Hello everyone,
My name is Devin Sandoz and I’m a product marketing manager at Mozilla. @ssmagula is the product manager. I'm posting on behalf of the Tab Groups team who are working to help you be more productive and happy when using Firefox. We want to thank you for all your helpful feedback in Mozilla Connect and invite you to help us improve Tab Groups before a wider release.
What are Tab Groups?
Tab Groups will help you organize your tabs. Whether you keep your tab bar tidy with just a few tabs or you hoard thousands of tabs, Tab Groups will make it easier than ever to switch between and re-find tabs and tasks—all while maintaining the privacy of Firefox. Say you’re planning a vacation over spring break. A group will help you to keep all your flight searches, lodging options, local restaurants in one easy to re-find place.

Creating groups
Once fully released, there will be a helpful call-out explaining how to create groups. To create a group drag a tab on top of another tab and pause until you see a highlighted drop area, then release it. Or right-click any tab and select Add tab to group. Next you can name it. For example, you might want to create a group called News. Add news sites by dragging them into any expanded group. When you’re done catching up on the news, select “Save and close group” so you can remove it from your tab bar and re-open the group the next day. All your groups—open and closed—are always available via the “list all tabs menu” (a downward-facing caret at the right of the tab bar)—even if you close a window or restart, no account needed.
Known issues
Our team is working hard to make Firefox Tab Groups the best they can be, and we thank you for your help and patience as we discover and smooth out any rough edges.
Faster, better, easier
At Firefox Tab Groups are just part of a larger effort to improve browser productivity. Our designers and developers are creating new tools to improve productivity and efficiency including a sidebar with vertical tabs, better profiles. Our goal is to help you achieve more with less effort so that you can focus on your spring break vacation, and not on your tabs or the browser.
We can't wait for you to try Tab Groups so you can tell us what you think!

I would love to see a feature that automatically groups tabs from the same site into tab groups. For instance, if I open two YouTube tabs, they would be automatically grouped together. Additionally, I would like to see a stacking feature, where these grouped tabs not only appear together but also stack on top of each other. When I hover over the stack, it would display a list of the tabs within it, allowing me to easily select which one to switch to. This would free up a ton of space in tabs.
I don't think any other browser has a feature like this and I think it would be pretty useful.

I would also love to see these features! Long time ago I used Vivaldi Browser for a little while and ever since, I wish tab stacks were available in other browsers.

I just downloaded Vivaldi to see what you meant, and yeah, this is exactly what I was talking about. I had no idea that someone had already done something like this.
So if anyone was wondering, in vivaldi you can stack tabs like so The 3 on the end being the amount of stabs in stack.
When you hover over that stack, you'll get a drop down menu to select tabs from with in that stack to jump to.

Great, thank you, we've been waiting for this for a long time, it's a really convenient and necessary feature.
Now, the most missing feature is the ability to move collapsed group labels.
The ability to group tabs by simply moving the tab to the label of the collapsed groups.
And like in edge, when you hover over a group label, the preview should show tabs without expanding the group label, and show the number of tabs.
Also, an additional feature to automatically group tabs without user intervention, for example, by domain, similar to chrome extensions.
Grouping of tabs for the mobile version of Firefox.
The ability to choose a custom color for group labels.
Is any of this already in development or in the pipeline?

Tab groups and vertical tabs are useless for me without workspaces.
03-05-2025 10:51 PM
I don't like that when I on one of the grouped tab sand collaps the group, then 1) browser switches my current tab and 2) I can't navigate inside the closed tab using Ctrl+Tab

I hope that:

All your groups—open and closed—are always available via the “list all tabs menu” (a downward-facing caret at the right of the tab bar)
This bit of UI isn't available if the new vertical tabs mode is enabled, which makes it annoying to get the tabs back.
03-06-2025 05:47 AM
Are workspaces coming to Firefox as well?
03-06-2025 07:09 AM
Yes finally! I'm liking it so far. But I do have a request: to be able to share groups.
03-06-2025 09:12 AM - edited 03-06-2025 11:18 AM
Please add two things to make this perfect:
1. The option to keep one tab visible when the group is minimized.
2. The option to collapse and expand the group by double-clicking the active tab of the group.
Pretty please with sugar on top. Even if just as a config flag. Please. Nobody has to know. It will be our little secret.
Okay, sorry for being weird. I really, really want these two features. Please make it happen.

I've just switched to using vertical tabs with tab groups in v136 with the requisite config options enabled. Seems like a pretty good setup so far. One thing I want already, though, is a button to add a new tab to a group. I know you can do it with a right-click, but it'd be cool to have it doable with one action. Alternatively or in addition, being able to Cmd-T a new tab in the current group would be nice. Maybe it could be a config option or a slightly different T-based key combo. If this functionality happens to already exist, let me know!
03-06-2025 01:04 PM
Thank you for working on tab groups! I don't have that many requirements for such a feature. Only one thing is essential for me: I use a lot of tabs and my way of working involves moving tabs around a lot. And that's exactly what I want to do with tab groups as well. I need certain structures to work with and at the same time I need the flexibility to be able to adapt these structures at any time. Unfortunately, moving groups is not (yet?) possible. As soon as this is possible, I will definitely use tab groups. Unfortunately, without this option, I can't use it yet.

What will the migration story be for users of existing tab group extensions? Eg I use Panorma Tab Groups.

I'm mostly focusing on the vertical tabs feature + tab groups. It's a bit weird trying to create tab group with the mouse. I'm wondering if yall could change it to be more like Sidebery's implementation. I have vids to show the weird behavior vs how it's done in Sidebery.
