Hi, tab groups on Chrome/Edge really help me in my work. Once one subject is complete, I close all the related tabs. But I am a Firefox user. I do not want to move to a Goggle or MS product that wants me to sign in and collate all my data in one place. I do not want to use a plug-in - I trust the code that Mozilla writes but struggle to trust code that a third party writes and also has a "Not monitored by Mozilla" banner. As FF had this feature in the past, are they adding to the roadmap to bring it back in the future?
