It’s getting so that ‘code’ introduced as ‘advertisement content’ is out-of-control. It can hog 50 to 100 megabytes of memory and who knows what can be going on invisibly with the user’s consent.
Java-script and Java itself is getting all powerful and resource hogs.
There has to be software coming out that can throttle down this crud.
I put this on another thread....
You can use “Hostal” (for the Macintosh), too...
http://www.apple.com/downloads/macosx/internet_utilities/hostal.html
It’s a little program that makes it easy for you to handle and manipulate a “hosts” file on your computer... (and this will block web addresses and sites and ads and so on...).
Hosts file

That’s for Macintosh users — but the same thing (a Hosts file) applies to Windows users, too. The key here is to get a good and large list of blocked ad sites and put that into effect on the Hosts file and redirect them all to 127.0.0.1 ... LOL...
And, of course, Firefox has a nice ad blocking feature, too...
