it's sooooo simple but good

This is not first time that after closing and opening the browser, all tabs are lost. Very unstable add-on. Not suitable for work.

Ce n'est pas dans ma langue

Must have extension! So many options.

I have tried several similar Add-Ons, so I can assure you're grabbing the right stuff here.

The Add-Ons offers you a very good amount of thoroughly well-thought-of settings and features, highly customizable. I love that, there's no software with too much options for me.
Don't panic, you don't have to do anything before using this Add-On because it's - out of the box - GOOD
(and beautiful too)

I'm actually writing this review because I waive using it for a while to test out Mozillas first take of vertikal tabs. I find it way too simple. Like overly-simple, rather even unfinished. I'm so glad I can go back to Sidebery again so that I don't mind formulating a beautiful review for you in the middle of the night.

Peace

This extension just re-defined what a browser should look like
