Comment 239 for bug 727064

a glitch with an unsupported (upstream) version of an unsupported (by us) third-party plugin does not qualify for any kind of 'urgent' status by any stretch of the imagination, I'm afraid.

running the 64-bit Flash plugin is just generally a bad idea, because they never keep it up to date with the 32-bit one, so it's always vulnerable to several known serious security issues. And 'known serious security issues in Flash' is really not something you want to be exposing your computer to. Just run the 32-bit version, really, you'll be doing yourself a favour.
