Breitbart is buggy for sure. So is Daily Mail. I switch to google chrome on those
I don’t get any ads or spam when visiting Breitbart or other of those ‘loaded’ sites.
Use Chrome, and install the Ghostery app.
The Ghostery App allows you to shut down advertising, trackers, beacons, widgets, social trackers like facebook, etc.
The only thing that runs on Breitbart for me is ‘disqus’, that’s the only one I allow to be running on that site so I can comment there.
Chrome is far superior to IE, I haven’t used Firefox in years.
