How can I use GreaseMonkey to return the "/" key to the browser?

It seems that many web pages use a key /to search. I would like to disable this, because in 100% of the cases I want to use /to search on a page in FireFox. Is there a way to override this behavior using GreaseMonkey or dotjs?

The best public example of this is https://www.github.com/ as well as https://wiki.jenkins-ci.org/display/JENKINS/Issue+Tracking
