Flash plug in causes Firefox4 (on Vista Business) to hang, on sites with flash content (videos, etc)

I tried everything I found in firefox forums (uninstalling - reinstalling the plugin, disabling hardware accelaration, etc ), but it was useless

I tried installing Firefox 5.0b2 and I have the same problem: with the flash plug in activated, I get CPU usage up to 100% and Firefox hangs...

Make sure that you allow the plugin-container process in the firewall.


You can try to disable the hardware acceleration in the Flash Player.

Thanks for the reply, cor-el. I've already tried these... On pages like: http://www.youtube.com/swf_test.html , Firefox hangs on opening -no time to do anything with the flash player

If you can open the Flash player in IE then try to disable hardware acceleration there. Flash settings are stored in the %AppData%\Macromedia\Flash Player\ locally folder for each Windows user.

I am not sure if this is a Flash Player or a hardware problem. I think it is a Firefox bug, as well... The Flash plugin works fine with Chrome (hardware acceleration enabled or disabled). I also tried Opera and IE9 and everything works fine, too.

Good news: after unistalling both Flash Player 10 Plugin (FF4) and Flash Player 10 ActiveX (IE9) and then reinstalling them, everything works fine for me, at the moment.

cor-el, thanks for the replies!

You're welcome. Glad that you got things working with an uninstall and reinstall.
