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.

Hi, I'm Albert.

I had like 10,000 open tabs (not exaggerating) and these tabs are gone after a blue screen error and a few Windows updates. I want to restore those tabs, but I can not because the "Restore the previous session" option is grayed out.

Are there ways to restore these open tabs?

If there isn't one, then I want to restore all the websites I have visited over the past few years and manually filter them.

How do I do it?

The Firefox library contains history but the oldest history it contains is 2024 December one. I guess the dedicated folder removed my old browsing history as it was filled up?

What I read is that places.sqlite file contains all the browsing history. Is this right? My places.sqlite file size is 80.0 MB (83,886,080 bytes). Is there a size limit on this file? I wonder if this file contains all my browsing history.

I have my places.sqlite file and DB Browser installed on my computer. But I don't know what to do next after opening places.sqlite file.

If there are better suited applications for my purpose than DB Browser, please recommend me one with a little instruction.

Long story short, how do I restore my open tabs or browsing history?

Please help me.

Hello, I'm experiencing an issue with tab groups in Firefox.

• I use multiple tab groups in my browser.
• Normally, if I close the browser (without manually saving the groups), Firefox restores everything exactly as it was when I reopen it including all my tab groups and their current tabs.
• However, if Firefox crashes while the groups are open, I run into a problem:

 * When I restart Firefox after the crash and try to open my tab groups, all the recent tabs are missing.
 * Instead of restoring the most recent state of the tab groups, Firefox loads an old, manually saved version from the past.
 * Any recent changes to the tab groups are completely lost.

This has happened multiple times now.

• • System Info:**

• Firefox version: 141.0 (64-bit)
• OS: Windows 11

I'd appreciate any help or suggestions to prevent this data loss after crashes. Is there a way to make Firefox auto save tab group states more frequently, or restore the most recent session even after a crash?

Subject: Help recovering old Firefox Sync data using my Recovery Key

Hello Mozilla Support,

I’m trying to recover my old Firefox Sync data, especially my bookmarks and saved passwords.

I still have an Account Recovery Key that I saved on August 27, 2025. However, after signing in to my Mozilla account today, my account page shows “Account recovery key: Not set”, and syncing does not restore my old bookmarks or passwords.

I may have reset or changed my Mozilla account password today without using the old Recovery Key during the process.

Could you please confirm:

Is there any way to use my old Recovery Key now to recover the previously encrypted Firefox Sync data? Is the old Sync data still retained on Mozilla’s servers in any recoverable form? Is there any other recovery procedure available for bookmarks, passwords, or previous Sync data?

I still have access to the same Mozilla account and the original Recovery Key file. I will not send the Recovery Key itself unless there is an official secure procedure that requires it.

Zniknęły mi zakładki (nie ma ich ani na pasku, ani jak wejdę w zakładki- w ustawieniach i w zarządzaniu zakładkami). Hasła te co były zapisane mam dostępne na moim koncie.

When I tried to log in to my account earlier today, I found that it was gone. I used my recovery key to create a new password and now lost all data, passwords etc. What do I do now? Why did this happen? I am not very computer literate but have tried all of the suggestions in your help forum and nothing works. Nothing has changed on my computer since my last login yesterday. Firefox is my home page and browser.

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?

Three days ago a window popped up asking me to update Firefox. I did and afterwards my personal bookmarks listing disappeared. I tried rebooting everything. No luck. I went to your website and followed all of your suggestions, but again nothing worked; mainly because I could not find on my computer the info the last step in your suggestions were asking for. (I did get a message several times telling me I was using an old Firefox profile. I tried to investigate, but each time your instructions told me to look for something as the last or next-to-last step, I ended not being able to find it on my computer. Again, I have tried everything. Please help me.

Hello, I just purchased a new desktop computer. I have passwords and bookmarks that I would like to move over to the new computer. Can this be done or do I have to manually move each item. It would be so much easier to recapture all. Thanks for you help.
