Review Edited: Awesome Addon, A worthy replacement of tree style tabs or Tab Group Manger etc etc. This one is full blown package with a lot of customization.

One request from developer to add tab search feature.

удобная штука спасибо.

awesome! simple, does everything i need and even more! Thank you!

top tier addon

When Sea Containers did not work even after the fix for the addon fiasco, I was distraught. I have 150 tabs open and firefox would be hard to manage without it. I had the good fortune to find this excellent addon. It is even better than Sea Containers!

The best sidebar container & tabs add-on which I came across. Three points which could be even better: (1) Show the number of tabs inside a container next to the container icon. (2) Make it an option to have the containers also displayed in a folded view merged inside the area where the tabs are listed (like the two other container sidebar add-ons do). (3) Add support of moving multiple tabs to a different container in one action.

Damn.. I was looking for some tree tabs with tab grouping.. This.. it looks perfect.. Unless i end up with some annoying bugs or performance issues I'm sticking with it :D Great Job :D

If there's one or two things I'd love to see..
edit: actually option to switch Multi Account Containers displayed icons to STG would be perfect.

Great start. Big future

Very nice addon, well designed, and adds real value to the tabbing process.

I keep lots of tabs open -- all day -- personal, work, client etc, and this addon is the first I've come across that makes containers actually useful!

This extension is amazeballs. It kicks the pants out of the other vertical tab offerings!

Well done. Thanks for creating it.

Interesting, but is the 'Access your data for all websites' permission truly required?
