Why would you want to do that for? You would still have the annoying ads (or whatever) plus the overhead of a chrome extension to convert them when the page loads!

Clearly somebody who really likes flash ads, but for some reason doesn't like adobe?

Yet he doesn't realize he's supporting Adobe and Flash...

I don't like flash on the web, but I do occasionally run across a site that requires flash for navigation. I thought an extension would be interesting. Also, I have an ad blocker.

If you wanted to be able to drop your Flash plugin I could understand, but Chrome bundles Flash so...hm.
