Firefox Addon? or grease monkey script? - grease monkey script to remove megavideo limitations

HELLO I recently had a Firefox addon (I think, but could be a scenario), this kind of disappeared on me. Instead, he showed all his chips, small (but bigger) in a pop-up screen ... they can visually see what it was all done () in the case of a clock and remove it quickly open and visually, without, for each chip.

There was a button to the right of all chips, but has now disappeared, and I can not even have the addons section or Greasemonkey scripts. I wonder what it meant. I think I accidentally opened the other day, but no idea how! Thanks for any help if you know that I speak.
