The Domesticated Primate

I broke down and figured out how to write a Firefox extension. Nothing really fancy; it just lets you check/uncheck all checkboxes that you currently have selected in Firefox. The only reason for this is when website designers don't put a check/uncheck all button on their page, but it sure is something I've wanted when they don't. Your mileage, of course, may vary.

The Firefox extension is called QuickCheck.
