When prompted, enter '/Library/Internet Plug-Ins/' and click 'Go' to switch to the appropriate location on your system. To get there, switch to the Finder and select 'Go to Folder.' from the 'Go' menu. Most often, the Flash plug-in can be found in the 'Internet Plug-Ins' folder on your system's hard drive. Whether you wish to conserve electricity, silence overactive cooling fans, boost the security of your browsing experience or protest against the use of media plug-ins, you can easily remove Adobe Flash from your Mac. Personally, my MacBook often sounds like it's preparing for space flight when I visit pages that use Adobe's plug-in.

Back in October, Apple shipped its first MacBook Air models without the Adobe Flash plug-in pre-installed.
