@Printdevil When you connect to their website, it downloads some JavaScript and says "verifying the device", which I take to be a lying, weasel way of saying, "fingerprinting your web browser".
I tried disabling that JS but then the site does not load.
FireFox has some fingerprinting protection built-in but it's clearly not enough in this case.
I need to do some research. But it shouldn't be up to tech-savvy users to figure out a workaround, it should just be illegal.
