Mozilla upstream didn't reject the bug, the bug was rejected in the Firefox product on Launchpad, which is technically upstream of the Ubuntu/Firefox product. It's a particularly confusing feature of Launchpad's.
I don't even think that a bug has been filed for this in the Mozilla bug tracker. Would someone like to volunteer to take care of this?
