Here's a very useful feature that has been recently added to the Chrome/ium dev channel builds: an option you can use to set the plugins to "Click to play" (which is basically like a built-in Flashblock for Chrome). Using this option, Flash (and other plugins) content will never load until you click it.
This feature is very useful if you're using an old computer or a netbook/laptop running on batteries (since Flash uses a lot of the battery).
To enable "Click to play" you'll need the latest Google Chrome / Chromium dev channel; then go to Preferences > Under The Hood > Content Settings > Plugins and select "Click to play". Below this option, there's an "Exeptions" button you can use to whitelist/blacklist websites.
