What will be loaded if I click the "blocked" icon?
 

My global site preferences block files from third-party sites, which does a good job of eliminating ads and other things I don't want/need.

I just turned this blocking off for a new, safe site. A few pages later, the "something has been blocked" icon appeared in the status bar, causing me to ponder, "I wonder what's being blocked?"

Is there any want to see a list of files that have not been loaded?

The error log will display a list of everything filtered out by ad blocking.
