If the nature of this problem didn't also break turnkey distributions like Tor Browser (this kills Noscript, which means your identity can be leaked), I'd agree with you. There's only so much defending you can do against a failure like this (running Tor Browser is already pretty uncommon) and the blame for it has to be laid squarely at the feet of Mozilla for the way they chose to centralize their plugin architecture. This is one of those low likelihood/high impact events that tend to catch everyone by surprise.. if you spend all your time as a user thinking about these failure modes (you don't.. nobody does), you'd be unable to get much else done. I'd wager the fact that the browser would suddenly gimp itself is not something the average user (even the average Tor Browser user) thinks about or plans for.
