Amazing features, but glitchy. Especially when I have two windows open using it. Tabs get sorted weird, especially on restarts, sometimes phantom tabs (that aren't selectable but show up in the menu) linger, tab order gets screwed up, etc.

I find this a much better interface than the tab bar. It's not quite as nice as the old version of the addon but I think this is about as good as can be done with the new WebExtension model.

I love this Add-On... use it and abuse it...
It does take a bit of practice and learning, but it sure works for me...
Only thing I hate is... I can not get rid of the Tab Bar at the top of the browser...I see no point in having it there....
Is there a way to turn it off?

Love this app and have one feature request.

I normally use the default tabs at the top of the window, and open Tree Style Tab when I have too many tabs open. It would be cool if there were an option to automatically open the Tree Style Tab sidebar when a specified number of tabs were open.

So an option like:

Automatically open sidebar when n tabs are opened.

I just cannot understand why FF is the only browser which has such handy plugin!

Tree Style Tab occasionally seems to hang when restarting Firefox,or following a reboot,in which case I simply close the sidebar (using X),then reinstall it with Firefox still running,reopen it,and everything's back to normal again.

No longer working after updating to 2.6.8. I now have the well fabled 'white dot' syndrome,and uninstalling and going back to the previous version doesn't fix it unfortunately.

В Tab Tree было авто скрытие панели владок, переключение по клику между двумя вкладками. Этого всего очень не хватает.

awesome!

This is a love-hate relationship. The concept is great. The implementation is horrible.
Sometimes this add-on just mixes up the hierarchy of my tabs and I painfully have to reorder them by hand. This can be a lot of a work since this add-on espeacially makes sense when you use many tabs.

Absolutely essential. I've used this extension for more than 5 years and refuse to ever browse without it. The best of all the vertical tab applications and really should be the STANDARD way to browse now that we all have wide screen monitors. Nothing else makes sense.

This add-on is one of the main reasons I use Firefox over any other browser.

This is great if you have opened like 10 more tabs.
But I love to auto show/hide if it more than xxx tabs open.
Is this possible?

I thought that the giant grey bar it makes is intrusive, also I dont like it zooming out the page at at. A transparency setting would be great. Ways to make it smaller and less intrusive to the website would be nice as well.
