I appreciate the effort of creating this add-on to make up for a lack in FF, but I'm getting a lot of errors with STG.
New groups created randomly with tabs moved in from the groups I set up. My groups disappearing when I delete these new groups. Opening in a random group, not the one I was last in.
I looked for a feature/bugfix request link to add these, but couldn't find one.
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
