Welcome to the world of men!
In case you have not disabled javascript, you might want to check the "plug-ins only on demand" checkbox. This way you have to manually allow scripts by clicking on a symbol - though this can be a bit "lästig" if you want to watch many streaming stuff.
Furthermore I have the add-ons NotScripts, NoAds and Ghostery running. Never had a bad experience regarding security issues. Even the "naked" browser by itself is pretty good, what I always loved about it, was the ability to block content. See a banner or an ad that ticks you off: rightclick -> block this crap.
I miss this function in real life.
