When performing add-on updates, certificate chains terminating in
non-built-in-roots were rejected (even if they were legitimately added by
an administrator.) This could have caused add-ons to become out-of-date
silently without notification to the user. This vulnerability affects
Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0.
