If you have problems with current Shockwave Flash plugin versions then check this:

  • see if there are updates for your graphics drive drivers

  • disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)

  • disable hardware acceleration in the Flash plugin

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window

If you use a non standard windows theme or made other appearance changes then try to revert those changes and use a (different) standard theme or Windows wallpaper.
