Is there an app that can move apps back to my SD card?

Firefox, for one, used to be on my SD card until it recently updated. Now the move to SD card button is greyed out. I am looking for an app that can move it back without rooting my phone.

Welcome to Android Central. If you cannot move the app through Settings there is no other way to do that.
