Firefox 16.0.1: Firefox on Mac OS X now has preliminary VoiceOver support turned on

Every time there's a Firefox update, I get full of suspense and uncertainty... it seems they like making changes just for the sake of making them...

This Time they added: "Firefox on Mac OS X now has preliminary VoiceOver support turned on by default"

Anybody that already upgraded to version 16.0.1:

- Is this an issue?
- Is it an annoying feature?
- What does it do?
- How to disable it?

Any other features that are troublesome?

I need to get all this sorted out before I upgrade myself...
