Firefox 1.5 RC3 has become the official release of Firefox 1.5. This heralds the second major browser (after Opera 8) to natively support some form of SVG (Opera 8 supported SVG Tiny 1.1 back in April 2005).

Firefox's implementation of SVG is not exactly SVG 1.1 Full, nor does it fully cover SVG 1.1 Tiny nor SVG 1.1 Basic. Details of the Firefox 1.5 SVG implementation are located here, while details of the SVG implementation in the development version of Firefox (aka "the trunk") are located here (though this will not be released until some time in 2007 as Firefox 3).
