If you feel you'd rather live without Flash, a search turned up

Apple sells far more iOS devices than Macs, and no iOS devices support runtimes for Flash content. That has had a major effect upon advertisers, publishers, website design, and online video broadcasters, who have collectively made monumental shifts away from Flash. This in turn has made Flash playback far less important on the desktop than it was just a year or two ago, although there is still important content tied to Flash.
