I downloaded Firefox 3.5 the day it came out. Won’t go into a lengthy review but there are some of my first thoughts about it:

• A little snappier and faster
• A few minor design/UI changes
• And finally private browsing is here

Here are the notable changes via the release notes.

Available in more than 70 languages.

Support for the HTML5 <video> and <audio> elements including native support for Ogg Theora encoded video and Vorbis encoded audio.

Improved tools for controlling your private data, including a Private Browsing Mode.

Better web application performance using the new TraceMonkey JavaScript engine.

The ability to share your location with websites using Location Aware Browsing.

Support for native JSON, and web worker threads.

Improvements to the Gecko layout engine, including speculative parsing for faster content rendering.

Support for new web technologies such as: downloadable fonts, CSS media queries, new transformations and properties, JavaScript query selectors, HTML5 local storage and offline application storage, <canvas> text, ICC profiles, and SVG transforms.

If you bothered to read all the *notable* features, I’ll give you a thumbs up (Y). Anyway, make sure you do get Firefox 3.5. It’s always a good idea to get the latest version of any software.
