Rated 5 out of 5 stars
I like being able to choose which Flash objects I want to see on a page. The whitelist is a good thing to have for those few sites where you always want to see Flash (YouTube, for instance).
Just one thing to be aware of: occasionally, a Flash object will try to load other Flash, which doesn't work because they get blocked. But there's nothing to click on to say, "I want to see these too", so the application ends up not working. I find in these cases it becomes necessary to whitelist the site, at least temporarily.
