No. The browser tries to do a host look up through the proxy (am i right here ?) so u could block ads even there. Also if the url is cut out from a page the browser doesn't need to do a host look up. cpu cycles saved !

I had tried one such list and presto! it wouldn't block the ads on indian sites.

If just 0.0% of my processor is being used i don't really mind. >You have to install it don't you?

I would aswell maintain such a list in my mozilla blocklist then. No hostlookup then ! >there's overhead in starting a new process, and in >running that. how much ? cpu usage for bfilter is nearly 0% as i see it right now and memory usage is 200kb, not bad eh ? Another issue with host blocking. What if a file that you want is on your blocked host ?? other than the simple image that you were supposed to block ? host approach fails there. Image blocking would do some good if u were using mozilla. There are some tradeoffs in each approach, for my purpose bfilter fits the bill.
