math equations in Wikipedia cannot be displayed

Binary package hint: firefox-3.5

When browsing the wikipedia.org, math equations cannot be displayed.
I am not sure whether it's firefox's problem or wikipedia's problem, but this is important.

for example, you can try this url:
http://en.wikipedia.org/wiki/Linear_programming

Could you please attach a screenshot of the problem you are having? I can see the math equations without a problem when visiting the link you provided.
