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!

Smoother than Tree Syle Tab, but lacks many of it's additional plugins that expand it's functionality, also i'm surprised i found no option to restore Tree order when i restore parent Tab, i TST restored parent tab get placed above it's children like nothing has happened, in Sidebery i need to reorder them again. Is that a bug?

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.

TST user here.
Maan, please, first of all, why is the f Sideberry don't have same colors as of my theme installed? Secondly, I didn't find any way to show tabs as icons, to customize it via CSS, and etc. Sorry, but TST is better!

Sidebar must be too wide to see container colour marks
