i keep having issues with previous session not opening, and normally i can just click "restore previous session" and it returns all the tabs to the correct groups but i had a guy clean my pc today and he didn't restore session before closing and reopening again (which makes the option dissapear). which left me with "reopen all tabs" in recently closed, and not only did it not restore them all, they were not in groups after restoring. well, the extension only made the experience slightly worse but i needed somewhere to vent i guess lol. becareful out there if you cherish your tabs
