Start dropping some -moz prefixes

In the spirit of http://dowebsitesneedtolookexactlythesameineverybrowser.com/

I have stopped including the -moz-border-radius prefix on projects and here is the rationalization:
According to
https://developer.mozilla.org/en-US/docs/CSS/border-radius
border-radius has been supported since FF4

When checking http://en.wikipedia.org/wiki/Firefox for the release history we can see, that FF3.6 was released nearly 3 years ago, FF4 has been available close to 2 years. So Users who have not upgraded their FF in 3 years falls into the ~1% and under category of browsers on the web
See:
http://gs.statcounter.com/#browser_version-ww-monthly-201207-201209
http://www.w3schools.com/browsers/browsers_firefox.asp

Which is almost equal to supporting IE6.

Now some clients want full cross browser support, and they will have to pay for IE6 compatibility, so why not FF3.6 > compatibility?

I'm just throwing it out there that maybe it's time to start embracing CSS3 without certain -moz vendor prefixes. (webkit will probably be a different ball game)

Like if you agree, comment if you disagree :)

PS: Or drop all prefixes and start using a JS script like

PPS: same goes for box-shadow https://developer.mozilla.org/en-US/docs/CSS/box-shadow but not for box-sizing https://developer.mozilla.org/en-US/docs/CSS/box-sizing so research the common -moz prefixes you want to drop and let them go
