Try starting Firefox with a new user:

Thanks for any help!

You need to look further down to "Changes Over Time" to find the "Mac Directory Change" section where you will find the path I posted. 

Mac Directory Change

Due to Apple's stricter approach to software signing, as of about version 35 or so configuration files should now be placed relative to /Applications/Firefox.app/Contents/Resources (so mozilla.cfg should go there, and autoconfig.js under /Applications/Firefox.app/Contents/Resources/defaults/pref.)

mozilla.cfg needs to be in this folder on Mac:

  • /Applications/Firefox.app/Contents/Resources

I'm unable to test this at the moment, but can you document it for me? According to the "Deploying Firefox in an enterprise environment" document at https://developer.mozilla.org/en-US/Firefox/Enterprise_deployment:

Create a .cfg file in the Firefox program directory. By convention, mozilla.cfg, but it can be any file name really.

which I take to mean the directory that contains "firefox.bin", as Step 1 in that same document says:

Find the Firefox program directory where the Firefox executable is located. For example, in Windows this is typically either C:\Program Files\Mozilla Firefox or C:\Program Files (x86)\Mozilla Firefox in macOS it is typically /Applications/Firefox.app/Contents/MacOS

Thanks!
