When I exit Firefox, it claims to have one more tab open than is shown. How do I see the hidden tabs?
So far the only way I've found is to wait for the browser to stop responding and then when it asks to restore the session can I see and close one marked as "Sandbox". I have tried ctrl + 1-8 and that doesn't show it.
I had the same problem. I made a research through my add-ons and then disabled 'Download Youtube Videos as mp4' (ver. 1.7.18) That resolved the problem.

It happens only on my LJ and I suspected it is because of YT video I posted. Yesterday I made a new backup LJ community to see if another YT link will cause the same. It didn't though. So today I reposted the same video from my main LJ and the problem occurred here too. The only difference between two YT links (the one from yesterday and the one from my main LJ) is that the previous clip was old and today's one is new. So probably the new html5 thing may be the reason.
Originally I see an "image" of the YT clip and a button to play it. When open tabs with Ctrl+Shift+E and close the .js tab manually the "image" of the clip disappears.
