There's two reviews, one saying it's perfectly safe, and the other saying they constantly send spam to his 2 email accounts - who to trust? I don't know, but the first customer did explain what the purpose of it was, and as he said: "you need to be a customer/user to have access to this in any case." That to me is enough to leave it "blocked" in µMatrix (well, except for CSS & images, though I could block them too...) - NOT because there's anything bad about the site, but because it's totally useless for me, and why would I bother to take the extra kilometer (Metric system is universal bi7c3s!) to allow a site I don't need. Note: That I said "not because there's anything bad" doesn't mean there isn't - I wouldn't know. It's just something I don't know about. Also when I said "blocked", in quotes, I don't mean actually black-listed (or "red-listed"), I just mean it's default settings - that means everything from the domain is blocked, except types of stuff that's allowed by default (which is css & images in µMatrix). "red listing" blocks them as well, while "green" allows everything, except frames, which you'll have to allow separately if necessary. Don't let this scare you - µMatrix is actually really simple, and a lot better than NoScript - µMatrix combined with µBlock Origin (DON'T install the "µBlock" without the "Origin" in the name, it's scam) are the two most important extension I always install on new Firefox - not the only ones, but top 2. But I'm beginning to ramble totally unrelated stuff... Actually been doing that for most of end-half already, sorry.
