One of my favourite apps to avoid using is Adobe Flash. There are large security, performance and battery life benefits. I do not have flash installed on my OS X and used
When I must have Flash, I use Google Chrome because a Flash Player is built into it. But switching to Chrome can be made very simple with this app.
I am quite enamoured with this method of being mostly Flash free on OS X. So, I created Eject to Flash. Installing it will allow you to open the page you are viewing in Chrome with one click or keyboard shortcut (Command + E). Since Chrome comes with its own Flash plugin, you can remove the system wide plugin and run Safari without Flash. Enjoy.
