What is the current status on css 3 and using prefix for rounded corners?

I used to do -webkit-border-radius and -moz-border-radius but now that there is ie9 I was wondering which prefix I should use. So after some googling I found this:

When we added border-radius, we decided not to use –ms as the specification was a Candidate Recommendation at the time. The full module is again a Working Draft to resolve box-shadow issues but border-radius is still at Candidate Recommendation stability. Other browsers either already support the unprefixed version or will in an upcoming release.

So I guess I should use:

-moz-border-radius
-webkit-border-radius
border-radius

It also seems that chrome supports a non-prefixed border-radius but Firefox doesn't so I was wondering if I should only 开发者_StackOverflow社区use:

-moz-border-radius
border-radius

Your best bet is using the example below because altough newer browers dont require the prefix, older browsers that did require the prefix wont work without it

-moz-border-radius
-webkit-border-radius
border-radius
