I need to block Flash plugin by default and only allow it on manually approved sites, while allowing the PDF plugin to run anywhere automatically. Is it possible to achieve?

I use FlashBlock - does exactly what you've described.

Honestly, my knowledge of permissions in Chrome is a bit... lacking. This sounds like something that should be done in your firewall... and not at a workstation level. In most firewall appliances, it's fairly easy to block certain mime-types & such on-the-fly and white-list some sites. The advantage to this approach is that even if a user switches to IE, Opera, Firefox or whatever else to access whatever annoying flash site... they're still unable to get there.

I have to disagree, this has nothing to do with firewalls. It's not like I need to keep my network's users at bay: I only want to reduce CPU usage at my own laptop. So while I theoretically can switch browsers and while I technically can compose iptables rules to block incoming Flash rules, that would be a crotch rather than a simple and elegant solution. FYI, the opposite of what I need (blacklisting/disabling a plugin) can be easily done in Chrome config. – dpq Aug 31 '11 at 20:31
I understand now... I thought you were shooting for a network of users... not a 1-off on a roaming laptop. Using iptables to block http-traffic based on the content of the stream is even worse though. I agree that this is a very good question. – TheCompWiz Aug 31 '11 at 20:34
And oops! I really meant 'crutch' there. :\ For some reason I can't edit my own comment here although I can do it on StackOverflow. – dpq Aug 31 '11 at 20:43
