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.

Really useful space saving ability to organise interests. I wondered if accumulating so many tabs slowed browser down.So disabled it and deleted them all after doing a json backup. Slow speed is not caused by this so renabled and restored the groups. How to donate or fund the writer?
