This even happens on legitimate websites like facebook. I have disabled all of my plug-ins, restarted my computer, and they still show up! These weird double underline links are not showing up with Safari. What do I do to get rid of them? Someone else asked and was told to put on the "ad-blocker" ad on, but that still didn't work.

Usually this is due to an extension that contains TextEnhance code. Did you disable the extensions as well as the plugins? Note that the culprit may not be obvious.
