The WURFL database is very popular. So most likely it carries the data that most websites need. Sadly it also carries a lot of other, likely unused data. Like if the browser supports iframes and/or javascript. I've heard that screen size as well as video decoding capabilities (not just ability to decode, but the ability to do so at a good framerate) have been requested for FirefoxOS partners. I've tried to reach out to facebook and a couple of other sites to find out what information that they use. However I didn't get any definitive answers and haven't had the bandwidth to hunt them down for a real answer. Definitely something that would be great if someone wanted to take on. / Jonas _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
