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 ?

Absolutely furious. My bookmarks have completely disappeared and none of your suggested 'articles' is any help at all. I certainly won't be using Mozilla any more if you can't tell me how to rectify this.

There are times that when I open firefox that some of my tabs that does this weird thing where my tabs from the previous session that I left doesn't load up, from what I see is a blank tab that doesn't access the sites I left. It's been twice since I encountered this and I can't replicate the issue. When it happens I try checking out the recently closed tabs or window it doesn't show the ones that didn't show up.

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?

Hi, Today 8-7-25 Mozilla automatically upgraded to version 141.0.3. Now all of my bookmarks are gone. I can't find them on my pc. There are two profiles listed in the profile section. Neither seem to have my bookmarks. I have a lot of bookmarks and some are very needed. Please help me recover all of my bookmarks. Thank you, Geo

I don't know whether this happened after an update - there was one a few days ago, but I only realised this morning, after switching on the computer, that all my bookmarks are missing. The toolbar is there, empty, only reading "For quick access, place your bookmarks here on the bookmarks toolbar"... I wish! I tried to restore the bookmarks - but it seems there is no backup to restore at all. Then I tried to check my profiles, but there is only the one currently in use. Then I tried to move a tab to the bookmarks toolbar - and nothing happened. Then I began to panic: toolbar apart, we're speaking about years of bookmarks, most of them related to my research for my books... All the advice in the support seems to point towards profiles and backups, but, as I said, it's clearly not my case... Please, please, please: help!

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.?

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?

My PC died and I could not boot from bootable flash drive.

I had been backing up the system with Acronis to a WD Passport.

I purchased a new computer, and when I did a restore, upon starting Firefox, I did not have my old bookmarks, which are many.

Aren't they stored in a backup? If so, how do I get them back. I'm sure that some of the bookmarks came over from Netscape Navigator.

Thanks,

Bob

I lost all my personal data on Firefox as soon as I changed the password and I did not know that you can lose everything that I had registered in the download box and the previous archive. Now I am very, very mentally disturbed and I do not feel safe and I am very sad about what happened to me. I am crying now. What should I do? My psyche is really broken due to the lack of information....

Hi

I've just booted my machine and opened Firefox, only to be presented with a completely fresh install.

All my settings, bookmarks and history gone. It was fine yesterday when I closed it and powered down.

I'm running Kubuntu, I've checked the .mozilla folder and nothing...it's like my profile has just been overwritten.

Not happy at all, I'm starting to dislike Firefox.

Can anyone offer any help or advice please?

Thanks in advance.

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?

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

100% of my bookmarks have disappeared. I tried backing up to older version a month ago and still no bookmarks were found. I had over 2000 bookmarks. any suggestions?? Marty
