You could try changing the User Agent String to something more modernand see if the website works.In firefox you can change it on a site by site basis using|general.useragent.override| but I have lost the computer where I set itup so can't specify exactly.
There’s also the "User-Agent Switcher and Manager" extension, which allows you to spoof the header per-site.
