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?

I accidentally refreshed Firefox when I was having problems and didn't realize Refresh meant wiping everything clean. I found another thread about this, but it's 8 years old and things have changed. How do I use the "Old Firefox" folder on my desktop to restore all my bookmarks, history, etc.?

When I opened Firefox, all my profile settings were back to a Default. Lost all my settings. Looked up solution on Google, couldn't find an "Old Firefox Data Folder" anywhere.

Tried the other listed "profiles" in my profiles folder, none were my most recent profile with all my settings from the past months.

How can I find the profile that was used before my update which was done 7/27/25 ish.

Since yesterday, I suddenly had to recreate my Firefox account, which I have used for a long time. For no apparent reason, my email was not recognized as an existing account when I tried to synchronize my browser. As a result, I created a new account using the same email address. Consequently, all my email masks have disappeared from relay.firefox.com. Is there any way to recover those masks?

Firefuxxed was refusing to open new tabs so I shut it down and restarted it (always fixes it) and all my pinned and open tabs were gone with no way to recover them, it took me half an hour to manually restore the pinned ones one by one but not all of them as I cannot remember all of them let alone all the open tabs I had (hours of research gone down the toilet).

There should be a way to backup and restore pinned and open tabs so this doesn't happen, the history option does nothing.

OS: Linux Mint 22 fresh install from a week ago Previous version of Firefuxxed updated after this shamossel.

I just transferred my data from an old computer with Windows 10 and now have Windows 11 on my new computer with a new version of firefox as my browser. How do I restore my bookmarks?

I asked a question about a week ago. I can't even see the question anymore. While this was going on I received these emails. All times are in Australian CST.

I am as much a believer in security as the next person but I don't understand what is going on,

I have had no response to my original ticket, which I beleive was number 305857 which I can no longer find any refernce to in my account, and I still have a completely blank Library! and I can't even make any new bookmarks!

Plaes help, Yours sincerely, Ms Jacq Felis (AKA Kaelkitty).

I find recovering deleted bookmarks difficult in Firefox. Typically, I am told: "on August 12 you deleted 12,540 bookmarks. Do you want to recover them all and over-write your existing bookmarks?" To which the answer is obviously, no.

What I want is a system much more similar to the Microsoft File Explorer Recycle Bin, which lists deleted files on an individual basis, so if I have deleted a file, I can see its name, the date it was deleted, and where it came from, and I can restore that particular file. Or, since we are talking bookmarks here, recover a particular bookmark.

How can I achieve that? Is it possible?

My wife's Firefox was triggered from an e-mail link and in the process got updated to release 141.0 The result is that the tabs from the previous verion have not loaded. Can I still recover them?

Firefox on my mac has been acting buggy lately. The last time I quit and reopened it, all of my windows and tabs were gone. there is no restore previous session available and the recently closed tabs and windows options are grayed out. How can I restore?

I got a new PC and tried to sign in to my FireFox account to synchronize. But, foolishly, I ended up resetting my password! Don't know why did that, as I was able to locate my password stored elsewhere. I think this action erased all my data in my online profile & I cannot access my account data (bookmarks, user IDs & passwords) online.

Since my data was still in my old PC, I followed the directions for finding my Profile folder. I copied the folder contents to the Profile folder in the new PC. This has not worked.

I realize I wasn't supposed to copy the entire folder contents, which could be the reason why it's not working. Also, the profile folder contained a large amount of data (3 G). So, it's possible that not all files have been transferred correctly.

Please help me!

Thank you very much! Madoka

Where are my bookmarks? Everything is gone with the update, and you didn't warn this could happen. Is there a way to recover the bookmark file? Profiles does not help for there is no new profile there. I NEED THE BOOKMARKS FOR WORK!!!

Since updating Firefox on June 30, 2025 on my Dell desktop computer that runs Windows 10, most of my bookmarks are no longer visible. Only four of my bookmark folders are visible and most of their contents have disappeared.

However, 1) my uncategorized bookmarks - those in "other bookmarks" are still visible, and 2) If I go to "Manage bookmarks" and do a search, I can find all of my bookmarks including those that are no longer visible.

In addition, I can no longer add or delete bookmarks. It looks like I can do add a bookmark and it will let me go through the steps of adding a book mark - it even says I can put it in all my old folders that are otherwise no longer visible. But one I complete the process the bookmark does not show up.

I have read multiple Firefox Help articles about disappearing bookmarks and have taken all the steps suggested including: - Attempted to restore backups of bookmarks - didn't work. It shows me the multiple old backups but when I try to restore one I get the message "Unable to process the backup file". I have tried it with at least four of the old backup files - all without success. - cleared cache - did troubleshooting mode - refreshed Firefox - uninstalled and reinstalled Firefox - looked to see if I had a different profile other than my default profile that I could switch to. I do not see another profile.

Nothing has helped. Any suggestions would be greatly appreciated.

Thanks

Something or somebody emptied my bookmarks. I tried the import/restore routine but was told that Firefox "was unable to process the backup file." I also tried System Restore without success. Can you help me? I don't want to leave Firefox, but the problem reoccurs, which is maddening and time-wasting. Thanks, Bruce Berckman

version 141.0.3 on a 2019 iMac 11.7.10 ... when this version was downloaded, bookmarks and history disappeared. Is there a way to recover or do I have to begin from scratch ?
