How to Clear Autofill on Mac OS X

Just about every Mac browser has autocomplete (a.k.a. autofill) as a feature. And cleaning up autocomplete in each of these browsers can be a bit of a pain. So today, we'll go over how to clear autofill forms in each of the major browsers the quick way and the not-so-quick way.

The quick way? Using a Mac utility like CleanMyMac X. The not-so-quick way? Doing it manually.
