This has to be one of the most consistent extensions with Firefox. The interface is very transparent. Does not suffer from the issues I often had with TreeStyleTabs.

Love this app! Once I figured out how to use it, it really has transformed by million tabs situation to help my productivity! Thanks!

fantastic addon for anyone who needs to work on more than one thing at a time

The option "Discard tabs after hide" will close them or just unload them from RAM?

Complete game-changer for productivity use. This extension has drastically changed the way I use my tabs, allowing me to easily partition and keep context in every type of activity I'm working on. I was initially annoyed by the zip backups in downloads, but now that I've set up my tab groups, I'm glad there's a reliable external (and automatic) backup.

Just one word: Awesome!

I've been using this add-on for about a year now, and while it's hit some typical development roadbumps, it is a fundamental part of my browsing experience. It is simply a fantastic tool for organizing the hundreds of tabs I have at any given time, and backing them up as bookmarks is a fantastic bonus feature. I think there's a reason this add-on has been designated as "recommended" by Mozilla/Firefox - I wouldn't be surprised at all if they were looking at bringing the features of this add-on into the main FF codebase. IT'S THAT GOOD, REALLY!

Can't live without this anymore. Minimal yet very configurable.

Absolutely love this add-on! Any chance you can port it to Microsoft Edge Chromium? My company is going to blacklist Firefox in the summer :'(

Awesome! The best addon for productivity, does exactly what I wanted.

Lost some of my open tabs when played around with the plugin right after installation. Besides, that everything works just perfect for me. The integration of Multi-Account Containers is very neat. The STG plugin is just super helpful when you hassle with dozens of tabs

must install this.

Simple Tab Groups: It works.
