iirc, Firefox will block flash from working when it knows the plugin is vulnerable. flashtester.org works today, but not last week and maybe even the week before. i have seen this behavior a few times after major security flaws are known to be exploited. i don't think i did anything to fix it except apply updates and reboot. Have you rerembered to make sure no firefox process or any flash process is running? $ rpm -qv firefox flash-plugin firefox-10.0.7-1.el6.centos.x86_64 flash-plugin-11.2.202.238-release.x86_64 FlashTester.org succeeds but javatester.org fails, so ... Tools --> AddOns --> Plugins --> "Check to see if your plugins are up to date" which brings one to https://www.mozilla.org/en-US/plugincheck/ "Missing Java? For your safety, Firefox has disabled your outdated version of Java. Please upgrade to the latest version."
