This document discusses Chrome blocking Flash by default due to security and processing concerns. It provides instructions for allowing Flash on specific sites like Wixie and OneMoreStory. To do so, users control-click a Flash error, go to Settings > Advanced > Content Settings, and add the sites to the "Allow" list to enable Flash for just those sites. The document warns that some sites require the specific URL rather than using a wildcard domain exception.

The problem with Flash
● Flash is processor intensive
○ Can bog down browsers and machines
● Prone to malware and virus attacks
● Constant updates
○ Sometimes as many as 2x a month
● Flash use to be an industry standard but due to
persistent, and recurring, security flaws as well as
better technology allowing for high quality
graphics with less processing power, Flash is
going away forever in 2020.
