Upstream issue: https://bugzilla.mozilla.org/show_bug.cgi?id=1601424
Cause is a gcc miscompilation, see https://bugzilla.mozilla.org/show_bug.cgi?id=1601707
There is no patch for this yet. The workarounds in second link are for something else, see last comment ("Thanks. I think dom/localstorage/ActorsParent.cpp needs also some care to get extensions working.")
