 Mozilla recently blocked remote jar files by default:

 https://bugzilla.mozilla.org/show_bug.cgi?id=1215235

 Then they had to re-enable the remote jar files again in the release,
 because users of IBM iNotes (some sort of webmail thing) ran into an
 incompatibility.

 https://bugzilla.mozilla.org/show_bug.cgi?id=1255139

 In any case, Mozilla's intention is to block by default again in the
 future. So when that happens, if not sooner, we should ensure that our
 security slider is not re-enabling remote jar files at Low Security.
