Kirk,
You're right. I did use the words in the link you posted to search for related information.

Long ago, I tired of clicking on search results that repeatedly turned into advertisements to subscribe, like the WSJ's. So I began using a low-level fix - editing a file on my computer named "hosts". I use Windows, but all OSes that access the internet have this capability.
Here's my entry in that file for the WSJ:
"127.0.0.1 wsj.com # Unsubscribed - 4x cost of NYT and 8x WaPo"
The 127.0.0.1 is the address of a simulated DNS server, that does nothing but return a message indicating that the URL doesn't exist. "wsj.com" is the URL you want to block. And every thing to the right of the "#" is a comment.
-------------------------------
Because of this, when I click on a link to the WSJ, I get:
"Unable to connect
An error occurred during a connection to www.wsj.com.
The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web."
-------------------------------
I edit my "hosts" file by hand, but it's a bit cumbersome to do it this way. If you're not a techie and want to do something like this, you should probably use a utility. Here's a few from a well-respected tech site. But I haven't tried any of the utilities they suggest.
