I have downloaded MinimoCE012 and it works.
By opening about:config
svg.enabled defaults to false. I changed it to true
but it does not seem to work.
I get the following error:
=============================
\Temp\4ql3y023.svg could not be saved, becaus ethe source file could not be read.
Try again later, or contact the server administrator
==============
A html file work via the same network connection correct.
Using ethereal I have seen the sr.svg file beeing transfered properly.
