This helps browsing a lot, but it does have a few bugs. Right now, I'm experiencing a bug where the tabs have been slightly truncated, chopping off the favicons.

Very outstanding addon, but since 2 months it's super slow. When disabled Firefox is working fine. But enabled it slows so much down that Firefox is nearly unuseable.

This add-on has changed the way I browse the Internet! It makes managing multiple tabs so easy!

so much better having tabs down the side than in a row that changes size and then has to scroll sideways. If only FF would let us remove them.
TreeStyle Tab also lets me have nested tabs so it keeps threads together as I search and browse links.

without the "reload all tabs" made it very unusefull, such a stupid update

Merveilleuse et si pratique extension. Un énorme merci à vous !!!

You need to urgently remove/move/add possibility to remove the "Close tab options" menu in the context menu. Now it can be accidentally triggered to close all tabs when actually trying to reopen closed tab! Just lost over 50 tabs doing so!

Otherwise the add-on is great and recommended for anyone with high number of tabs open.
