I use Opera, and also FireFox for when I want to download a vid, and they both have add-ons that can help with this. Ghostery, AdBlocker, and AdBlockerPlus are available for both browsers and quite effective at stopping annoying ads and popups.
NoScript is as well, but only offered on FireFox. Give them a try! Makes quite a difference, I must say.
Thank you! I will look into all of your suggestions, some great info!
