May not be able to add a category without changing code bits to match. We could move the "security" changes into "Other" for purposes of this patch if necessary.

How is "XUL" front-end? Not that we've had security bugs in there for a long time since it's no longer exposed to the web, but if something was broken in there it'd be bz or smaug or peterv or some other deep document guy who'd get thrown in to fix it. That's not the component for "things written in XUL", but rather XUL itself.

If you kick out specific "DOM:" components like DOM: Animations then you will have to explicitly list all the other DOM components in the DOM group. DOM% will still match those and then bugs will get double-counted. It'd be easier to fix the names of the bugzilla components first (there's no reason "DOM: CSS Object Model" couldn't be "CSS: Object Model" if it's not related to DOM).
