Hmm It appears HCL added Firefox for Mac to the Updates for Mac Applications…
Fixlet # 20750000 on 4/7 using the source of Firefox…
Unfortunately it doesnt take into account that there is an ESR version as well … So its missing the relevance to detect it… It should have
(content of file "/Applications/Firefox.app/Contents/Resources/defaults/pref/channel-prefs.js" as lowercase contains "%22app.update.channel%22, %22release%22")
added and also the Source should be changed to Mozilla to comply with the existing Firefox for Windows…
