I updated Firefox this morning to 139.0.4 on my Mac and now the '+' sign to add a new tab no longer appears on the tab bar. I can still add new tabs with Command T however.

Any suggestions on how to restore the '+' sign?

Thanks Dan

I have a strange problem and cannot find any reason for it.

On two different machines (with the same Firefox account, same extensions) I'm using tab groups, also in multiple windows (restoring them after launching Firefox).

In one installation I can close all tab groups without any problem.

In the other if it's the last open group, trying to close it (by clicking its header) opens a new, empty tab instead.

I'm pretty sure the settings of both installations differ but I cannot find any setting that would cause this behavior. It's especially annoying because with many open tabs I have to scroll through all to find the group I want to open instead, open it, scroll back to the other group header and close it.

Any pointers on where to start looking?

Hello. I love the feature. I didn't know it was a new feature because I started using Firefox around April. I saved my group tabs, very happy about it. Then I close and save it, then I opened it again, it was great!

I am a student, I use my group tab to add the tabs that have the resources that I need to, and would also like to study for more knowledge and for my next school year.

There was no problem at that whole time. In April 21, there was no problem until April 22, 23 no problem. But I forgot my charger at that time, because I was at my mothers house. Then I wait for weeks for my charger to come back, about 2 weeks for my laptop to revive there in my grandparent's house.

When I got my charger, and opened firefox. Wait, but at first when I opened firefox, it showed me that there is a new update, an update about tab groups that I already now. I looked at my group tabs, and they are not there anymore.

What should I do to get them back.

I was excited to receive the new Tab Groups feature and am now disappointed that it's not working and I've 'lost' dozens of tabs.

Here's what I did: I created several groups by right-clicking and added tabs to each of the groups. Since it appears that only way to collapse a group is to "save and close group," I closed each group. Now they are all gone. When I right-click to create a new group or "add tab to group," the closed groups are nowhere to be found. Plus, I do not see a "list all tabs icon" on my toolbar to reopen the grouped tabs, which is what [article] says should happen.

Suggestions for making this work?

I seem to have accidentally set up tab-groups, on desktop. Probably I fat-fingered a shortcut to group some tabs. This is a function I'll never intentionally use — since I'd rather not cut off my fat fingers, is there a way to permanently shut off tab-groups?

Thank you kindly.

I have the most recent update and have been excited about tab groups, but it's still not working on mine. I thought the update would be available to all as of May 6, 2025. Is this happening to anyone else?

Hello,

I dislike the Group Tabs feature. So many times I've accidentally created a Group Tab and then had to figure out how to un-group them.

I've tried to change the value of the "browser.tabs.groups.enabled" preference to false, but it doesn't stick; after restarting, the value is always back to "true".

What’s up with this?

Thanks, Andre’a

According to the most recent update page, this function should be working for all users by now. (see attached screenshot).

It is still not working for me. Has the timeline been postponed? Is anyone else still unable to use this function?

Thank you!

the tab groups page i was shown by firefox says i should be able to group my tabs starting at the latest yesterday but my tabs still just move out of the way and refuse to group. i found container groups but they work nothing like the page showed. i have firefox version 138 and the tab groups was starting to be roled out on 137

I'm running v138.0.1, but the ability to group tabs that was supposedly introduced in v137 is completely absent from my browser. I can neither drag tabs onto another to create a group, nor create groups by right clicking on a tab. What's up with that?

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

Hello, so I have been waiting for the Tab Groups feature and saw it should be available by the 6th of May, but after waiting, still no Tab Groups, I am not sure what to do or if there is a problem.

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.

I recently updated to Firefox 138.0.1 to use the new tab groups feature, which allows grouping and labeling tabs, as outlined in Mozilla’s support article (expected for all users by May 6, 2025). However, after updating, I don’t see the tab groups option when dragging tabs or right-clicking them. Has anyone else faced this issue? Could it be due to the progressive rollout, a conflicting extension, or a setting I need to enable? I’ve tried restarting Firefox and checking the tab bar, but no luck. Any community solutions or workarounds to enable tab groups would be greatly appreciated! Please share your experiences or fixes.

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

Due to not everything reloading every time, a connectivity problem I can't blame Firefox for, I now have 3 windows, together comprising all the tabs I want [OK some are duplicated, but it's easy to remove those...]. How can I stick those all back into one window? - with my pinned tabs at the head., which is where they were before...

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.
