Firefox 42 will not allow unsigned extensions

What is the point of this? Shouldn't users be allowed to make their own decisions no matter how stupid or dangerous?

The issue is that most users don't understand software on a deep level, and just click "yes" on dialog boxes, etc.

It does make sense to keep the defaults where it prevents most users from harm.

Approximately 5% of users are infected with adware. This is one way to combat it. Google has already taken this approach.
