Well made and more usefull than you might think before :)

great addon !
keep going ;)

its good

Hands down the best browser extension I've ever seen, and the constant development & helping resolve issues is outstanding.
Thank you for all your work.

In my opinion, this is one of the most important Firefox extensions.
For years, I have been using it daily, along with several of its associated extensions.
In the course of the extension's evolution, bugs have arisen but they are a sign of Piro's (its author) constant effort to improve it and he has promptly solved them.
@Piro, thank you very much for your work and your generosity.

I love this add-on! The organization!! "chef's kiss"! If you are looking for some input requests or ideas, I would ask that you make the child, sibling, and parent options more accessible, like from right click or some other button as apposed to the hidden button next to the plus sign at the bottom. Thank you for creating this add-on! It has done wonders for me in my need for organization.

Indispensable part of using Firefox. The developer is very active and understanding. Great job!

After last update some css styles doesn't work anymore, forcing scrollbar is the worst and no solution that i find works for me. Can "no scroll bar" be implemented in addon itself?
