Good afternoon, We have a large quantity of PC's that we need to add a Pop-Up exception to for Firefox. Is there a way to add this desired website pop-up exception via a script remotely? I know where to go to manually add a Pop-Up exception (Settings/Privacy & security/Allowed Website Pop-Up's). But is there a way to script this? Can this even be locked with a PrefLock line in a Mozilla.cfg file? I did a little digging and did not see anything. That would be ideal. Any suggestions are greatly appreciated! Please note that the remote machines are NOT a part of a domain. But I have complete connectivity to them as an administrator on the same network.
