Now that Accepted is working in 202, I've grabbed the mozilla source code with
Mercurial so that I can work on it in a Linux environment.  I've also started
looking at more bugs on firebug
(https://bugzilla.mozilla.org/buglist.cgi?quicksearch=sw%3A[good%20first%20bug]&list_id=1252429).
It's surprisingly difficult to find a bug that
seems like I can fix it that doesn't already have people working on it.  (It
seems people sometimes neglect to remove the 'NEW' status from them).
