I love my Google Toolbar, of course I've had it for months and seach GOOGLE constantly, but the newer version has the best Pop-Up blocker - much better than PanicWare's free Pop-Up Stopper, which wouldn't allow comment boxes unless you manually ok'd it each visit. Google's knows the difference between a comment window poping up, and an ad; also, you can adjust the settings for individual pages, like those M4M dating sites, to allow the personal ads to pop-up. Neat-o!
