Stop Adobe Flash In Your Web Browser!

Because of drive-by infections via malicious Flash files, I HIGHLY recommend stopping Flash files dead in your web browsers until YOU approve them running. I have updated my list of web browser Flash blocking add-ons/extensions:

Safari: ClickToFlash, Plugin Customs

Firefox: Flashblock, NoScript

Chromium: Flashblock, FlashControl, SafeScript (ScriptNo)

Opera: Use the Preferences:Advanced:Content:"Enable plug-ins only on demand" checkbox. Also sort of useful is NotScripts. (Note: NotScripts is kind of a PITA to setup, but works once you have your JavaScript cache set, as prescribed, to 5000K).
