Yep, discovered Firefox doesn't copy styles the same way as other webkit-based browsers like Chrome/Safari. Working on a Firefox extension which will solve all this, but even that has been a ton of quirks to deal with. 7% of my visitors used FF, 20% Safari and 66% Chrome, so I think my prioritization so far made sense. Will keep you posted on an FF extension.
