So far this has been the BEST Firefox tab grouping add-on I've found. I must say that I was really looking for a chrome-like tab grouping addon functionality. Grouping tabs by color and quickly group and ungroup them was the only I was looking for, but for some reason it's hard to find.

For me, FF is a way better browser than Chrome and its chromium-based alternatives, but I must say when it comes to tab grouping, FF is ages in the dark.

Tab trees with their own panels, addons capable of coloring tabs which will not actually get colored, but rather the subtabs within another Tab Trees addon, more different panels with stylish presentation of tabs as if I was using Canva or PowerPoint (I'm clealy referring to Panorama) were among the issues I was facing on my journey to find a simple and clean tab grouping addon.

Fortunately I've found this one that doesn't actually does what I want (which was grouping them in the tab panel at the tome by color), but also does it amazingly by packing them on the backend, and you can quickly switch between your tab groups by clicking on the navigation menu, or setting up your own shortcuts.

It also gives you the possibility to customize the group names, colors and even icons if you want.

I must really thank you guys for this addin which I came to understand that it's even better than the way it's done on Chrome.

This feature is really important to me and I was almost quitting using Firefox due to the lack of decent alternatives.

This addon is even better.
I highly recommend giving this one a try!

Good

This is the extension I was looking for a long time, it's like Chrome tabs, but even better. It saves a lot of time in my work and leisure. And it works even in the Firefox Developer Edition :)

Today the extension somehow lost track of all the tabs in my groups (~50 tabs). I just had to restore an automatic backup created by the extension to fix the issue.

Bugs will always be there, good software makes them a lot less annoying.

Keep up the good work!

This extension is so pleasant to use.
Thank's !

It is incredibly well-made, highly functional, and extremely convenient to use.

I wish I knew this add-on existed before. I cannot do without it anymore. Exactly what I needed, great design, and free!
On of my essential add-on now.

Great add-on and a very good organizer. Even better than similar features in Chrome or Edge.

Outstanding extension for saving tabs! Simple Tab Groups makes it extremely easy to save tabs, while also organizing them to your liking. If you're using Firefox, this extension is a MUST HAVE.

I was really happy with this add-on but for a few days, it detroys Firefox. Incredibly buggy and makes FF work like a snail. Need some work I guess.
