[solved] firefox unable to show math symbols?

Im trying to read some math websites but instead of the symbols i only get greek symbols.
Now i tried to find some answer to this but i only found very little and very old stuff that didn't help me.

If you want to check if your Browser displays them properly just go to this site:
http://www.mathe-online.at/einstellungen/einst.html#MH and scroll to the bottom.
The right picture shows the symbols as .gifs and the left picture tries to do the same using math symbols.

Any help would be very appreciated.

**Final Edit: following the instructions provided by the link in Edit2 corrects the problem.**

Edit2: Read this http://silas.psfc.mit.edu/tth/symfontconfig.html before trying the stuff below.

Did you try following the instructions in the provided link? http://hutchinson.belmont.ma.us/tth/Xfonts.html

I haven't tried it yet, so I don't know if it will work. I wanted to ask if you had already done so before I started messing with it. (and, no, I can't see the symbols either) Perhaps there is a required symbol font that must be installed?

Edit: After looking at the script that link provides, it appears that the adobe symbol fonts aren't added to a fonts.alias file anywhere, so the browser can't find them. It also tries to modify the mathml files used by mozilla. I think the script will need to be modified a little to work with firefox, but I'm not positive.

Well, i edited both /usr/share/fonts/100dpi/fonts.alias and 75dpi/fonts.alias and added

See my final edit. You will probably need to manually edit the mathml.css file as suggested by the link. (This one:
http://silas.psfc.mit.edu/tth/symfontconfig.html )

It worked for me using mozilla-firefox-bin-1.5.0.4. For the -bin version of firefox, the mathml.css file is in /opt/firefox/res.

damn, it doesn't work for me, i already runned that script before and my mathml.css is fixed properly.

So, my mathml.css and my font.alias files are both alright, did i forget something else?

Im using firefox-1.5.0.4 from source btw.
