Changes

Note that these add-ons and versions are "pinned" by being held in a compressed file that's hosted in an archive by our test infrastructure and downloaded at test runtime. To update the add-ons in this set, one must provide a new ZIP file to someone on the test automation team. See [[https://bugzilla.mozilla.org/show_bug.cgi?id=1575089#c3 this comment in Bugzilla]].
