I enjoy the grouping functionality, but it has some significant performance issues. Whenever a group/folder is opened, it seems to automatically switch to whichever tab was last active in it. Even if you click away or do something else before it finishes, it will drag you kicking and screaming to that one tab. Sometimes, it will be very slow in this regard, only switching to said tab well after I've already left the group and collapsed the folder, and this can also happen with two groups at once, helplessly dragging me back and forth between two tabs. I don't know if this is an intended feature, but please add an option for disabling it.

My only issue Is with how big the group tabs are, if they were maybe half the size, or had a customizable size that would be amazing.

The only extension I've found that comes close to duplicating Chrome's tab group feature.

Does exactly what it says and helps reduce tab clutter!

Thank you for being the only add-on I could find that replicates Chrome's tab grouping!

Would love the option for the tabs in each group to be highlighted constantly (ideally as the group icon colour).

I am required to use Edge for my work device & while not being able to use Firefox's extensions is frustrating, one advantage Edge does have over Firefox is tab grouping. I do like Edge's method of grouping tabs in 'folders' that appear by name in the tab bar. Firefox has no such functionality, which is a shame. This extension is the best stand-in for that functionality, and while it is not as refined as what I am used to, I assume that is more a restriction of Firefox rather than the developer's abilities. Overall, very good.

As everybody else is saying in the coments, glad to find this extension, as it was a deal breaker to me using mozilla at this point. Thanks Nameless Guy.

I use Chrome at my work and I got used to tab grouping and helping me stay low on the laptop resources while keeping productivity.
I prefer firefox in my own computer cause privacy reasons, but to me is the one of the big browsers which is behind in user experience. With this add-on, things leverage a little for me.

Hoping this extension keeps improving and either mozilla implements it natively or give this developer the tools to replicate or even improve Chrome Tab Grouping feature.

not as good as in chromium based browsers, but still usable (without suffering even)
God bless you!

Works mostly perfectly as far as I'm concerned, and those missing things are the fault of firefox, not the (active) developer. Good plugin!

This is exactly what I wanted, which was something similar to chrome tab groups where it keeps tabs within a single window and I can see the name of the tab group next to the other tabs. It lets you color code them now too, and it required a lot fewer permissions than other add-ons.

Exactly the kind of hold over I was looking for while I await the great Chrome Purge of 2024.

Tried almost a dozen different add-ons, working down from popularity, and this was the first that does a good job of approximating Chrome groupings (in the tab bar, collapsing, colour-coded, etc).

Should I maybe learn to not sit on hundreds of tabs I organize into work flow projects and hobbies to only not look at the grouping for literal years? Possibly. Should I re-learn to bookmark and use website specific save-profiles like it's 2006? NEVER!

Thanks Dev bud!

I've been looking for a plugin like this for a while now. Chrome-esque groupings without having to use chromium browsers.

Does a great job of replicating the Chrome tab grouping. Thanks!

As close as it gets to chromium-style tab groups. Much simpler to use than the other chromium-style tab groupers in the addons store.
One feature that I would love to see would be an option to always keep the grouped tabs highlighted in a color, and when collapsed, keep the tab grouper highlighted in that same color (and make the color customizable, similar to chromium).

Great Chrome-like Tab Grouping for FireFox!

[Updated review]*
There are a number of glitches with this that can still be worked out, but some of them can sort of be considered features in a way. Not too sure how much support for this Firefox has, but core issues that previously existed (a key one being that closing a window with a tab group that was not the last window opened disabled the function of tab groups that were opened, meaning tabs needed to be reassigned into a group to function again -- this is no longer the case as they groups function when windows are re-opened using History)

Groups Tabs do not have the ability to collapse the group they belong to still, so the workaround is to have a tab outside of the group to click on to collapse the groups more easily

Moving multiple tabs into a Group Tab will move each tab individually - which can be a slow process. If you are mass moving tabs into a Group, please make sure you do not change the Group Tab name in the middle of the process of the tabs being moved, or you may end up "losing" some tabs (they exist, they're just not accessible until you fiddle around a bit such as disable the Extension due to them being hidden under a group that exists but isn't visible on your tabs list)

Moving multiple tabs within a group to change their position can also glitch up a bit. Normally, if you move tabs individually, they will be confined to the bounds of the Group. If you move them as a group, this can potentially glitch up and allow tabs to be positioned outside of the bounds of the Group (eg. very front of the entire set of tabs in the window and in front of all sorts of other tabs that are in front of the Group Tab -- instead of being at the very front of the set of tabs contained within the Group and immediately behind the Group Tab). I consider this almost a feature. Issue is... this messes up the order of tab positions, so your new tabs may end up popping up in unexpected places and not immediately behind the tab you are opening said new tab from

Overall, fairly usable with a few glitches here and there. If you've tried this extension before and had issues with it (eg. the whole issue of Group Tabs not functioning after reopening a closed window during a session), it may be worth checking out once more to see if the issues you've had were resolved

This is where it's at, if you need tab groups for Firefox. The other extensions are too odd and obtuse for me, and this replicates Chrome-like grouping.
