The best thing about iCab is the amount of filtering it lets you do. You can selectively enable plugins, and choose which MIME types to pass to them; Filter Java applets by URL; Block images by server and by image size; Say which servers get to set cookies (and ban images from setting cookies); And best of all, apply permissions to javascript letting you forbid scripts from opening new windows, writing in the status line (Adios annoying scrollers), etc. This can be done by server, so you can avoid all those nasty Geocities popups, while at the same time, allowing the preview windows on to appear.

All this is why iCab are getting my $30, and I will probably never go back to Netscrape.
