Mozilla and MathML

2 Nov 2005

      I'm having problems with Mozilla viewing MathML.  The problem I am having with 
the build from SuSE 10 is different from what happens with the mozilla 1.7.12 
from mozilla.org.  If someone would verify this, I would appreciate it.  I 
want to report one, or perhaps two bugs.  With the Mozilla that ships with 
SuSE 10, I do not see the ∄ in the xhtml below.  With the build 
from mozilla.org, there are incorrect and, downright weird fonts shown. 

If you get an error saying you need to install special fonts, you can ignore 
that in this case.  If you want the fonts, follow the links in the error 
message, and get the _4.1_ fonts. One thing I've noticed with the Mozilla 
from SuSE is that it seems to have MathML fonts built in.  I don't get the 
error telling me to get the Math fonts that I get from the mozilla.org build.
