This extension is very convenient

That's the kind of things that once you use it well, you cannot imagine going back.

I wanted to use it to have Chrome convenient experience with tab groups (Chrome is better in that, but don't support multiple search engines and other cool functions), but I can use it only on desktop where I don't need tab group really much because I already have list of all tabs when browsing current tab, and can't on Android where I really needed it. Also realization of tab pinning and tab containers is not very convenient. And creating new tab button is (only) on bottom side of page which is not convenient too. Also I always forget about tabs tree and start using native top menu, and tab tree doesn't even (only icon like in chrome mobile groups maybe) copy there.
P.S. Also with 100+ tabs Firefox crashes several time a day, but I'm not sure that's just because tab tree

I am a coder who is working on a big web project, to organize all my tabs, this extension plays a very big role. I recommend this extension to everyone.

I think this is a great learning experience

I've been using this for so long. Since I heard it announced on Security Now podcast probably over 10 years ago. I can't imagine a world without it. I can't use any other browsers since they don't have it.

Well made and more usefull than you might think before :)

great addon !
keep going ;)

its good

I tried the latest version because it looks like a useful extension. I discovered that it would completely reverse the order of the tabs I open with Morning Coffee Quantum, even if I disable all Tree Style Tab's control settings over new tab placement. Eventually I removed the current version and installed v3.9.22 as was suggested by some reviews on this site. It now works correctly, so I will stay with this older version.
