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:
Update in 24/12/2013 thanks to FrƩdƩric Wang: one of the extensions of Firefox to read EPUB is LUCIFOX (it's GPLv3) but it didn't have a version for Firefox OS. One of the Javascript libraries to read EPUB is Epub.js (it's BSD) but it require node.js. And any of this readers support interactive EPUB.

This is a review of the Firefox OS EPUB readers app MathML support. For testing I used A First Course in Linear by Robert A. Beezer from IDPF epub-sample repository.
Current there is two EPUB readers app in Firefox Marketplace: EPUBReader and Ab FB2 reader. The Ab FB2 reader won’t be able to load the file.
When open the file it show the cover.

Moving to the second chapter we find the presence of some MathML elements.

Published on December 18, 2013.
This is a review of the Firefox OS EPUBReader app. I can’t find the license of this app but probably it’s similar to the one of EPUBReader Firefox extension that can be found here (it’s not compatible with GPL). For testing this app I used:
- A Christmas Carol in Prose; Being a Ghost Story of Christmas by Charles Dickens from Project Gutenberg and
- Moby Dick by Herman Melville from IDPF epub-sample repository.
It has a very simple home page with a single button in the top that list the files that can be open.
