This is the best that ever came after Firefox killed the integrated TabGroup feature. Just wondering if there could be the option to set a shortcut key for backuping your tab goups to a json file?
Thanks for your review! In future versions I will make sync tabs by FF sync account 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
