I think it is probably caused by flash plugin, try other sites with flash files and you likely get it crashed again. It is not a mozilla problem, but comes from the plugin itself. u can either try flash plugin with lower version or simply delete it. Details refer to technical notes from web master of this site(can not remember which one is that :neutral: ).
I reckon the problem comes when u install it. I installed it when 2 of its required chinese fonts are missing, so the plugin crashed whenever it loads these fonts. I don't have time to check it out, so make sure your system meets all the requirement of the installation. Anyway, it also may not be the cause, as I have no korean fonts on windows 98, but ie can still deal it correctly.emm, get confused.
