EPUB in Firefox OS
I had to thanks Bruno Vilar that lend me the device used for the review.
I have done a review of the EPUB apps for Firefox OS and it support to MathML:
For the review I used the Alcatel One Touch Fire.
It was running the Firefox OS 184.108.40.206-prerelease (based on Gecko 18.1) and the 02002 version of the firmware.
