Nowadays for almost all websites SSL/TLS (https) is required.
The techniques used for SSL at the time that Windows XP was not retired are no longer used or supported by most websites.
In other words, your Windows XP lacks the ability to communicate with modern websites.
Perhaps that Firefox long term support (ESR) works, but they also state Windows 7 as a minimum
So probably that won't help either.
Quite frankly Windows XP should under no circumstance be used to browse the internet.
The operating system has a large number of vulnerabilities and connecting it to the internet is begging for trouble.
