using id selectors in Firefox

[gofirst2220]

see title. I was making a modification of someone else's styles for Facebook and it is giving warning such as "don't use ID selectors" even though I was using them because its required for the style. can this be fixed soon?

I don't think this would be fixed: According to CSSLint, ID selectors is not recommanded.

One year later. This issue is still not fixed.
