nice paper on FireFox memory usage reduction

[William Park]

Yeah.  Until recently, I've been using local DNS server to map
undesirable domains to 127.0.0.1.  It was too much hassle to keep on
adding names and their infinite permutations.  Now, I just put up with
it (Ctrl-W in Firefox), or click "Block Images from ..." (Page Info |
Media) if it's too much.
