Welcome aboard.
There are lots of great ways to get started. You can take a look at some
of the Projects Of the Week, or POWs, at

Also, bugzilla is full of reports of various problems. In each case I have
isolated the problem so that they should be easily reproduced.

Better yet, if you already have something in mind, go for it.
