Hi there,

I have just updated to version 139, and I still do not have access to tab groups on one of my devices. I have the devices synced and fully updated. I have tried restarting firefox many times, I have gone into the config and set browser.tabs.groups.enabled (already true), browser.tabs.groups.smart.enabled to true, and browser.tabs.groups.optin to true. still nothing and only on this computer. see attached images as proof of software version and config settings. Someone please help! I have been dying without groups after moving from chrome a year or so ago, so when I found out they were added I was so excited.

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 lost all my tabs groups with the the update to release date for Firefox 138.0.4 on the 2025-05-19. Tab groups are still configured but my sessionstore.js is missing. I notice that there is a backup in Session-store backups dated the 2025-05-19 so I presume the tabs groups are still stored there. Can anybody suggest how to get the tab functionality back? I'm hesitant to just restore the sessionstore.js -- the actual tab group functionality is gone. I can't even recreate the groups.

Just wondering, are the Tab Groups only saved locally or also on the Account? Have also heard that the Tab Groups feature has sometimes been disabled by itself, when re-opening Firefox, and they lost all their groups and had to enable the feature again. But I don't know anything else about that, and just would like to know, if the Tab Groups can be or are saved on the Mozilla Account.

I absolutely love the new tab groups on Firefox. I am a lawyer and i keep a TON of tabs open at the same time. I might be working on a case, and I can create all the tabs related to that case together, come back to it a day or more later.

I also open up a zillion news articles every day. Some are fun (Fun Articles Group), some are about our declining society (Rule of Law Group), some are about AI (AI Articles To Save), some are Case Law I save for my internal library (Case Law to Save Group).

The problem I am having is that each of the Windows where these various tabs are kept is are not seen by the Tab Names. So, if I go to my pinned Taskbar icons across the bottom of my screen, and toggle across the Firefox icon, the many different labels that pop up are ONLY the tab names.

That is, there is nothing reflecting the Group name to which the tab belongs. I just spent all this time grouping my tabs together in separate windows, and when I want to go quickly to one of those Windows (each Window has a Separate Group Name in my personal system), I cannot tell which one is which.

So, my recommendation is that Mozilla designate in the taskbar prompted tab items which Group each tab belongs to (if it is assigned to a Group). It would make toggling between the tabs sooooooo much easier and efficient.

Additionally, I love that when I assign a new item/tab to a Group, it automatically groups them with the other members/tabs in the Group. However, after a certain point, it gets ridiculous. Perhaps there can be an option where you can separate the Groups into two or more Windows (eg Group named Case Law to Save, if I have 10 different ones open, put the 11th one in a new Window, instead of just adding another tab to the ever-burgeoning Window full of tabs).

Maybe I am the only idiot who has so many tabs open that these issues are a problem. But the mere fact that Mozilla created the organizational tool of Groups suggests to me that I am not the only one who keeps a lot of tabs open at the same time.

I have no idea how to suggest this improvement to them. I am not a coder. I cannot contribute in this way.

Thanks to those who contribute to the improvement of this product! Michelle

The new native tab group feature has an option to "Save and close group", implying that you can restore the group. But doing this, you will find that the group disappears.

Is this a known bug? Has anyone figured out how to restore a saved tab group?

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

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.

The latest firefox update introduced tab groups, something I've been eagerly waiting for ever since chrome released it!

However, my firefox's tab groups don't hide the tabs correctly. In the video demo I see that when you click on the name of the tab group, it should collapse all the tabs and hide them.

In my firefox, when I click the tab group name, the tabs don't get hidden as expected.

Here is a video that shows the bug I'm referencing: https://imgur.com/a/8ewW1a2

I tried disabling all my extensions and restarting firefox, also tried in private mode, and it still was having the same experience.

Are there any about:config settings that I might have accidentally changed that could be causing this?

Thanks!

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?

How will I know when Tab Groups is available to me. When it is available will it be an extension or built into a version DISREGARD THIS QUESTION I HAVE THE ANSWER

Hi,

In my Firefox Developer install the new tab groups feature seems to now be working like one would expect, but my main Firefox install (Firefox desktop 138.0 (64-bit)) has some issues.

I can add tab groups, add tabs to groups, but left mouse clicking the colored tab header does NOT close the tab group, like it does in Developer browser. Mode of tab group clearly changes, as the tab is either dark or light colored after a mouse click.

I don't remember changing any other settings lately in about:config, except setting tabs.groups feature to true, and I don't have too many extensions installed, and I also tried disabling all the extensions, but that didn't help.

Greetings...

I am a frequent user of multiple tabs whenever I use Firefox. As a result, the new Tab Groups feature interests me, primarily if it will help my to organize and manage my multiple open tabs. Initially, I have the following specific questions.

Q: Is there a maximum quantity of tabs that a Tab Group can contain?

Q: Is there a maximum quantity of Tab Groups that can be open at the same time?

Q: Does the use of one or more Tab Group negatively affect the performance of my web browser?

Q: Can a Tab Group be bookmarked? (Periodically, I need to bookmark a group of open tabs and I am currently able to do so by selecting all of the tabs then bookmarking them as a set.)

Q: Does the new Tab Groups feature represent a way to reduce the number of open tabs that appear at the top of my web browser - basically, a way for multiple open tabs to occupy a smaller space versus scrolling them across the top of my web browser?

Thank you very much for your feedback! Take care...

Are tab groups like containers i.e. isolated from the others, so thay I can access sites logged into different accounts for instance or separate browsing experience/cookies ?
