Flash Player does not load flash objects and brings performance to a crawl in firefox. The space where there should be Flash content is blank, and the task manager shows Flash trying to launch over and over. The tab that this is occurring in becomes unresponsive, but the browser doesn't report that Flash Player has crashed. I've tried reinstalling, clearing cache and files, and enabling/disabling protected mode in Firefox, but none of those have fixed the problem. Because I can't get flash content to load at all, I can't disable hardware acceleration.
The standalone flash player (the flash player projector from Adobe Flash Player - Debug Downloads) also fails to load SWF files at the same time. It just has a blank white appearance, the same as if no file was loaded.
