Firefox Community Forum

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?

We had a power cut yesterday during wild weather. When I restarted my iMac and opened Firefox I found that all my bookmarks had disappeared. I've done some investigating online for fix it steps but nothing is appropriate. Firefox is only listing one Profile for me.

No one at the law firm where I work remembers the password for the law firm I work for. When I download it I cannot get the icons I had before. Somehow I now have Microsoft Bing which I do not want. My icons are there. Any suggestions how to do this?

I have spent the last two hours trying to get my Bookmarks amd history back. I am exhausted and very worried. Firsty I tried going through the Menu, but there is no list of backups there. and there is no history, either!

Then I tried looking in about:profiles - I only have three:

oi853qa9.default, 7sh8b0ii.default-release, and d41afk6n.default-release-1. Only the first one of these contains any bookmark files.

Ideally, I would like to restore the most recent of these, or the second most recent, if the newest one is corrupted in some way. However I cannot find a way to do that from the information I have seen tonight. I hope you will be able to help me out,

Yours Sincerely, Ms Jacq Felis.

THis morning, the motherboard on my laptop crashed SO I went to WalMart and bought a new one I downloaded Firefox..........and the bookmarks are 9 years old. And the bookmarks is where I keep 100s of passwords. I have to have them!

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.

I recently downloaded and installed the update to Firefox browser. After installation I find that all my bookmarks (and I mean ALL) are gone. They are gone completely. First time that has happened with an update. Very frustrating!! I had a lot of bookmarks. Lots of music and specific web sites that I frequently use. Now they are gone. Totally disappeared What happened? Is there any chance for recovery. The installation instructions say that I will not lose any data, etc., etc. And I believed it.

I have been trying for days to get back my passwords and bookmarks. The support articles are not terribly helpful. All I want is to restore my bookmarks and passwords that Mozilla wiped out. I have the old Firefox folder but the support page says just copy what you need. please, is there a simple way to restore my bookmarks and passwords without having to jump through hoops.

not all windows appear in the drop down "window" menu, and a different number when each window is on top. Weird.

Using Mac OSX. Nothing is "full screen." Seems to be nothing to do with if a window is minimized or not.

I have restarted. Recently updated, and lost profile, but recovered it, but lost all my open windows & tabs, so now I have only 5 windows open. Seems to be nothing to do with if a window is minimized (OSX) or not. Needs a better mechanism to save open windows & tabs along with profile data.
