This suddenly started happening about 15 minutes ago. I didn't add anything to Firefox or change any settings or anything, it just happened out of the blue while I was in the middle of watching a video. Whenever Firefox attempts to load anything that uses Flash it immediately crashes. It happens in Safe Mode too, so I know it's not any of my add-ons. I've already got hardware acceleration disabled as suggested to other people who have had the problem in the past, and attempting to disable the Flash plugin causes a crash as well (and it's turned on again when I restart). Fortunately I can set it to "ask to activate" to safely visit any page I need to, which allowed me to make sure I had the latest version of Flash (it didn't help), but it's still obviously a problem. I've got a full-scale virus scan running right now just in case something's screwing with me but I'm hoping there's some sort of other easy fix for this. Any ideas?
