Firefox Community Forum

I am looking to Restore yesterday Firefox have lost all my pin tabs when I opened this morning the browser how can I get my old stuff back? Please help me out. Thanks

Mozilla, in their infinite wisdom, sent me a note about something new in firefox, by displaying it in a new instance of Firefox.

It wasn’t until I closed my normal session, that I realised a new instance of firefox was also running, and shut it down on.

In shutting the new instance down after my usual session, it overwrote all my normal tab settings🤬

Q1. Are my normal tab settings recoverable? Q2. Why did Mozilla think it a good idea to open a new instance of Firefox to send me information, rather than simply open a new tab.

NB This is in Windows 11

Due to an internet outage, I got forcibly signed out of my Firefox account. I signed back in, but all my login info and passwords are just gone. I still have my browser history, and I'm even still logged in to some of my accounts, so I know some of my cookies and cache are intact.

OMG someone please help me...I have used Firefox forever as my work browser. I have saved passwords to client accounts for 3rd party sites, etc. It has EVERYTHING. I updated my Mac with the latest software install today and when I opened Firefox it didn't restore my tabs. I got stuck in a loop where it would not update to the current version of Firefox. I uninstalled Firefox and re-installed it and LOST EVERYTHING. I AM FREAKING OUT because all my bookmarks are lost and I don't even know what they are - I have tried to restore bookmarks and it goes back to 2022 and 2023 and when I restore nothing happens. ANYONE SOMEONE please tell me you know how to help me find my stuff otherwise I am cooked.

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 .

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?

After the latest Firefox update I've been unable to bring up all the bookmarks I had. I also lost bookmarks on Toolbar. I've followed posted recovery suggestions but haven't had any success retrieving bookmarks. Has this happened to anyone else? What do I do?

After the update, a window popped up asking me to select a profile. But my profile, where all my passwords, bookmarks, etc. were, was gone. I couldn't restore my bookmarks because the only one available was from today and it`s "clean." Is there any way to restore my account data? Because everything was there: settings, bookmarks, passwords, history.

do know computers very well, have used firefox for all my web browsing, firefox kept crashing according to screen so it opened saved apparent older version and I lost all my bookmarks and passwords, please help

Yesterday, possibly related to updating to version 148, my profile completely disappaered. My old profiles are not visible under about:profiles, but are present on disk. They can not be imported with firefox -P. How do I get my profile data back?

Dear Firefox Support Team,

My Mozilla Account was Accidentally Deleted Today and I'm Looking to Recover my Data (History / Passwords / etc.). Is There any Way to Do so?

Thanks in Advance

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.

I run the current Firefox version under Windows 11 Pro on a Dell Inspiron 15 3530 laptop, Lately, I've been having problems with my bookmarks:

• First, I found that I had somehow lost a large number of bookmark tags; it took me several days to restore them,
• Next, I found that I had lost a bunch of bookmark subfolders; the bookmarks (for the most part) are still listed under their tags.
• When I try searching for tags in Bookmarks Manager, the search yield no results
• When I try to restore my bookmarks from a previous date, I get an "unable to process file" message.
• When I try to open the profile folder through the debugging information page, I get a "file not found" message. After some searching, I found the profile folder not at "C:\Users\croge\AppData\Roaming\Mozilla\Firefox\Profiles\7csymh5k.default-release", but at "C:\Users\croge\AppData\Local\Packages\Mozilla.Firefox_n80bbvh6b1yt2\LocalCache\Roaming\Mozilla\Firefox\Profiles", Something seems to have gone haywire--did I miss something, or is there an error somewhere?
