text: Different browsers render a little differently.  Some html is not recognized by all browsers.  It is very common for sites to not render correctly in Firefox because it is less tolerant to errors in the html.  Most likely, the code was not written well or not written to accommodate browsers other than IE that don't recognize certain pieces of html code that IE does.  I can't even access the sites I have to use in my job from Firefox.  They don't play well together.\n\nNot all webpages should show up poorly, though.  Something big like Yahoo or Google should be well written to work well with Firefox.
