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!

up til yesterday I was completely satisfied, my pinned tabs were icons only, which is what I wanted..I could see all my vertical tabs.

now, for some strange reason, its not showing me my pinned tabs as icons but rather normal compact tabs, and actively interfering with my workflow on firefox.

hi, great extension, sadly the css style editor has to much bugs, code that don't save properly, after a restart, so many times the code you add disappear and if you didn't saved in a external file makes all lost, I hope you are trying to improve it. thanks.

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

normally, when I drag and drop a file towards the firefox panel, that file opens in a new tab. is it possible to provide this in your side panel extension?

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

You still have tabs at the top stealing space, you can remove on Edge browser.
EDIT: Hiding tabs done with wiki, thanks. The only problem is three top right window buttons stopped working.

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