I already see virtually no ads. My setup is Firefox with AdBlock Plus, NoScript, and RequestPolicy, proxied through privoxy.

There are really only two cases where I'd regularly see ads. One was Google text ads. But now that I've quit using Google in favor of DuckDuckGo, I don't see even those (DDG lets you turn ads off).

The other case is seeing some text ads through my email provider, which serves them over SSL -- so they are not subject to being filtered out through privoxy. This is a problem, and I've considered learning javascript just so that I can feed decrypted SSL content through privoxy to filter out the few remaining ads I get through SSL. But so far it's been such a minor problem that I haven't bothered to do so.
