Chrome:plugins, disable Adobe Flash Player

Adobe Flash Player plug-in - Google Chrome Help:
"Enable or disable Adobe Flash Player

Type chrome:plugins in the address bar to open the Plug-ins page.

On the Plug-ins page that appears, find the "Flash" listing.
To enable Adobe Flash Player, click the Enable link under its name.
To disable Adobe Flash Player completely, click the Disable link under its name."

There is also chrome:about for many more hidden options.

Flash plugin is still a major reason for frequent Chrome crashes,
excessive network usage by annoying ads...
So until they figure out to utilize HTML videos for ads, disabling Flash could help.
