Mac OS X: Flash and Mac OS X have never lived in perfect harmony, but most of the time Flash doesn't try to hog the processor. When it does, it sucks battery life and heats up your machine. FlashFrozen seeks to avoid this by providing warnings and a handy kill switch for when the inevitable time comes.
FlashFrozen lives up in your Mac OS X menubar and does absolutely nothing most of the time. It's on those unfortunately not rare enough occasions — the ones when Flash eats up every bit of processor it can and refuses to stop — that FlashFrozen is indispensable. You simply click its menubar icon, chose "Kill Flash Plugin", and Flash will die. It works with Safari, Firefox and Google Chrome. You can also have it warn you when Flash is using a certain percentage of your processor so you can get your trigger finger ready on the kill switch.
FlashFrozen is available right now, for $1.19, in the Mac App Store.
