Works extra well with the tweaks from https://github.com/ranmaru22/firefox-vertical-tabs

J'avais écrit un avis expliquant que je regrettais l'impossibilité de masquer les onglets horizontaux. J'ai tenté de suivre à la lettre le lien framagit donné, malheureusement, il n'y a rien à faire, le script ne fonctionne pas. Je suis passé sur un autre navigateur, beaucoup plus personnalisable, et les onglets peuvent être mis là où l'on souhaite.

De todas las que he probado, me resulta la mejor con diferencia. No falla, y es muy fácilmente personalizable. Además tiene algunas características únicas que la hacen aún más útil.

i love it here its amazing being creative in life thanks..... here's the best

如果能像edge一样集成到浏览器层面好了，现在这样既没法收起也没法让顶栏只显示当前标签页信息。。。

awsome!

Simple, lightweight (87 kb), and useful for quickly navigating around my tabs when I have 20+ tabs open.

I was one of the QA's that tested the original add-on, and I was very sad when Mozilla decided to ditch it from Test Pilot. So when I've found out about yours I got really, really glad. I could not go back to the horizontal tabs anymore.

Thanks for maintaining this add-on, and for quickly fixing everything that it is reported. I really appreciate it!

Hello your last update 2.3.0 actually broke the whole extension on my end, it doesn't adapt to any dark theme anymore and dynamic doesn't work, actually it seems that whatever i choose in the options it doesn't change anything. I was just browsing and it suddenly went white themed with unresponsive settings.
EDIT : I just tried reverting to version 2.2.0 and it works fine so it's definitely the update.

A nice, simple tab sidebar. However, I prefer Tree Style Tab or Sidebery which have more functionality.

It's really good except for one problem - sometimes, dunno why, greyed tabs (unloaded) suddenly turn normal despite when you click on them they need to actually reload. It's annoying because it waste ram. A solution could be marking multiple tabs to unload them.

Edit: I use uBlock origin
