I am using my hosts file to block ad-serving domains like

FireFox fills the blocked ad containers, be they frames or divs or whatever, with a page that says:

Unable to connect

Firefox can't establish a connection to the server at .

* 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 would like to replace this with something less ugly. Is this possible?

I am running XP and FF 3.5.
