Safari and .aspx files

[Jackster1]

Hi. I suspect this is an issue with the programmers at my bank, but I'm fairly illiterate, so I thought I'd ask this question. My credit card is through my bank. Using Safari, I am able to download my bank statements using Safari with no problem. But, when I try to access my credit card statements (which are in .aspx format), no statements load at all, thus I am unable even to select a statement to download. I can open my credit card statements with no problem using either Chrome or Firefox (both of which I don't care for), but it's a pain to have to use a different browser just to access my credit card statements. I am resisting switching to a different browser - Safari and I think alike. Is there any way I can get Safari to work in this case? Thanks in advance.
