I just love, love, love the ability to put all my different research/interests/archive into groups.

It's awesome ! Really helps to manage >100tabs. Thank you so much!

I love it. I'm using it to create different areas for my work env. I have stuff to read, docs to follow, and current worspace etc. This extension is excellent, super stable so far.

Exactly what I was looking for. Allows you to load a group of tabs in the current window and flip between groups without any problems. I only wish there was an visual way to identify which groups are currently loaded without clicking on the menu button.

I can't explain how I've survived without this extension before.... This is perfect extension that is helping me on daily browsing, and daily tasks keeping everything organized and handy. It also saves a lot of space on the nav bar. This should be the default approach on Firefox, while it comes to browsing experience, but I am glad that this extension does the job perfectly. Well done Drive4ik and contributors, well done!
