More tabs open than I can see
Apologies for the strange question description, it's an odd issue to describe.
Basically, when I close Firefox, it brings up the "Exit and close tabs?" dialogue. What's odd about this is that it says "You are about to close 45 tabs" despite me only having 5 open (4 pinned tabs, and one additional tab).
Anyone have any idea how to see the mysterious ghost tabs?
Additional information that may be relevant is that I used to use the old Firefox feature that allowed you to organise tabs into individual groups that you could select to just view those tabs, then switch to a different group, from within one browser instance. I'm thinking that when the feature was removed, the tabs that were still open within the 'hidden' groups stayed open, but not visible. If so, any idea how to access them?
Thanks to anyone who reads this, and extra to anyone who can help!
