The test that you pointed to is for the Shockwave Player, which is different from Flash Player. Would appreciate some help to get this error permanently resolved. This problem was causing Firefox to crash, but Firefox is now stable- only receiving the flash error messages. I've tried most of the fixes online: disabling hardware acceleration (works for a few hours then the problem comes back), uninstalling then reinstalling adobe flash, shockwave, & silverlight (worked for a few days, now the problem is back), clean install of Firefox, changing flash permissions in Firefox to ask to activate, and all the fixes listed here: Flash Player games, video, or audio don't work | Windows.

The server encountered an error while processing this request: On the Adobe test page: Adobe - Test Adobe Shockwave Player I can see the Shockwave Flash test message, but get the following error message when trying to view the Flash Player test: Internal Server Error I keep getting the error messages: 'Adobe Flash Player 14.0 r0 has stopped working' and 'Unresponsive Plug-in: Shockwave flash may be busy or may have stopped responding.' when trying to watch videos from youtube, hulu, netflix, etc. Hi, am running Flash in Firefox on Windows.
