MathML works -- with FFBeta 23.0 on ICS HTC EVO 3D Noté 5 sur 5 étoiles

I'm using FFBeta 23.0 on an HTC EVO 3D with Android ICS 4.0.3.

Before installing MATHML add-on:

The quick vertical-line test page,
https://developer.mozilla.org/en-US/docs/Mozilla_MathML_Project/Fonts/Test
was faulty, with multiple and blurry vertical lines.
The "Mozilla MathML torture test" page
https://developer.mozilla.org/en-US/docs/Mozilla_MathML_Project/MathML_Torture_Test
didn't render vertical ellipsis ("…") or horizontal brace ("{") at all, but the rest of the page was acceptable.

After install MathML add-on:
The simple lines test is perfect.
The "Mozilla MathML torture test" page renders everything, including vertical ellipsis and horizontal brace, reasonably well with the "default font". Everything is even better rendering with the additional fonts, Asana, MathJax, and STIX. The MathJax font seems the closest to the supplied TeX examples.

I recommend installing MathML is you need to browse websites with mathematical formulae.

Glad to hear this add-on was useful. You might be willing to star (follow & vote) this Android bug:

It seems that it has been assigned to someone recently, so hopefully it will be fixed soon.
