Sometimes I will leave Firefox for an hour, sometimes it happens as I browse, and sometimes it doesn't happen for weeks, but sooner or later, eventually ALL the tab groups disappear except the one I am currently on. Or rather the tabs disappear, not the groups themselves.
I am not able to find them in hidden tabs, or recently closed tabs.
There is no error, no pattern, no rhyme to it.
