I’m using chrome as my browser and cannot open one specific website. It works using Firefox

I think I can explain what is happening. If you are unable to access certain web sites and possibly getting a message that your browser must be updated, this is not an unusual situation. The reason is that web site engineers write their software to work with various browsers based on standardized specifications if they are to be compliant. Some sites are not yet compliant. Also, some older browsers may not be fully compliant. You can try upgrading Chrome or you can just use another browser that does work such as Firefox. Finally, even if you are able to upgrade Chrome, there is no guarantee that it will be compatible with every web site. This is why many of us have more than one browser installed.
