Comment (by gk):

 Okay, with `bug_30380_v3` (https://gitweb.torproject.org/user/gk/tor-
 browser.git/log/?h=bug_32380_v3) I get the following build issue:
 {{{

 Our toolchain is fine in that it can compile the respective code from the
 canonical
 [https://treeherder.mozilla.org/#/jobs?repo=try&revision=f315fe26d1731d325eb8981a5bfe7e7c819842fd
 try push]. It seems we have the problem that the patch for
 https://bugzilla.mozilla.org/show_bug.cgi?id=1547063 did not land on ESR
 68.
