Hello support, I am doing some challenges on a website called tryhackme.com . On a challenge the http web server is on port 22. When I try to access that page it tells me that the page is restricted. I access the about:config page and add as a string the following thing network.security.ports.banned.override and as a value 22. When I try to reload the page it tells me the same thing.How can I resolve this issue? Kind Regards, Dan Barbu
