The closest I've seen to "perfection" in regards to tab addons yet.

This + some custom CSS enabled me to *very* closely match Edge's vertical tabs, and while there's a lot I could criticize about Edge, its vertical tabs are superb and really in a league of their own.

Thanks for bringing these over to Firefox, much appreciated!

Seems faster than other sidebar tab extensions (I'm a tab hoarder with thousands of tabs opened all the time ._.), thank you.

Excellent add-on. But unfortunately the add-on does not work properly since Firefox version 107 and is now unusable.

Update: This is a mistake on my part. The extension works. I just forgot that I use a custom userChrome.css which doesn't work anymore with Firefox 107...I have to update it.

我之前是用Tree Style Tab。但是有个问题他的一样网站喜欢收起来很不方便，而且不知道去那里找取折叠收起来一样网站的选项取消掉！
然后我看见该软件就试试了下很不错，我个人挑不出什么毛病我就用过两个类似软件，所以才给五星

Of all the vertical tabs extensions I've tried, this + Firefox vertical tabs .CSS is as close to Edge vertical tabs in terms of quality as it gets.

You can hide the title bar by following these instructions: github.com/ranmaru22/firefox-vertical-tabs

F the other two side tabs this one takes the cake.

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

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
