstalled firefox and need to recover passwords and bookmarks. Can this be done? I run an old dell latitude with Windows 10 and was trying to cleanup apps running in background at startup since it was running very slowly. At one point I saw 2 firefox icons. Uninstalled one and lost everything. Can you help me. Michael Evans

For some reason, after I had already been using my Firefox account, it would not let me open it up. It said I was trying to use an old version and had to update. So, I did. Then I had to change my password because I could not remember what mine was. Now, I have lost all my bookmarks and stored passwords. How can I recover them?

Greetings

I have recently formatted my disk and installed a new OS. Of course, I have a firefox account which is supposed to sync all of my data. Unfortunately, I used a securely generated password for my firefox account and didn't think about changing the password or saving it to somewhere safe, so I had to reset the password to access the account on my new OS. Now everything is gone, and restoring the bookmarks through the Import and Backup option does not do anything. Is there any way to get my data back, or am I cooked?

Thanks in advance

Yesterday I could access my passwords saved in Firefox, but today there were only two & those were in an open window for passwords. How can I recover my list of passwords, please? I'm using a MacBook Air with an M3 chip, Sequoia 15.3.1 Thanks so much!

Today my Firefox browser updated & all my bookmarks have disappeared. In place of my Bookmark toolbar is just "For quick access, placeyour bookmarks here on the bookmarks toolbar. Manage bookmarks(link). The bookmarks side bar is empty. I've followed the instructions to try to recover them but the page(Goes there from the "Manage Bookmarks" link) they send me to has no functionality. Whatever I enter goes nowhere, whatever I select. I've tried several different routes from the support/help pages to resolve but always end up at this dumb page.

How do I get my bookmarks back when the tools to do so don't seem to want to work?
