This started happened recently. I haven't installed anything new such as plugins or add-ons; All I've done is update my windows and laptop drivers but I doubt that has anything to do with the situation. When opening certain pages, Firefox just suddenly closes and a "Plugin-Container.exe has stopped working" window opens 4-5 times. Websites include: - Youtube.com - Not the homepage, but the video page. Also note that playing embedded videos doesn't crash, but they don't play. - The Mozilla Support Question Creation page - The page I used to make this question kept crashing.
