Crashes about 60% of the time when I try to use the "Close tree" function - I have to to go "Manage Extension" and select "Options", then it comes up with an error that says "A web page is slowing down your browser" and I select "Stop It" to get it working again. Consistently.

Also it'd be really nice to just have the option to have it close tree automatically, but I'll settle for just having the function work without crashing the extension and freezing my browser.

Why can't i open a saved session in private browsing mode?

Fantastico, semplice da usare ma con features molto interessanti (ad esempio vari modi di raggruppare i tabs, possibilità di salvare singoli raggruppamenti nei Bookmarks, o di esportare tutto su file)

problem open/close

MUch better and complete than Tree Style Tab. I the idea of make tab groups , and search tabs with certain URL. Excellente Add-On

This is a truly priceless extension for anyone who uses many tabs and wants to organize them in an exceptionally useful way. Brilliant!

You can see more tabs than in TST and it works well with groups too.

Bravo!

It would be great add only if it will be more stable ... Very often groups are missing or tabs are not in their groups after (re)start of browser :-( Sometimes helps to switch panel into another view and then again to Tree Tabs, but many times I lost the tree structure definitely. Several times all tabs were lost (after firefox update) and addon started a crashed again and again.

Very professionally looking, easy to configure and with tons of options (for those who like to tinker with it more).

Tabs organized as trees, but what's even more interesting, also as folders (for holding nested tabs) and as groups (for holding groups of tabs and folders)!

It's themable, and its theme editor is as thorough as it is easy to use.

Quite a bundle of awesomeness, don't you think?

It's the one I wanted! Group tabs in folder

Best Tree Tabs extension ! And I've tried several !
This one groups the most features I need :
- Tree view
- Tabbed Groups (it would be nice to be able to select background colour of tab like in Opera)
- Pined tabs at top
- Themes (you can create your own one quite easily)

And more !
I also use this one with Opera ;)

Thanks for this great "must have" extension !

Looks nice, with several features. It might even have what I'm looking for, which is to save and update multiple windows tab sessions, but after more than one hour with it, I still don't know even if it has that (others were really intuitive without any learning curve whatsoever). And there is no instructions. Looking for another one, 4 stars because it is difficult to find an add on with the tree structure though, and I'd like the developer to continue working on it...

Sometimes the tree structure of sorted tabs gets lost, which is really annoyning. The backup feature does often recover this, though. I've tried a couple of similar add-ons, but I'm always coming back to Tree Tabs because of its many useful features. Hoping for a new, more stable version.
