Been looking for an extension to keep my pinned tabs open after I close Firefox. This seems to be doing the trick :).

Has a ton more options that I have yet to dive into :D.

It is the reason I switched to Firefox. Had to write some CSS, though.

Added five minutes ago and it's already blown my mind. I feel like I'm rediscovering Firefox. Excellent!

Excellent! Great addon, more useful than TreeStyleTab: It has all what you need out-of-the-box. Many preferences with logical structure. Great thanks for Snapshots - It safe me few times and I didn't waste a lot of time for recovering. I especially like a feature to save the whole tree of tabs as bookmark: add with fool folder structure or just as group of standalone tabs. It's beautiful and handsome, no doubts ♥

good. It really is one of the best Firefox addons.

But to mention one downside, the Tab "Unload" is inconvenient.

It would be nice if the Unload function could support mouse and keyboard.
