Why don't you grab the Firefox source code and fix the bug? You're in the perfect position to do so: the bug affects you daily, so you won't have to do anything special to reproduce the problem. You'll also be the one who is most satisfied to see it fixed; you'll be scratching your own itch. You've probably also overestimated the difficulty of getting the patch committed.
