5.0.0 works flawlessly. ∞/5 all day long.

5.1.1 requires you to turn animations on. neat. 5/5.

Takes some tinkering and getting used to, but helped my quitting my addiction to Arc Browser. Should inform users that you must take snapshots if you want to keep your tabs

Thanks for performance improvements with a lot of tabs in 5.0

i come from treestyletab, and this extension is amazing

I haven't been able to live without vertical tabs in years. This is the best Firefox implementation of it I have found yet.

Just got a big update that improves a bunch of stuff that was already good.

I just discovered that clicking on the tab you're already on switches to the previous one you visited, so repeatedly clicking the same tab switches between the two every click. I have no idea what I'm going to use this feature for, but it feels well designed and I love it.

This extension has helped increase my productivity so much! If you have tried side-bar/tree view extensions and been disappointed, try this one, its so good you will never go back!

The latest release from about a week ago included so many UI and quality of life improvements I felt compelled to write this review. Before, Sidebery was a functional and necessary utility that allowed a ton of customization options, including CSS. Now, it's a joy to use! I discarded all my custom CSS and have been loving the default UX.

This is literally the best browser extension I've ever used, in any browser.

Since the UI rework, it's been an absolute pleasure to use Sidebery! It was great before, but it has become so comfy and beautiful. I strongly recommend to anyone who wants to organize and manage their tabs easily.
