Firefox 4 dah keluar, dah cuba?

Super Speed

With faster start-up times, rapid graphics rendering and improved page load speed, Firefox 4 is full of major performance improvements you’ll notice instantly. From integrating Compartments and more efficiently managing JavaScript objects to supporting ECMAScript5 and building the brand new J├ĄgerMonkey JavaScript engine, we’ve been working hard under the hood to make this the most powerful Firefox ever.

Crash Protection

Firefox provides uninterrupted browsing when there is a crash in the Adobe Flash, Apple QuickTime or Microsoft Silverlight plugins. If one of these commonly-used plugins crashes or freezes, it won't affect the rest of Firefox. Instead, you can simply reload the page to restart the plugin and try again. Learn more about plugins.

Real World Performance

Having a super fast JavaScript engine is definitely important, but since those changes are often measured in milliseconds sometimes what matters even more is the way the browser feels when you’re actually using it. That’s why we’re constantly optimizing Firefox to be great for the way you use the web – things like making new tabs open up more quickly, or having the Awesome Bar provide results even faster. In the end, it’s about getting you where you need to go as quickly and easily as possible.

3D on the Web

WebGL brings 3D graphics to Firefox, opening the door for developers to create vivid games and new kinds of visualizations and experiences for the Web.

Hardware Acceleration

Experience super-fast graphics acceleration of video and Web content with a new layers-based graphics system that takes advantage of Direct2D and Direct3D on Windows and OpenGL on Mac.
