I really like what this add-on does. The problem is that it never stops doing it. I have tabs that need to be in a tree structure. That part is great. But I don't want new trees created every time I run a Google search or open a new tab from an existing page. Sadly, there seems to be no way to control that. So if I want to use this add-on at all, I have to manually flatten every newly created tree. It is a chore, and it seems unnecessary.

Just found this, love it! :D

Pretty simple, works great, excellent for organisation and power users with MANY tabs :D

długo używam ten styl i dobrze się sprawuje
I've been using this style for a long time and it works well

I cannot imagine using a browser without it. It's a pity that Firefox breaks compatibility and right now my main issue is that I cannot share tabs between devices.

Extremely nice

1) wish the "header" in the tree pane could be much more minimal.
2) wish there was a GUI control or d&d operation to create new tab-group elements vs bookmarking `about:treestyletab-group?title=New Tab Group`

Overall great, but it becomes too laggy when many tabs are opened.

I can't imagine using a browser effectively without this. The non-existence of such addon for Chrome is also the main reason I am not using Chrome.
This performs well, has all features I need, is stable... what more can one want from a plugin.

The only downside is it can't hide the default tab bar, but the author explained that it's because Firefox does not allow that.

Great extension for managing a bunch of tabs!

One annoyance: Sometimes when I click on a tab, if I'm moving the mouse a little it'll put the tab in a new window. Can be a little annoying to move it back if it has a bunch of branches.

Otherwise, great stuff!
