I'm personally a heavy tab user but have always wondered why there is almost no support for tab grouping or customization in the native tab bar in Firefox.

I think making it able to group like Google Chrome does for example or at least giving more access for extensions and add-ons would significantly improve the UI in that regard.

On Chrome there is Tab Grouping, and it's like putting some of your tabs together in a closable folder on your tab bar or whatever it's called. You can group together your tabs, move them around together, and give custom names and colors to the groups. I do like how if I have many tabs I can scroll through the tool bar but I want this too.

@Anonymous  I would mainly make a use of the function when tabs are grouped as I don't have much of a need to rename tabs individually but I couldn't see why that wouldn't also be able to introduced with the tab grouping but it may also be too much to code it all in in one thing.

Maybe that could be left open for extensions where the grouping function will be natively supported.

When you have several tabs open, it would be nice to be able to divide them into groups, 
for example Work, Home, Hobby, so it will be easy to keep track of over 20+ tabs,
just like an archive folder where you can add new documents so you can you have 20+ tabs in one tab

@Vinci480thank you for feedback ;D

Sounds like a great idea. I miss tab groups, it used to be part of Firefox at one time.

@AnonymousAnytime 🙂

IE8 had a neat feature that coloured similar (same domain?) tabs the same colour. You could easily identify similar tabs based on their colours. I like the idea of grouping or identifying tabs of the same domain/type:

This feature is really needed. Containers just aren't useful for everyone and there isn't an extension I've found that does it well.

Hi all,

Back with an exciting update...

This idea has been reviewed by our product team and we want to explore it further. This means that we plan to continue researching and collecting data to help determine the best way to move forward with improving tab management.

Please continue the conversation here (the more details to support your case, the better) and stay tuned for updates.

I do not understand why you delay the implementation.
The functionality, the screenshots are clear
I don't like "tree style tab" extensions
I am now forced to use in parallel another browser that already uses this horizontal tab grouping. Some people are also concerned about security.
FIrefox must also facilitate the use of many simultaneous tabs!
Thank you for integrating it. I was hoping for a big hit with version 100!

I would definitely love to have exactly at least these features:
Naming Tab Groups
Picking a Colour for Tab Groups (If a preset from 10 colours or being able to take colours yourself doesn't matter really)
Unloading Tab groups (this could maybe be left for an extension though)
and Closing and restoring whole Tab Groups


I think those features would be the most important and most common ones that would throw the useability to the front with the likes of other Browsers.

Excellent to hear the Product Team is looking at the idea more closely, I have had to switch from FF to other browsers at work because of the missing Group Tabs, I work with RMM and Ticketing software and without Group Tabs it is like driving a Volkswagen Beetle down the Daytona 500 race track, FF cannot compete with my workflow without Group Tabs. I am not a FAN of Edge or Chrome but the Group Tabs feature is a must to keep my multiple tabs organized and process work quicker. Please also look into putting the unused TABS to sleep after 5 minutes, this is a huge bonus in Edge and really helps with less consumption of the systems memory stack. 👍

I agree with @Vinci480 above, that's pretty much what I would like as well.

With the difference of having "Unloading Tab Groups" as a native feature, it not being left for an extension.

Also, a better UI/UX implementation that Google Chrome has would be appreciated! (Maybe only a color strip on the bottom instead of around the tab? or color the whole tab?

Let your product designers play around with different Implementations.

There are addons that do a good grouping of tabs. But for me, especially when the top bar is full of tabs when I am researching something I would like to see maybe as "subgroups" the chrome like implementation. And of course why not this not to get synchronized with a tree view sidebar ? There are extensions who do something similar but we need a native framework for all these addons to play well together !

Making moves

I don't like tab groups in chrome, because even when groups are closed they use space on the tab bar (the colored "dots").

If I have many groups then I have too wasted space in the tab bar: I have 22 tab groups, so 22 dots is too much space used for no reason.

Instead I'm currently using the simple tab groups extension, and it works perfectly: no space wasted on tab bar. It has a simple icon and I can position it where I want: currently I put it on the left of the url bar, separated from the other extensions icons.

Also why mozilla should use its limited resources for this when there are many better extensions available?
