The version of Firefox installed on the remote macOS or Mac OS X host is prior to 84.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-54 advisory. Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
