Very promising Tab Groups successor. Edit: After 3 years this had become one of the most irreplaceable must-have extensions for me, and I have to commend the developer for still maintaining it. I'm still baffled why such useful functionality (Panorama) was removed from FF in the first place.
Thanks for your review! Please, update Firefox to latest version v61 and after that update addon to STG v3.0 (not experimental). In this version I implement hide tabs api, switch between groups and not close tabs
