--- Comment #1 from Kai Uwe Broulik <k...@privat.broulik.de> --- Looks like Waterfox doesn't like calling window.postMessage(foo) with just one argument. It requires the targetOrigin argument. Patch: https://phabricator.kde.org/D23568 Technically a bug on our side caused by poor docs, lack of my reading skills, and lenient behavior on browser side. Note that Waterfox isn't officially supported by us. -- You are receiving this mail because: You are watching all bug changes.
