What is New in Firefox 5.0?

We downloaded Firefox 5.0 last week.   On first look is quite nearly exactly the same as the previous version.  The

beauty and advancement come out in 5.0’s performance. The first new feature that we noticed, is that the screens can be stretched from any angle, and in any direction, as opposed to the window only being able to be dragged down to the right.  5.0 is faster, it is sleeker and it has a ton of new features.  These include:

  • Added support for CSS animations
  • The Do-Not-Track header preference has been moved to increase discoverability
  • Tuned HTTP idle connection logic for increased performance
  • Improved canvas, JavaScript, memory, and networking performance
  • Improved standards support for HTML5, XHR, MathML, SMIL, and canvas
  • Improved spell checking for some locales
  • Improved desktop environment integration for Linux users
  • WebGL content can no longer load cross-domain textures
  • Background tabs have setTimeout and setInterval clamped to 1000ms to improve performance
  • Fixed several stability issues
  • Fixed several security issues

Essentially, Firefox 5.0 was developed for the release of Max OS X Lion, due to be released in July.  We are currently previewing the 4th Developer’s release of Lion, and boy is it something, Firefox 5.0 makes it just that much better, to work with and play with.  Here are a couple of other reasons why you definitely want to install 5.0:

1. Added support for CSS animations.

Extra support for CSS animations makes it possible to animate transitions from one CSS style configuration to another. The advantage to this is it’s simpler than traditional script-driven animation techniques. You don’t have to know the JavaScript coding language. This rendering engine uses frame skipping and other techniques to keep animation support as smooth as possible. This is definitely a plus for newer Web page developers who want to run unique CSS animations and are just getting started.

2. The latest version is more stable.

Through strenuous testing, I found this release to be much more stable than previous versions–as one would expect. I tested out visiting various sites that would sometimes crash in previous versions. Also, I am one who usually has multiple tabs open at the same time. In my experience, this almost inevitably ended up in a crash of Firefox at some point during the day, especially with multiple tabs open and trying to navigate through complex sites quickly.
