Though you can now enable Flash on Google Chrome for Mac, the Linux still doesn't have support. However, if you're willing to run Chromium instead of the official Google build, you're in luck.

Using a current version of Chromium from Launchpad, adding Flash to the speedy browser is a breeze. As detailed here, a couple minutes in terminal is all it takes. Follow the steps, and at long last you'll be able to blow your day in Chromium on Linux browsing pointless YouTube videos and racking up high scores in your favorite Time Wasters!

Personally, the inability to run Flash video and games in Chromium wasn't a major concern. Not being able to utilize Flash-based controls on certain websites, however, was a giant pain in the ass - and it's nice to have that sorted out.
