Firefox on desktop crashed. When it crashed, it deleted the Google email account I use to login for many sites. When I tried to retrieve that account, Google responded that it is deleted and the name cannot be reused.

Is there any way to resurrect a session from, say, 5 hours ago.

I opened firefox this morning on my laptop and it froze and shut down. When I opened firefox again it opened as a new window and all of my tabs and tab groups were gone. They do not show up in my history or recently closed tabs. Previous session is shown as current session so no option to restore.

Is there any other way to get these back?

I've tried to import bookmarks from an export file created on another computer but Firefox says there are no bookmarks in the file -- clearly wrong since I see them and can click on them to go that site in Firefox.

I've also tried to restore them from Old Firefox Data but Firefox won't read those files either.

COPIED FIREFOX BOOKMARKS FROM MY HP COMPUTER TO MY DELL LAPTOP BY COPING THE HTML FILE OF BOOKMARKS TO MY DELL LAPTOP DESKTOP SCREEN AND IMPORTED THEM FROM THE DELL LAPTOP DESKTOP AS ADVISED. STILL DID NOT GET ANYTHING COPIED TO THE NEW FIREFOX INSTALLATION EVEN THOUGH IT STATED IT HAD COPIED 827 BOOKMARKS. NOTICED THAT THE FIREFOX SOFTWARE INSTALLED ON MY HP COMPUTER STATED THAT IT WAS WINDOWS 10 INSTALLATION. ORIGINALLY THE HP WAS WINDOWS 10 BUT UPGRADED IT WITH FREE MICROSOFT WINDOWS 11 BUT DID NOT UNINSTALL FIREFOX FROM IT AND REINSTALL FIREFOX AFTER THAT. THEREFORE THE FIREFOX BOOKMARKS ARE FOR A WINDOWS 10 INSTALL ON THE HP COMPUTER AND TECHNICALLY NOT A WINDOWS 11 EVEN THOUGH THE WINDOWS OS HAD BEEN UPGRADED TO WINDOWS 11. SO, I GUESS TO PERFORM THE ACTION I STATED ABOVE TO UNINSTALL FIREFOX ON THE HP COMPUTER AND REINSTALL IT ON THE HP COMPUTER IT IN ORDER TO GET IT TO WINDOWS 11 FOR BOOKMARKS? HOPEFULLY I WON'T LOSE THOSE FIREFOX BOOKMARKS?

I’ve been using Firefox for months without manually creating a profile (I assume one is created by default). I had a lot of bookmarks, and today I accidentally created a profile manually, but then deleted it after noticing it didn’t have my bookmarks. Now, even after deleting it, I still don’t have my bookmarks, and Firefox keeps creating profiles for me. I checked backup files, but I can’t find anything, or maybe I don’t even know which folder I’m supposed to look in. My browsing history is gone, and I think I also lost my saved passwords or usernames for websites I used.

I’ve already tried using firefox.exe -P and checking %appdata%\Mozilla\Firefox\Profiles\, but my bookmarks aren’t in either of those folders (.default or .default-release). Honestly, I really don’t want to believe I could have lost everything that easily.

I even used Recuva to try recovering files like places.sqlite and checked the bookmarks folders in the only two directories where those files existed, but it was pointless. Honestly, I still don’t even understand how everything got deleted just from manually creating a profile. I really didn’t expect something like this to happen.

I need my original Firefox account back the way it was. I have no bookmarks, no open page when Firefox opens, and none of my tabs are the same. Please put it back; I don't know how to run my computer this way.

Hello Mozilla Team,

I'll directly jump into - 12 years of Bookmarks and history are gone after the last update. No warning or anything. Can you help me restore? That's unbelievable.

Firefox just updated to version 157.0 and now all of my bookmarks are gone. I export my bookmarks but even when I go to Manage my Bookmarks and try to import the file I saved, clicking Browse button doesn't do anything. What happened to my bookmarks?

Honestly, I don't know that "topic" best describes my situation. I am not a "techy" and should not be required to be a "techy" to be able to use Firefox and have it not create terrible problems for me.

Where did my favorites and extensions and homepage go? I clicked "refresh" since you, Firefox, RECOMMENDED THAT I CLICK "REFRESH," and

EVERYTHING IS GONE.

Where is EVERYTHING? I cannot get it back and do not have anything saved. I trusted you. There is no Firefox folder saved to my desktop. There is NOTHING. I have simply lost about 50 FAVORITES PAGES that I NEEDED.

This is disgusting and a betrayal. Firefox? Never again.

Hello,

I keep running into an issue where my group of saved tabs disappears.

I will make several groups of tabs. When I right-click and press "save and close group," to shut down my laptop completely. There are many times when I return and try to access the saved group of tabs using the drop-down arrow at the top of the browser; all the saved groups will be gone.

Normally, I find them under "Recent Tab Groups". There have been many times when they are completely gone. Is there another way to find these groups of tabs or are they disappearing completely are a certain amount of time has passed?

Thank you,

Hello,

Several passwords were saved by Firefox. They are only saved locally ( no sync with Mozilla account). I recently upgraded my laptop from Windows 10 to Windows 11. Since the upgrade, no password is available in "Saved Password" section. I checked my profile and I can find logins.json file ( with all encypted logins and passwords) and key4.db file. I suppose my passwords cannot be decrypted as they were encrypted with Windows 10.

Is there a way to recover my passwords?
