-moz and -webkit?

[ARG01]

Quick question for my theme design colleagues, rivals, etc.

With today's modern browsers, do you find it necessary to still use "-moz and -webkit" when writing custom CSS?

For example:

When creating a border radius in the past I have used code such as;

Code Select Expand

-moz-border-radius: 0 0 6px 6px; -webkit-border-radius: 0 0 6px 6px; border-radius: 0 0 6px 6px;

but lately I have noticed more and more designers sticking with just;

Code Select Expand

border-radius: 0 0 6px 6px;

I currently don't have Opera but it seems to function just fine in the latest Firefox, IE and Chrome. Should we still be concerned with older versions of IE when it comes to CSS code? Or should we just move on with modern times?

Since this is more of a general inquiry than a need for support, feel free to move to Chit Chat if need be.

Some old versions tried to use their own prefixes but that fail you are pretty much support 90% of all browsers with just using general term like border-radius / background-image: linear-gradient etc... Those prefixes dropped with FF29+/Chrome 10+
