So I have GreaseMonkey installed on Firefox, and I use Platypus in a minimal way to make some web pages look the way I want. Of course, the thing I wanted most was to get rid of ads, which Firefox's popup blocker and AdBlock take care of adequately.
(BTW, if you didn't know about the adblock list maintained at http://www.geocities.com/pierceive/adblock, you do now. Get it and it'll make your adblocking simpler and more complete. (Wow, do I sound like the Emperor. "And your journey to the dark side will be complete." (Evil grin)))
But no, I want one more thing. I want to have control over redirects. When I log out of hotmail (I have a spam magnet account there), I don't want to be re-directed to msn.com. And when I finish using my webmail account for $WORK, I don't want the next refresh to go to the ISP's advertising page.
I'm not bitching, I'm planting ideas.
