Firefox Community Forum

The launch of Firefox Profiles seems to have obliterated everything in my account: bookmarks, history, open tabs, and extensions are all gone completely. I have an option to import files from another browser, but not from my own past firefox. I logged into my Mozilla account, but I didn't have any other devices so I think it was still unable to recover the data? Is there anything I can do about this, or is all of my data truly gone?

I posted a question in here two days ago because my firefox wouldnt open anymore i got a follow up answer telling me to give the crash id but never got a follow up after i sent it . i tried shuffling between profiles and in the end got it working but today my pc had a crash while firefox was open and it had to restart when i tried to open firefox its as if i just installed it and i dont have any backups to be honest i tried checking the appdata folder and there is a profile folder that seems big enough that it might be mine but it doesnt seem like firefox is reading it for some reason i tried switching the data in the profile folder that firefox is considering but it didnt work .

There was a issue with my computer due to which I had to reset the unit and once the reset was completed I'm unable to recover my data as its asking for 32 account recovery key, I'm unable to find that key anywhere and need help where can i find the key as there are important bookmarks which I need back.

Mozillers,

I depend heavily in my environmental and other work on Firefox and am grateful for its ability to restore previous tabs when my laptop, not infrequently, stops working abruptly.

Now the much-used bookmarks have disappeared. A search site states promisingly:

"To restore Firefox bookmarks, use the built-in backup feature by going to Menu > Bookmarks > Manage Bookmarks > Import & Backup > Restore, then select a dated backup or a manual file (like a JSON backup) to bring back lost bookmarks..."

But my Firefox's Bookmarks drop-down menu has no Manage Bookmarks option. PLEASE, what must I do?

Elsewhere I managed to find this file which apparently contains recent bookmarks:

"C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\unk14jlv.default-release-1647366062305\bookmarkbackups\bookmarks-2025-12-26_95_4IdGtYxezJpwuH1UIiT1bRwe1K6bcGO8rv0mqa9rUWU=.jsonlz4"

But attempting to open it with Applications\firefox.exe (default) accomplishes nothing.

FOOL-proof instructions would be wonderful. Thank you.

Hi. I accidentally deleted the "Today" subfolder that exists under the "History" section in Mozilla. How can I get it back? I'm not interested in getting the internet history from today back, just the folder. Thank you for your help.

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

I still have not made any progress recovering my lost Firefox bookmarks. I have tried several methods with no success. The bookmark toolbar doesn't work, so I can't bookmark any more pages. I tried restarting the computer and Firefox to no avail. I am considering switching to another browser. I am using Duck Duck Go which is not as good as Firefox that I have been using for about the last 10 years. I might try Microsoft Edge or Bing or some other browser.

Sincerely

Hello! I accidentally logged into my account after switching to a new computer, creating a new recovery key. Now i do not have access to all my saved passwords. I have my recovery key but cannot find where should I type it to get back all my information. Is it possible to recover my information using the original recovery key, not the one I accidentally created? I really need to get the access to all my saved passwords, please help me with it. Thank you!

My previous post seems to have disappeared, so will try again. I am 85 years old and have been using Thunderbird fo over 15 years with out any problems. Afew days ago I tried to send an e-mail and didn't have any "Send" button. In trying fix, I some how deleted my contacts sidebar. I sill have my addresses book. I have tried everything to retrieve them but no luck. I tried removing Thunderbird and reinstall, but it comes back the same. I would appreciate an guidance in trying to resolve my problem. Thank You

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

Siguiendo sus instrucciones facilitadas, he conseguido recuperar la carpeta de mi perfil anterior pero no se qué hacer con ella para que aparezcan los marcadores de siempre en la aplicación, cómo lograrlo Gracias

I have enabled the option to open the previous windows and tabs. I had one window that I always closed last as it had a lot of groups that are important for my work, so it used to open every time I started Firefox. Sometimes, even if I closed the window by mistake without closing other windows, I was able to get it back by pressing ctrl+shift+n.

But yesterday, I might have closed it by mistake and when I pressed ctrl+shift+n , it didn't come back. I wasn't able to access my window and now it's all gone. I don't see anything in recently closed windows in history.

I need those tabs back as they are very important for my work. they were a lot of tabs. I had many groups but now all are gone. I tried by using the previous.jsonlz4 in the sessionstore-backup by renaming it in the default-release profile as sesstionstore.jsonlz4 but still wasn't able to access my window.

I didn't clear my history as the tabs opened in the window still show up in the history.

Kindly help as soon as possible

w11 on laptop. Cleaned PC using CCleaner. Restarted windows. Launched Firefox and only 1 tab with calendar opened. Went to History but no indication of the previous session available. ?
