SMIL
From MozillaWiki
This section of the wiki is for discussing the implementation of SMIL Animation in Mozilla. Currently we're only implementing SMIL Animation for SVG.
SMIL Animation support is now built into trunk builds by default (it's included in the nightlies), and it's enabled by default. (To turn it off prior to Firefox 21, you can toggle the svg.smil.enabled pref to false. From Firefox 21 SMIL will always be enabled)
The SMIL Animation implementation is built on the work done by Brian Birtles. You can see a detailed report of this work at: http://brian.sol1.net/svg/report/report.pdf.
