Note that this is NOT a general release of RC1 for the public! Do NOT apply this update unless you consider yourself a tester of beta software. The Release Notes page linked below says:
Firefox 3.5 (Release Candidate) is the seventh development milestone of Firefox 3.5, the next version of the Firefox web browser. While this release is considered to be stable, it is intended for developers and members of our testing community to use for early evaluation and feedback. Users of the latest released version of Firefox should not expect all of their add-ons to work properly with this milestone.
Firefox 3.5 (Release Candidate) Release Notes [NOTE: All downloads referenced in this page now link to Final Build instead of the previously linked-to 3.5b4 beta.]

* This beta is now available in more than 70 languages - get your local version.
* Improved tools for controlling your private data, including a Private Browsing Mode.
* Better performance and stability with the new TraceMonkey JavaScript engine.
* The ability to provide Location Aware Browsing using web standards for geolocation.
* 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: HTML5 <video> and <audio> elements, downloadable fonts and other new CSS properties, JavaScript query selectors, HTML5 offline data storage for applications, and SVG transforms.
Here is a direct FTP link for downloading the Firefox 3.5 RC1 version: 3.5rc1.
[NOTE: The Final Build has superseded all RC builds.]
A post obtained via Google Groups is partly quoted below:
On June 19th, we hope to release (on our website, as a full download)
a release candidate. Right now that would be the rc2build2 version, as
it's the latest thing we have. So, in other words:
June 16th: Firefox 3.5 beta users get updated to an early release
candidate (rc1build2)
June 19th: Firefox 3.5 beta users get updated to the official release
candidate, which is also put up for direct download (right now this
would be rc2build2, but that may yet change!)
end of June: target ship date for Firefox 3.5
Stay tuned for details.
[Edited to reflect release of Final Build and change in the pages linked to. 6/19, 6/27, and 6/30/2009.]
