Great extension
Help me in tracking my mess while surfing around.

Just to make it clear, this plugin is the reason I came back to firefox ! THANK YOU for creating & updating it .

Wow, this should become a default for FF browser, I could never ever work without it. Helps my productivity and reading/working style a lot. I can only recommend it.

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.

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!

awesome!

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.

I use LOTS of tabs. Having grouped tabs, with a tree structure (like a filesystem) is the most sane way to manage having lots of tabs open. I cannot understand why this isn't default behavior. This is the first extension I install immediately after installing Firefox. Every. Single. Time.

This is the single most useful add-in for Firefox, and is actually the major reason that I still use Firefox as my primary browser. The ability to organize tabs into groups so that I can manage tasks, and easily switch between groups related to the various tasks and projects that I am working on makes my life so much easier. If you have more than a few dozen tabs this becomes the _only_ way to effectively manage them. It's so useful that it's used by pretty much every developer in our organization.
