You click ok and Firefox launches and works fine. Our current version of ESR is 68.3.0, and I know we did not have this when deploying 60.7.1, so somewhere in between it broke.

I have not been able to search any new method or syntax of doing this for the current ESR version, and have not seen any other mentions of this from anyone else reporting this problem in my searching. I suppose it's not the end of the world if we don't set Google as the default search when deploying systems, but it was sure nice having it that way.

Can't you do this via Policies ?
