In the spirit of http://dowebsitesneedtolookexactlythesameineverybrowser.com/
I have stopped including the -moz-border-radius prefix on projects and here is the rationalization:
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
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
