Firefox has had in the region of 30-40 advisories per quarter recently, hardly an order of magnitude more vulnerabilities than the ~50 you mentioned as the Java plug-in's recent record.

Also, as has been pointed out in numerous recent debates about Java, it might be unnecessary for most folks, but there are still many millions who use it routinely. Indeed, this is precisely why I think Mozilla's U-turn on this issue was a sensible move.
