This extension changed my live, literally! My Tab related problems are all gone and I'm saving lots of RAM, which speeds up my PC!

I've used plenty of tab manager extensions, nothing offers me the ease of use and productivity boost that this one does!
Particularly love being able to clump tabs together into different windows and name them, as well as color code them, for easy identification and switching.
For someone who regularly has 300 tabs open and gets frustrated easily, this extension is a lifesaver :)

Efficient, useful and tiny footprint!

Exceedingly useful, particularly when used with other tab managers like Simple Tab Groups.

A regex engine would be nice in future updates too. I'd like to be able to close, say, www.youtube.com, but not www.youtube.com/Username

EDIT 11-15-25: Add-on seems to be distintegrating in later versions of Zen (Firefox). Sometimes it closes way more tabs beyond the criteria I give it, sometimes zero tabs show up in it at all. Still a great add-on when it works.

all very good; but like anything, it is btter once you are more familar with using it

By far the only feature packed tab manager that has what you would expect a tab manager to have and not be annoying about it. Being able to switch the view style of the tabs being managed in the popup or its own tab is a really nice addition that makes it far more user friendly than the many alternatives I have used. It also was extremely self explanatory to use, there was no need to dive into Github issues just to figure out how to use the thing. Most importantly, it includes the experimental feature to save sessions that so far is working well and means that I can eliminate other extensions than just other tab managers with this one, which I like as having too many extensions makes me a bit nervous in terms of long term sustainability of my workflow.

My only gripe with this extension is cosmetic, I would like to be able to control the background and foreground colors in dark mode as the default is not my favorite. That's not worth a star though.

Absolutely stellar. I can see the tabs and manipulate them at will. Just need to explain to some users the existence certain tips and tricks like ctrl+left click or dragging between lists and it'll be just what I'd want.

Tab Manager is a brilliant piece of software/add-on, I use it continually for finding pages, searching for information and just leave useful tabs open and use it as an excellent search on my history.

I really push the software, at the moment over 2300 pages/tabs open in firefox, one window! Doing a search on all open tabs usually find the page I looking for and if wanted can open a group of tabs in another window and know all the pages open are probably useful, it's like an intelligent favourites from the browser history. Many thanks Markus and best wishes from the UK and other software developers.
