So the userContent.css is post filtering the data being displayed after it's downloaded - similar to what some GreasMonkey scripts do? I was thinking it was also reducing the downloaded data... I need to do some tests.

Also, if I have a 50K host file doesn't the browser have to check every link address with the list before sending it out to the internet DNS? I was thinking about the time taken to perform this check.
