This is really annoying. I've had that feature disabled since I first started using Firefox as I feel it defeats the purpose of incognito tabs to make it obvious when you have them open, and I prefer keeping all my tabs organized in a specific way I've checked about:config and that feature is still set to false, I've checked about:studies and there's nothing that looks like it would impact private browsing. I've tried restarting both Firefox and my computer, the tabs are still separate Anyone have any ideas on what to do now?
