I only allow scripts to run a very trusted websites, and never on newly discovered ones. I don't see ads I don't want, and and not nervous about visiting new sites, because I know they can't run scripts without my permission.
I blacklist as many ad services sites as I run into, and several google ad services as well.
With all this tightened down, I rarely--if ever-- see the same issues other people have complained about.
Thank You for the reply. And Thank You for teaching me something.
I use Waterfox with AdBlock Plus and NoScript. Never have issues.
