 So far, they have tried reinstalling, we confirmed the permissions on the
 directory that the browser should be installing to are accurate:

 They have also tried disabling XFence / Littlesnitch, clearing their
 routing table and entirely restarting with the previously mentioned
 software disabled. There has been no change in the behaviour they are
 seeing after trying these different things.
