Firefox Community Forum

I put my computer to sleep last night. Woke it up this morning and all of my bookmarks are gone. When I click on accounts, it says account disconnected. How can I get my account reconnected and get all of my bookmarks back because I do not remember all of the bookmarks I had.

After an unwanted and un-needed update, all my tabs closed and I can't find them again. Then after rolling the browser back to a previous version, now all of my bookmarks are gone. I want them back where are they on the hard drive.

Hello, all my bookmarks have disappeared since installing the Firefox VPN. How can I recover them? Thank you for your help. Operating system: Windows 10 Pro Regards.

What the fuck did you do!!! your last update wiped out all my bookmarks for all my work and everything. who thought that was a GREAT IDEA should be fired!!!! What the fuck do I have to do to get them back and thank you for fucking up my life.

Is there any way to reopen the tabs from that missing window? "Recently closed windows" only shows the last 3 tabs in that window. I've tried restarting Firefox 3-4 times, and rebooted my Mac, with no success. The reason I originally restarted Firefox is because it was suddenly working very slowly. The window that did open has about 30 tabs; the one that didn't open only had about 15 tabs.

I have recently purchased a new Windows 11 computer, and want to install Firefox there and transfer all my bookmarks, passwords, etc. There are obviously quite a few Support articles on this topic, and seemingly quite a few methods to use: copy and paste profile folder, sync, the backup/restore function within Settings, etc. I'm a bit reluctant to use sync, as some users report it can be an incomplete transfer. My current profile also may contain some "corruption", so I'm reluctant to copy the entire profile folder to the new computer.

Comments by esteemed and superb contributor cor-el in this Support article: [https://support.mozilla.org/en-US/que.../1454070] therefore may be my best option. He wrote:

Note that best is to avoid restoring a full profile folder and only restore important files that are safe to restore/transfer.

   bookmarks and history: places.sqlite
   favicons: favicons.sqlite
   bookmark backups: compressed .jsonlz4 JSON backups in the bookmarkbackups folder
   cookies.sqlite for the Cookies
   formhistory.sqlite for saved autocomplete Form Data
   logins.json (encrypted logins) and key4.db (encryption key/primary password) for logins saved in the Password Manager
   cert9.db for certificates stored in the Certificate Manager
   persdict.dat for words added to the spell checker dictionary
   permissions.sqlite for Permissions and possibly content-prefs.sqlite for other website specific data (Site Preferences)
   sessionstore.jsonlz4 for open tabs and pinned tabs (see also the sessionstore-backups folder) 

My questions are: 1. Why is it "best is to avoid restoring a full profile folder"? 2. Is this the complete list of "important files that are safe to restore/transfer"? 2. In my profile folder, there are several files that start with the same file name, but then have different file extensions. For example: cookies.sqlite, cookies.sqlite.bak, cookies.sqlite-shm, cookies.sqlite-wal. Should I restore ALL these files, or just "cookies.sqlite"? 3. Is the correct procedure to copy the selected files from the "old" profile, and then paste them to the "new" profile, which presumably would overwrite files of the same name in the "new" profile? Thanks!

Why has the most recent upgrade to Firefos removed ALL of my tabs and pinned tabs? I have lost loads of pages that were important. I can see some of them in the history BUT I am unable to 'reopen all tabs' because that facility doesn't work! It's a disaster.

Hello, I'm wondering if someone help me troubleshoot why the normal or recommended password files recovery isn't working in my case, because it isn't. I've spent 2-3 hrs this evening trying to follow the normal/recommended protocol for recovering previous passwords but it's just leading me in circles, sans passwords being recovered. What usually happens is every couple years either my bookmarks file gets completely lost or - this is new - in this case my saved passwords are gone (possibly corrupted, I'm not sure). I think something might've been corrupted or reconfigured (I hope not "lost" entirely), attempting to install and use the Beta VPN. Ultimately it was just too difficult to get it to work simultaneously around Norton360, which I decided was probably better to just stick with for now. Out of curiosity, I was attempting to get the Firefox Beta VPN installed last night (and operational) and I think that may have been when the previous data was lost or reset somehow. I tried following the basic procedure to reboot FF from previous folder backup (to desktop, "Old Firefox Data"), but that merely reproduces the same "empty" passwords page when I try to open up my saved passwords. Neither of the 2 previous App Data locations seem to help rebooting from ("default" or "default release"), and I'm hoping against hope, at this point, that one of those old JSON files has all my passwords still in it, uncorrupted, but there are so many, I have no idea how to find my way to the correct one. In any case, my FF saved passwords were still fully available and working as of only a few days ago, probably this last Sunday evening, today is Wednesday of the following week. My previous saved Bookmarks are apparently still intact, and auto-loading as normal, regardless of which of the previous user profiles I'm rebooting FF with. If anyone can help me, I would really appreciate it.

Hello,

My Firefox app was crashing, so I turned off my computer. When I turned it on, Firefox was completely reset: no profile, app initialization... I also cannot find my profile into my files.

Could you help me please ?

Today I was prompted to restart Firefox. When I did, I got a homepage that said "Congratulations on 150 versions of Firefox" or something like that. Then I shut my computer down. When I booted it back up, ALL of my profiles, bookmarks and web history are gone. I can't find anything on my desktop to "restore" my old settings. I'm prompted to "create new" profiles. WTF is going on?!?!

bold textWhen I opened my computer this morning without warning the Firefox had a new default page and all my information was gone. I've tried deleting and redownloading and trying to follow the instructions on how to transfer the information, I could not get anything to work. I know I'm doing something wrong but have no ideas what I am suppose to do. Very disappointed I had some importat information on the desktop and would like to get it back.

My imac late 2015 running 10.12.6 Sierra crashed yesterday and on rebooting I noticed that my Firefox browser had disappeared. I was asked to reinstall with a new Extended support Release 115.34.1esr which I did but now I have lost all my bookmarks and access to my Outlook account. Is there a way that i can retrieve the lost settings?

I am unable to view my extensive bookmark list, which I have always accessed by clicking on the star button in the left margin of my screen. They suddenly disappeared yesterday.

FireFox browser closed and when I opened it all my bookmarks are gone, all of my history is gone everything is gone as though I never ever used firefox in my life.

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?
