This is the best add-on on firefox. Everyone's lives would be better if they used tree-style tabs. I am a tree-style tab evangelist and the add-on is the primary reason that I use firefox.

Tab power at your finger-tips

Tree Style Tab is the main reason Firefox has been my default browser for the last several years. It is hard to believe that Firefox--nor any other browser from Chrome to Edge to Opera contains native support for these style of tabs. For any user that like to have more than 20 tabs open at a time, I find this to be essential. Absolutely the best browser feature, I just wish I could figure out a way to make a monetary donation to the developer!

Great addon! Without Tab Groups it is a lifesaver when working with lots of tabs.

All the issues have been fixed! Flat out, this extension is the main reason why I use Firefox, I can't stand Tabs on top; they are a mess when there are more then 3 open tabs! No other browser handles tabs on the side well. Chrome's similar extensions are all horrible. Edge and Vivaldi don't handle "tab children" the same way and you can't tell what tab a new tab is from if you do "Open in new Tab".

And then add in all the other addon Extensions that Piro has made for TST, it can't be beat.

I utterly fail to see why this sort of thing isn't just an option for ALL browsers. I guess it just shows how technical of user I and others that need something like TST are.

Best of the best. I was looking for something similar, very pleased with the result. We just have to wait to hide the tabs at the top ((
upd'2024: ... and search in opened tabs by caption please ))

This works pretty well. They way the hierarchies work is great. My only complaint is that the hierarchy structure gets lost when I close and reopen the browser. I have found a session manager that handles this so I wish it could just be added into Tree Style Tab.

Tree Style Tabs is definitely the best way to handle having a lot of tabs open at the same time.

My favorite and most used Firefox plugin. Increases my daily productivity and ease of mind significantly. Also the main reason why I stayed with Firefox for years (even though Chrome was and is very tempting). The overhaul update of this plugin which now supports Firefox full screen mode on Mac OS and got rid of all other bugs I noticed before is stunning! Love it!

很喜欢这个扩展。

This is a fantastic extension, but recent versions randomly launch a pop-up tab with usage instructions that is impossible to close without restarting your browser. The software should not force itself in front of the user like that.

It's come to be an essential extension for me. With the death of tab groups it's the next-best-thing. I only wish that there was a better way of creating group folders (dummy tabs).

Edit 2020-04-30: Still loving it
