Watching Full screen YouTube in FF under Win 7 with over 10 tabs in a darkened room I pushed something and the active Tab got muted and the whole win task bar disappeared from the bottom of the screen. Also FF Tab line disappeared, that I could get back by moving the mouse over the top of the screen, but only scrolling the page to the top first. When I selected an other Tab, everything was fine. I couldn't fix the the YouTube Tab behavior after several FF restarts either, No task bar, no TAB line and no sound. I was quite desperate and searched FF support page for a while .

Later (after a break) I realized that the Tab had the muted icon, pushed it and that fixed all the three problems at once. Pushing Ctrl M does not reproduce more than the Muting. Is there a known shortcut producing this "effect"?
