If you run Firefox (or any of the forks), run uBlock Origin. Many ads are malicious. If a site won't open or won't function properly because you're using an ad blocker, leave the site. It really is as simple as that.

@Chad McCullough Great advice!

Consider adding JShelter and Privacy Badger to that. I've used that for a few years now, and I'm very happy about the avalanche of crap it keeps out.
@hans Yes! Excellent point!
