I use tab groups actively and would save much of my work in my ever-growing list of tab groups. I saw today that many of them had disappeared. I wasn't signed into Firefox and nor do I have any different profiles made. I see two tab groups that I made yesterday but none from before that. How could this happen? How do I recover so much of the work I had saved up?

dear sir/ mam:

like in safari, i had pinned the websites (as tabs) i visit regularly.

when i restarted the browser, all tabs were gone.

i have been using this feature in safari since a decade and no pinned tabs have been lost.

please guide.

All of a sudden Firefox stopped reloading my previous tabs when I start Firefox (whether or not it is set to open automatically on start up). I have ensured the relevant boxes are ticked and I have even reinstalled Firefox altogether - and all to no avail.

I am using Firefox on a W11 64 bit desktop. I have used it for years and have never had this problem before.

This was working just fine up until 2 days ago. As the title says, when I close firefox, it is now no longer restoring my tabs from my previous session. Closing via the x does not give me the option to restore my previous session.

I have:

Tried unchecking the box, closing firefox, opening it again and rechecking the box. No success.

Uninstalled firefox, restarted my computer, and reinstalled firefox. Still no success.

I am open to further suggestions.

Hello,

I just found out about the Firefox group tabs feature and love the concept! However, on my computer (Linux, Pop OS), the default theme makes it difficult to see the underlining color for the group. Is there a way to increase the thickness? I've added a picture of how it looks, there is only a very thin (in this pic, blue) line underneath the tabs. I can barely see it, making it's use harder...

I really can't add to my Summary other than it's a fairly recent issue, started in May 2026, possible April. About.config is set to False. I hope some has a solution - it happens when I'm dealing with live incidents.

I have read a Mozilla blog that you can make tab groups now, i have tried to make a tab group and it for some reason i can't, i looked at Mozilla's guide for the Tab groups, they didn't help. Does anybody know how to fix this problem?

Please consider optimizing the resource management while minimizing a tab group. This would be an amazing option to be included. If its already present in the tab groups inherent workflow, please add more documentation about its effects and more. Maybe adding optional workflows for a scenario of usage like a energy efficient usage button for a tab group is a great idea.

the tab groups feature doesn't work. WHen i drag one tab onto another, nothing happens, other than the tabs go back and forth. Can't put one tab over another and no group is created.

I've got Reading the full Article on GROUP TABS that has been released yesterday on My Firefox it Got Update and Installed But I just couldn't found the "Add to the Group option when I click right at any of my tab" + If I drag over one on Another Tab it just got replaced like they substitute their Places No BOX Border line Shows No Group Created NOTHING. I'm a Nearly 6 Year Old Firefox User I NEEDED that FEATURE SO BADLY PLEASE FIX it SOMEHOW. ThAnks Regards: Loyal USer

The new group tab feature of latest update of Firefox browser (just downloaded) doesn't actually work. What's detailed in the description doesn't exist. I'm using macOS Sonoma version 14.7.5 Of course it restarted following the upgrade.

I am using the Firefox browser version 138. However I am not able to use the Tab Groups from firefox. I cannot add any Tabs to any group as there is no option for that.
