Workaround
This is how I fixed it.
Instead of putting my addons here /Library/Application
Support/Mozilla/Extensions/{ec8030f7-c20a-464f-9b0e-13a3a9e97384}/
I created two directories
mkdir /Applications/Firefox.app/Contents/MacOS/distribution/
mkdir /Applications/Firefox.app/Contents/MacOS/distribution/extensions/
Created the distribution.ini file
vi /Applications/Firefox.app/Contents/MacOS/distribution/distribution.ini
[Global]
id=fx4myorg
version=1.0
about=Firefox for My Organization
[Preferences]
extensions.shownSelectionUI=true
extensions.autoDisableScopes=11
I placed the extensions in
/Applications/Firefox.app/Contents/MacOS/distribution/extensions/
All I good now and works for like
