All the incognito browser windows share the same “session” in Firefox. So say you open an Incognito window to browse Facebook or something, then you open another Incognito window, this new incognito window is linked to the previous incognito window, meaning you are logged into Facebook at that new Incognito window as well. This is because, as I explained before, all the incognito windows share the same “session”

The only way to clear incognito window is to close ALL of them and then create a new incognito window. You dont have to close the main non incognito Firefox window though, just close all the incognito windows. Then open a new one, now your previous session is destroyed and you are new again.

You may know it but its not that common knowledge as it should have been

    If you want every tab to have its own session use temporary containers

          Do you know if this is available for Android’s Mull?

          I’ve tried looking for the option but haven’t found it.

            Can’t say I’m familiar, sorry

            I’m pretty sure it would still be implemented at the engine level for mobile but AFAIK at least the regular mobile Firefox has nothing for it in the frontend

              No worries! Thanks for getting back to me!

              It would be pretty cool if Mull did this as well, surprised it doesn’t.

        Yes it really would been. The temporary is not updated for 3 years so that is quite abandoned.

        Firefox some native but they feel more a solution to keeping data you want separate from each other instead of just having a way to isolate then remove.

          And it works with hidden tabs, and thus by extension, with the tab groups add-on.

          I have a whole group of tabs for uploading add-ons that have their own session, and the group’s behavior is persistent. And I can switch to them on the fly. When not in use, I don’t see them there at all.

            I need to twiddle some settings. I can’t get the exact behavior I want yet but I’d like to do pretty much what you are.
