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?
