Personally, I used to purposely not install Ad Block / NoScript because I realize that the folks that offer on-line content "free" need some form of revenue...
However, once they started all sorts of Java/Flash/etc. junk to force you to pay attention to ads (wipes/blinks/delays/pop ups/pop unders/sound/loading adware/tracking ware/software/spyware/etc. and just about anything else they believe that they have a right to on my computer--I switched to FireFox and (a bit later) locked my machine down tight.
I still have a few pangs about not supporting "ad supported" content--but they did it to themselves.
Now, with cookies blocked, java blocked, ads blocked, scripts blocked, except for those few sites I white list--I am back to the browsing experience of 10 years ago (few ads, no pop ups/unders, no spyware, etc.).
