Hate adding the same CSS over and over again, with different vendor-specific prefixes each time? PrefixFree is a page or folder Action which allows you to apply the prefixfree.js script to your page, dramatically simplifying any new or experimental CSS you may add to your site.

As new CSS techniques and attributes are created by browser developers, they often provide them initially as a vendor-prefixed experiment for early adopters. As they are ratified by the W3C, many browser versions may still be extant that have no idea how to deal with them without their prefixes. Usually, this means you have to write the same thing three or four different times, with different prefixes. PrefixFree (as it says on the tin) allows you to write the W3C syntax alone, and synthesizes the rest on page load, depending on the browser in use.


If you are using Google Web Fonts in the same page as this script, you must add a prefetch declaration to the rel attribute of that stylesheet link.

<link rel="stylesheet prefetch" href=" … " media="screen" />
