Flash cookies, also known as Local Shared Object, is a data file that stores and records your information on your Mac computer. For example, if you are playing a Flash game, then your score, achievements are automatically recorded in a Flash cookie.
It’s not just the games but even your personal information including password and user name are meshed together in a Flash cookie. For some, this can ruin their privacy.
However, not all Flash cookies are bad — YouTube cookies, for example. So, before you remove the Flash cookies from your Mac computer, know that cookies can be used for legitimate purpose, too — in online net banking, for example.
That said, if you are using Mac OS X Lion or Snow Leopard on your Mac Machine, here are a couple of ways to get rid of Flash cookies easily:
To avoid cookies storing automatically on your Mac, follow this procedure:
When you are playing a Flash game or running a Flash video, right-click on the Flash content and select Settings, which will pop up a window.
Navigate to the Global Storage Settings where you can uncheck “Allow third-party Flash content to store data on your computer.” You can also specify the amount of disk space a website should use. If you don’t want any website to store Flash cookies on your Mac machine, then swing the scale to 0KB.
Mac Mozilla Firefox user can download Better Privacy, which is an addon to prevent website from invading your privacy. It lists the cookies, blocks flash content, and leaves it up to you to decide whether to store or delete flash cookies.
Google Chrome users can download Click & Clean extension to get rid of the Adobe Flash objects and cookies. It also scans your Mac for Malware, erases temporary files and clears Flash cookies in a jiffy.
Flush.app is an app from Machacks that lets you preview the flash cookies stored on your iMac, MacBook Air, and MacBook Pro. You can instantly flush and delete the flash cookies from your Mac.
Download Flush.app — works fine on my Mac OS X 10.7 Lion.
Lastly, check out CCleaner for Mac, which is yet another well-known utility for deleting Flash cookies that are hidden under the Adobe Flash Player. You can also delete individual cookies, clean the cache, Internet history, uninstall application from your Mac and do a lot more with this free tool.
