  "notes":"Support in Chrome may <a href=\"http://blog.chromium.org/2011/01/html-video-codec-support-in-chrome.html\">be dropped</a> in some upcoming version.

Firefox <a href=\"http://blog.lizardwrangler.com/2012/03/18/video-user-experience-and-our-mission/\">will include support</a> on some platforms in upcoming versions. Firefox supports H.264 on Windows 7 and later since version 21. Partial support for Firefox refers to the lack of support in Linux platform, and for Android Firefox it refers to the inability of hardware acceleration.",
