FINALLY A PLUGIN REALLY THAT WORKS!!! As a web developer, I have like a million tabs open at the same time and this feature is a MUST HAVE to allow me to group tabs! (I started grouping tabs before Firefox added the feature, so I move to firefox feature, then they removed it and I started using a plugin but It stopped working .. was missing this feature untill now)
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
