Hi. Etrecheck is a cool Mac program but does it offer any more info than that? I know it's supposed to report adware hiding in the system & run a diagnostic system check. But if it did say that about Firefox, it should have given a little more information as to why it said that.

Please let us know. Very curious to see why it said that. Maybe you can post a screenshot of the report or copy & paste the full message it said about Firefox. Thanks!
