This add on to firefox works great. It gets my bookmarks where they're easy to access

Beautifull UI, easy to use, powerfull...

Really excellent, the way this product should be done!

this is PUSHKA

I like it a lot better than Tree Style Tabs. Sidebery is the superior add-on.

It's under very active development and receives regular updates.

It's a real must-have in Firefox, and I think Mozilla should implement it as an official functionality.
