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.

после обновления,при вкл браузера, Sidebery открывается на вкладках. Как сделать как раньше, чтоб открывались списком закладки, а не вкладки не нашел. И еще-как сделать текст еще компактнее?

Very nice add-on ! is it possible to add the possibility to show the pinned add-ons ? it would be super useful for my RSS reader

Fantastic add-on. Thank you for finally updating to 5.0! The old version was incredibly slow with a large number of tabs (approximately 5000+ tabs -__-) but I didn't want to go through the hassle of installing the 5.0 beta. Now that 5.0 is official, this add-on handles my ridiculous number of tabs effortlessly. Thanks!!

Awesome update, I love it even more now! Keep up with the good work!

Very cool 5.0 update, do you accept Monero (XMR) donations?

This extension is probably the main reason I use Firefox. Almost every behavior can be changed and adapted to my needs. Thank you to everyone that made it possible, you make me happy.
