That site won't load in my Firefox.
nitter.net has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.
Maybe it wont work because your browser doesn't allow legacy http connections?
put this in the address bar: about:preferences#privacy
hit enter
scroll way down the page and look for
HTTPS-Only Modeyou can disable it (probably not a great idea) or add an exception for nitter.net
If that's not it, it might be your operating system or perhaps your anti-virus/malware software?
Nice thinking xhomerx10, but I had already HTTPS-Only Mode disabled. The wording of Firefox's error message makes me think it is Nitter that insists on https.
