Is there a way to permanently disable Infolinks from my browser?

I really hate the Infolinks service. It’s the service that highlights words on various websites, so when you scroll over the word, “more information” about that word appears.

(To see what I’m talking about, go to www.writesomething.net and notice the highlighted text).

Infolinks appear on many websites.

Is there a way to disable it, so it never works on my computer?
