Why should Mozilla act? This only affects nightlies and beta, as the article stated. If you use one of those, you should expect things to occasionally not work.
When I asked my 11-year-old brother what browser he used (since I saw chrome and firefox on the desktop), he informed me that he used "Firefox Nightly" (which I hadn't noticed, but was also present), because "it's a little better". He had no idea what it was. I don't know how he found it in the first place.
