I-Firefox Community Forum

Hello,

I'm writing because I’ve encountered an issue with the tab groups feature in Firefox.

Some time ago, after a browser update, I noticed a new feature that allowed me to group tabs thematically — I could name each group (e.g., "Study", "Work"), choose a color for it, and save and close groups to reopen them later. I found it very useful and used it a lot.

Last night, I decided to declutter my browser and closed several tab groups using the built-in menu. A bit later, I shut down my computer, but perhaps too quickly. This morning, when I turned my computer back on, Firefox was very slow to start. After a restart, everything seemed to work fine again, and the open tabs were restored.

However, all my previously saved (but temporarily closed) tab groups disappeared. In the tab group menu, I can now only see the ones currently open. I’ve searched through all the settings and history but cannot find any way to restore the missing groups.

Is there any way to recover the tab groups that I had previously saved and closed?

Thank you very much in advance!

When I do this:

Click the menu button Fx89menuButton to open the menu panel. Click Bookmarks and then click the Manage bookmarks bar at the bottom. In the Library window, click the Import and Backup button and then select Restore.

I get a blank slate. No files listed.

When I go into the Profile, I see C:\Users\whatt\AppData\Roaming\Mozilla\Firefox\Profiles\shgdgxn6.default-release-1752271533405\bookmarkbackups

How do I restore bookmarks from that file?

I upgraded to Firefox 143.0.4 and lost all of my Bookmarks. How do I find and reload my Default Profile? Also, I cannot load anything in Firefox I am forced to use Edge which I do not like at all!!!!

After an update on F***fox meant I could not access my emails or radio programmes, etc, etc, I reverted F***fox and refused to update it daily. Now it has updated itself and I have lost all my bookmarks, hundreds of them. WTH have you criminals done?

Firefox just updated and ALL of my bookmarks are gone. There is NOTHING. WTF? I am not a computer person so reading help articles just makes my head spin and of course I can't reach a real live person at Mozillabold text. Can anyone help?

CCleaner wiped out my bookmarks and their functionality. I have repaired, then uninstalled CCleaner. I have refreshed, uninstalled then reinstalled Firefox. I have logged in and out of Firefox. I have made an HTML file of bookmarks from another device in order to try to import them. Firefox bookmarks will not proceed to an upload stage. I went into setting to add the HTML of bookmarks and it said "this is not a bookmarks file." Well, Firefox made that HTML bookmarks file so I have no idea how that could be. Nothing I have tried has worked.

After the update occurred my desktop bookmarks was not here anymore! I need to get that desktop bookmars back and I can not figure out how to get it back PLEASE help me!!

Since Firefox automatically updated (14.0.1) on my MacBook Air (2025 model) several weeks ago, the Bookmarks and History functions haven't worked. Can anyone suggest how I can fix this?

a few days ago I received a message that i had an upgrade from Firefox. After that I can't find the bookmarks I had saved for paying bills as well as other important items.

My SSD boot drive crashed -- Rebuilt system (brand new SSD boot drive) and reloaded all of my data from a separate backup, however Firefox profile is gone. I have copies of the old profiles including the places files, etc. Following Mozilla's instructions I reloaded the old profiles. Firefox starts right up but *without* my bookmarks, etc. Unfortunately there was no "old Firefox data" folder saved and I could not retrieve the bookmark specific backup. Thoughts? Thanks!

I was able to use it this morning from my macbook. But the afternoon I was on sites where my passwords usually fill but now everything is empty, everything had been deleted. I tried to log out and back in to mozilla and sync, but everything is gone. Over 100 sites and passwords. How this happened ? Where can i ask for help since Mozilla doesn't offer any.
