Thank you for your feedback Mohamed.
You're right, I should have say that this work on arabic mathematical
notation started a long time ago thanks to Azzeddine LAZREK and his team
of researchers from Cadi Ayyad University:
The RTL markup was finally standardized in MathML3 in October 2010 and
now going to be included in Firefox :-)
Yes, I was also told that Moroccan people no longer use this notation. I
think in Tunisia, people are still using the RTL notation, at least
until high school. The W3C note I mentioned in my last mail  gives
more details, but folks here certainly know more than me about that subject.
As for your question on Firefox on Android, I don't know if there is an
Aurora version for this platform? Can you tell me which version of
Firefox you are testing?
BTW, there seems to be a problem with STIX fonts on Android, causing
grey rectangles to be displayed on your screenshot:
