Detect and stop the Flash plugin on command!
Flash animations and videos are among the top processor hogs on OS X. A single poorly-designed Flash banner - even on an inactive window or tab - can eat up an entire processor with its shady mortgage offers.
Your 5-hour battery life gets cut in half, your laptop runs hotter, and your legs cook to medium-rare.
That's where FlashFrozen can save the day.
FlashFrozen lets you stop the Flash plug-in dead in its tracks — letting your Mac cool down and use less power — giving you more time to do whatever it is that you do. Probably blog or tweet or something.
FlashFrozen lives as a tiny menubar app, monitoring the Flash plug-in. It will warn you (by turning red) if Flash is using a significant chunk of your computer's resources. You can then click on FlashFrozen's menu to immediately stop the Flash plug-in.
Any running Flash content is replaced with the broken plug-in message. Want to get Flash working again? Simply reload the page, or go to a new one. The next time Flash is needed, it'll come back to life.
In AutoKill mode, FlashFrozen actively stops Flash content at all times. Turn this mode on and off at will to save even more battery life.
NOTE: On Yosemite and Mavericks, Safari becomes unstable when Flash is repeatedly killed in quick succession, so FlashFrozen's AutoKill mode knows not to affect Safari on these systems. In this situation, please use FlashFrozen's standard mode to kill the Flash plugin. Otherwise, upgrade to El Capitan for AutoKill in Safari.
Works with Safari (on 64-bit Macs), Chrome, Opera, and Firefox 4 & up.
FlashFrozen is ready for El Capitan! (or is it the other way around?)
El Capitan's Safari handles AutoKill great again, so AutoKill has been re-enabled for Safari on OS X 10.11 and higher.

Decent, could be better.
The kill-on-command functionality works fairly well, and I use it occasionally. On the other hand, the AutoKill feature is very spotty and I frequently find it only works for a single browsing session and only after starting the session with AutoKill OFF, then turing it on, then re-loading. Subsequent sessions just don't work and sometimes it will stop working a few minutes into the session. The problem seems to be detecting flash as the message will read "No Flash Loaded" when there are actually several ads going. Viewing the same page with AutoKill off, the Flash is detected, and it can be manually stopped.
Perhaps the developer should think a bit more about the user and build in some functions such as blocking Flash from a particular URL on a permanent or semi-permanent basis. This makes more sense to me than absolutely killing all Flash.
Even when set to autokill flash plug in, it only mutes the sound. The video still downloads and plays.
Developer Response ,
Hmm...definitely shouldn't be the case. FlashFrozen works at the process level, killing the Flash process entirely. It's an all-or-nothing thing.
Keep in mind that FlashFrozen has no effect (and can't have an effect) on native HTML5 video, which is more and more common on the web today, especially in Safari and Chrome, which are now working to phase out Flash.
You can test this by taking FlashFrozen out of AutoKill mode, and seeing if the icon turns solid or red while the site in question is playing video. If the icon stays gray, then there is no Flash content playing.
Flash is the bane of the Internet, and FlashFrozen fixes one of its primary issues. Combined with a strategy for blocking most flash content (like ClickToFlash or simply removing the plugin from your primary browser), FlashFrozen frees you from the issues of Flash taking over your computer. It's not uncommon for a Flash movie to cause a loop in the Flash plugin, burnin' up CPU and crushing your Mac. With FlashFrozen, you know right away, and can easily kill the plugin from your menubar, recovering your CPU and eliminating the issue.
This version supports all of the major browsers for the Mac (Safari, Firefox, and Chrome) so for most this is all you'll need. I'm grateful for it.
(FWIW, my strategy is to eliminate Flash from my Safari browser and use Chrome for all Flash content that I actually want to see. I use the Developer menu in Safari to easily open the same page in Chrome when necessary.)
With Family Sharing set up, up to six family members can use this app.
