Yep. Running Adblock Plus in Firefox will get rid of 90% of the ads out there. NoScript and similar plugins will get the rest.I've got my browser setup with adware blocker, popup blocker, adverts blocker, script blocker. Blocker everything.
It's rare I see an add of any type.
You can control what you see on the net. You don't have to go blocker nuts like I do, but you'll have to take some steps yourself.
