I'd like to have the oportunity to filter some sites. In this case there is an ad http://storage.netinfo.bg/Banners/1331/Copy%20of%20rollover.swf? and I'd like to filter this site.
This is a good feauture to filter unwanted content.
If there is an oportunity to disable mozilla plugins for some sites this also can be a solution.
I'd like to have both of these feautures implemented.

Reproducible: Sometimes

Steps to Reproduce:
1. Load the site
2. reload few times and you'll see the unwanted banner.
3.
Actual Results:  
http://storage.netinfo.bg/Banners/1331/Copy%20of%20rollover.swf - unwanted stuff to be filtered.

Expected Results:  
I'd like that Firefox filters the unwanted site for me.

For now I've filtered it in my own proxy server configuration. But I'd like to have this feature at my work - there I don't have administrator rights to filter web content.
