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!

I don't know what you're doing but EVERYTIME I do an update lately, something goes wrong. Today after update, my STGs are affected and ALL ARE GONE. I do NOT believe this is their fault. And you put this dang auto Startpage when launching window, I did NOT ask for that. I am so pissed, how do I get them all back? I had things I was working on that were very important. What else did you add to FF that I don't know about? I don't want your updates anymore. You screwed me big time. And I don't want the extensions YOU think I should have: Google, eBay, Bing, etc. wasting my space. I'm not the only one either, seen lots of complaints.

HOW DO I GET THOSE TABS BACK??????

Firefox crashed and I cannot recover my tabs from history. I click on restore all tabs and it does nothing. The tabs I was hoping to recover do not even appear in my history either.

I was asked to create a new profile in order to keep using Firefox, despite never having an account. After I clicked okay, it opened the new version of Firefox, but without all the passwords, bookmarks and history of the past few years. This is really inconvenient. I have since then made an account, but the fact that I can't find any of this data anywhere has me worried that every time I update Firefox it will wipe my account.

I keep a lot of tabs open (~60) in any particular session - I find it's faster in this way to get back to a site.

About every six months or so, I lose *all* these tabs because of Firefox's inadequate session backup system. It only saves two or three total backups, some of which are completely out of date. But the worst scenario is when (1) some site pops up a new window; (2) I mistakenly close my main window before the new window; (3) I open this new saved window once or twice by accident, causing my 60-tab session backup to be overwritten.

Using a third-party session manager (I have tried all the well-known ones) can mitigate this problem, but doesn't really solve it because the re-opened sessions aren't quite in the same format as Firefox sessions and so lose information. In particular, I often lose each tab's icon as well as metadata for Tree Style Tab.

Could Mozilla please consider a more robust session backup system for Firefox? All it would take (I think) is to allow the user to choose the total number of backup sessions and the frequency at which a new session is added. Thank you!

I recently installed Firefox for security reasons, but I now realize it might be not better than other browsers... I had a (good) number of tabs opened in 12 Simple Tab Groups, which were opening all right everytime I restarted my computer. But today, Firefox opened and oh, all my tabs have disappeared ! All 12 Simple Tab Groups are empty. In the Recently Closed Tabs in History, I only could find and reopen 26 tabs - a very small part of the tabs I had... Please, tell me if there is a solution to recover all my tabs. Is the problem with Firefox or with the Simple Tab extension?

Hi

Lets say i have 100 tabs open in my session. I mistakenly open a new window with one tab. After closing this window and starting firefox again, it starts with this one tab, so i have lost all my previously opened tabs. Is there a way to get those back?

Thank you very much. Dimitris

Hi I need help as my Firefox browser got uninstalled this morning I had to reinstall and all my saved data has disappeared,

Please help retrieve old mozilla firefox data.

hi, Recently, I updated my Fire fox browser after updating my all the bookmarks and saved info on browser are vanished. now browser also not support login with google id's why? , I switched to firefox just because I never face this issue with firefox. Now it does same as the other's.

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

firefox updated to 128 esr all of a sudden (i didn't click update or download for this) and when i went to open firefox, the appearance and everything changed. it looked like google chrome and none of my bookmarks and settings and layouts were there. they just DISAPPEARED. i tried googling how to to fix this and for some reason every time i search it takes me to another search engine instead of google. (this is beside the main point though). I'm so frustrated right now since all my bookmarks are gone (literally having a breakdown). I tried looking through the help articles and all of them just say to use the backup profiles or that there are bookmarkbackup files in my profile folders or that firefox would download a folder with files from the old version but none of that happened. I looked into my folders for older profiles trying to find places.sqlite files but NOTHING. there is literally NO backups or profiles dated to before July 16 2025; the day it updated (shown in screenshot) and there is NO bookmarkbackup files anywhere. i have signed in to firefox prior and had my devices synced for awhile and no issues so there should have been previous profiles and data saved onto my computer. Please help, I really need my bookmarks back!

hi firefox, today i get an update of firefox, after updating my browser my all the saved bookmarks, history and my login details are wiped out. kindly check this why is it happened and resolve this thing. the data saved in browser is important for me, help me to recover it

I'm an older pensioner, I've no wish to learn more tech stuff which is unconnected with my question. For years I've been concerned at the invasive nature of Microsoft products and so want to get rid of Win10/11 and install another OS. (I have hundreds of documents in Wordpad (.rtf) and MS are just cancelling it!) It'll probably be Linux based. So, simply I want to take my existing Firefox browser with passwords etc., to my new OS. I asked this question in Firefox and it seems Mozilla can't get over the fact that I don't want change my iOS browser to a synched up Firefox. I don't want my phone connected to my pc. Perhaps that is difficult for today's tech whizz-kids to understand but I can't help that. I'm not really technical but have had Firefox for nearly 30 years, so can anyone tell me if it's possible to copy my Firefox into a folder somewhere perhaps, and reconstitute it to work with my new OS? It certainly used to be possible. Thanks.

Hi,

I don't come from an IT/Tech background so this has become a hassle for me. I have a "Old Firefox Data" file on the my desktop and that seems to have sub-folders with my bookmarks, sessions, logins, etc. How do I retrieve those to the new Firefox browser.

Thanks!
