SVG and FF on Solaris

Has anyone manage to get FF to open SVG documents on Solaris.
When selecting a svg document, the browser don't start rendering
the file. But it only ask what to do with the file (save to disk).
There is plenty of nice examples on croczilla that's opens inside
the browser on Linux and Windows but not on Solaris. I'm not sure
if this might be some problems with mime types (since I assume
that's what should trigger FF to render an svg)
