The Mr. Robot thing was not "malware". It was an easter egg, just like about:mozilla. You may say it was poor taste on Mozilla's part, since it was essentially a paid-for promotional tie-in with a TV show, and I would probably agree with you. But it did not damage anyone's computer, compromise any data or do anything that could put it on the "Malware" category.
Something similar that noone has complained about are the Android version names which are promotional tie-ins: Kit Kat and Oreo. Mozilla's biggest screw up IMO was failing to disclose properly what was going on.
