It might be a solution - albeit painful - but more largely I think the problem is somewhat different, whereas before sites didn't support FF because they didn't really know FF because it was new, now it seems they don't support it because they don't care anymore. I don't know what the appropriate solution is but if I were the FF team it would worry me at least as much as anything else. I see this as a long-term threat.
