This is one of those things that, once you have it, you wonder how you ever lived without it.

The simple ability to use tab groups and collapse when needed is an excellent feature. A must have!

Also (responding to another review), I am using macOS Monterey (Intel processor), and I do not experience memory leak issues. FWIW.

Awesome extension, I like how it uses the same theme as the one preset for Firefox

firefox should has this feature built in

Thank you so much for this last update. This is such an improvement !!

this is probably one of the best extensions I've used, with features that are useful, obvious & intuitive right out of the box.
I have a few extensions that I install on every browser, and this will be one of them

多段タブがバージョンアップのたびに使えなくなるので見限り代替となるものを探していました。
