Firefox review

I downloaded Mozilla Firefox yesterday and starting using it. One amazing feature that I found about the browser was that I can block specific images or parts on the webpage of a particular website which you find obnoxious while reading articles. You can simply right click on an image and click on "Blobk images from an ip address or a domain name". And course you can anytime go in Options and enable the blocked ip addresses and domain names so that images residing in those addresses can show up again when you visit the web page again. The only problem here is that, the blocking is address of image folder based. Hence all images residing in the folder say 'shopping.indiatimes.com/images' would get blocked.
