È la cosa più simile ad Arc Browser vista finora, veramente ottima.

When I open it, I want it to default on 'bookmarks' not 'sidebery'. I'm not going to spent all night with my head buried in Settings trying to figure how to change the default.

Started OK, went well for a couple of days, then just disappeared! Re-installed, no show. Forget it, not worth the hassle!

low performance

This extension is incredibly useful. It stands out as one of the best I've ever used, and I've been online since the early days of the Internet. Excellent work, Max Badryzlov! Thank you so much, buddy!

Great!

mate, this add-on is more than an add-on. this should be integraded into firefox. it is much more superior in managing tabs than anything mozilla has made (e.g. firefoxs new vertical sidebar looks in comparison so halfhearted).
i just found out that i can customize the tab menu too (often to unload tabs).
i am really impressed with this masterpiece! thank you very much

Testei várias e essa, pra mim, foi a melhor. Intuitiva, organizada e com bastante opção de customização.

Best Tab Manager so far

This add-on is simply excellent!

I started using it for tabs organization (vertical, tree, groups) but found so many more related features that I did not know I needed!

I hope you can continue working and supporting this extension for...ever :)
