I also tried to add these, but they caused failures:

not serialized this way?
  overflow: -moz-scrollbars-none, -moz-scrollbars-horizontal, -moz-scrollbars-vertical

relative things:
  font-stretch: narrower | wider
  font-size: larger | smaller

Maybe leave the existing last invalid_values  and add your new one (background-color)?

Your final initial_values entry for color is wrong; please remove it.  It's a bug that we clamp rgb() to 0-255.

-moz-use-system-font as an initial value for 'font-family' is also kinda wrong; it only comes out initial when there's no system font in the 'font' shorthand, so I wouldn't include that.

All those new other_values for font-family are pretty weird -- you should at least have a code comment explaining that for font-family (unlike font) they're not special values, they're just identifiers -- and maybe use some that aren't -moz-* 

r=dbaron with those things fixed

-moz-scrollbars-none ought towork (synonym for hidden), and the other two also ought to work once we implement two-value 'overflow'.  What failed?

We don't implement these, and they were dropped from the spec.  Could test them in invalid_values, though.

>   font-size: larger | smaller

I'd think they'd have worked as other_values.  What failed?

The new test is stronger, since there's only one reason to reject the input.

I see.  I'll leave it out, and let you add a more correct test in bug 515919.

When there is *not* a system font?

Anyway, this doesn't seem to fit in property_database.js, so I'll teach my fuzzer about it instead.

Oops, they should have gone in font rather than font-family.

I'll stick "-no-such-font-installed" in font-family as the "just an identifier" test.

You're right, -moz-scrollbars-none does okay.  I'll just add that one for now.

>>   font-stretch: narrower | wider

That would explain it!

>>   font-size: larger | smaller
> I'd think they'd have worked as other_values.  What failed?

Yeah, I assumed incorrectly based on the font-stretch results.  Added these.
