" Actual results: Win7 + Firefox+720P WebM video uses more power than any other combination. Expected results: Provide hardware decode support for WebM.

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:21.0) Gecko/20130120 Firefox/21.0 Build Id: 20130120030952 It works for me on 20.01.2013 Nightly build. I've tested by opening a 720 webM video (on youtube and vimeo) and I see no difference in CPU usage between Firefox and Chrome. I've performed the same steps on the latest Nightly (from 25.01.2013) and the results are identical. Could you please provide some extra information regarding this issue? Do you have any add-on installed?
as said in comment 0 , this is from a test done by Anandtech.com , which i happened to read. Since his comments were so negative towards FF, i decided to file a bug on that. I personally do not have the necessary hardware to test. The power consumption for FF+WebM video is "Win7-HTML5 WebM (720P)". Do you use a Ivy bridge CPU with the integrated HD4000 GPU ?
this is probably solved now by the large A/V changes done.
