-prefix-free lets you use only unprefixed CSS properties everywhere. It works behind the scenes, adding the current browser’s prefix to any CSS code, only when it’s needed.
“[-prefix-free is] fantastic, top-notch work! Thank you for creating and sharing it.”
— Eric Meyer

Properties as well in Firefox < 3.6.Check this page’s stylesheet ;-)
You can also visit the Test Drive page, type in any code you want and check out how it would get prefixed for the current browser.
Just include prefixfree.js anywhere in your page. It is recommended to put it right after the stylesheets, to minimize FOUC
That’s it, you’re done!
The target browser support is IE9+, Opera 10+, Firefox 3.5+, Safari 4+ and Chrome on desktop and Mobile Safari, Android browser, Chrome and Opera Mobile on mobile.
If it doesn’t work in any of those, it’s a bug so please report it. Just before you do, please make sure that it’s not because the browser doesn’t support a CSS3 feature at all, even with a prefix.
In older browsers like IE8, nothing will break, just properties won’t get prefixed. Which wouldn’t be useful anyway as IE8 doesn’t support much CSS3 ;)
Test the prefixing that -prefix-free would do for this browser, by writing some CSS below:
The transition from version 2.x to 3.0 represents a significant technical leap. While previous versions were functional, they often relied on older architectures and sometimes cumbersome driver implementations. The 3.0 Beta promised—and has largely delivered—a modernized experience. Built to run natively on modern Windows operating systems without the need for complex driver signing workarounds, the beta version introduced a more streamlined user interface and, crucially, support for the XUSB protocol. This allowed users to connect their console drives via USB with greater stability, moving away from the fragile SATA-to-USB bridge solutions that plagued earlier workflows.
In the realm of file system analysis, having the right tools at your disposal can make all the difference between a successful investigation and a prolonged, arduous process. One such tool that has gained significant attention in recent times is FatXplorer 3.0 Beta Verified, a robust and feature-rich file system analysis tool designed to simplify the process of examining and understanding complex file systems.
FATXplorer 3.0 is a popular Xbox storage exploration tool currently in an extended beta phase. As of early 2026, version is one of the most recent stable releases, with the beta program continuing to introduce new features like 16 TB drive support and SSD compatibility for unmodded consoles [8, 9, 22]. Key Features of the 3.0 Beta
The "verified" status isn't just marketing—it's a promise. It promises that your precious game saves, your meticulously curated ROM collections, and your childhood gaming history are safe when you plug that old hard drive into a modern PC.
All features labeled "write support for secure partitions," "Series X|S NVMe," and "direct sector editing" are 100% verified working in the latest 3.0 Beta builds.
Crucial for the original Xbox modding scene, it supports large hard drives (up to 16 TB), allowing users to manage massive game libraries easily. Formatting Tools:
A critical distinction for new users is that FatXplorer 3.0 is no longer free.
