Works really well and exactly as described. Very helpful usage guide in description. Thank you TheNamelessGuy❤️

i really like it
it was the closest to the one on chrome and unlike the other ones its not trying to take all my data...
will still be using this over firefox's new built in grouping system
custom icons win 😍

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.

A good approximation of Chromium style tab grouping. There are issues, but I assume that's based on the way Firefox itself is built and limitations in circumventing those designs. It essentially does what is says on the tin, but it's moderately to extremely janky. Hopefully it will get smoothed out in the future.

One of the more impactful/frustrating issues I've run into (and the work around) is:

After closing a browsing session and reopening Firefox, one of the windows' tab groups no longer displayed, however tabs continued to hide/show themselves according to the invisible group's functionality. Unfortunately these were a group of tabs I intended to work through.

In order to access any of these hidden tabs, expand the tab menu (the inverted carat to the right of add-tab button). Go to hidden Tabs and select one. Since the Tab Group's logic still functions, this opens the selected tab and all others that were in it's group. However, the group doesn't appear so leaving the group will cause the issue to persist.

Shift+Click to select the tabs in the malfunctioning group. The Right click and add them to a new group. This new group will be visible and functional.

Kind of a pain that this is necessary, but it beats not having tab groups at all

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).
