It had worked for 13, but got disabled in 14.0.1. The other preference, extensions.strictCompatibility can still override all this add-on's work, making it useless in that situation, and you still have to go in to about:config to re-enable your add-ons. So, this add-on is only a partial solution - at least this dev tried and I respect that. Still, a miss is as good as a mile. Why is mozilla so stupid about add-ons? I am not even sure how extensions.strictCompatibility keeps coming back. It's ridiculous.
