Hey, I think so (but I didn't go that route), now you either need to wait or use one of the tricks to cause it to update right away.

If I was you I would ignore Mozilla's advice to do it their way and do what I suggested above, of just clicking on the .xpi link and disabling shield studies. It will act immediately, which will give you a better idea of whether or not it will actually work with 58.0.2. I'm not sure it will (I suspect it won't in fact).
