I’ve been using FF for over 15 years at this point and I have never, not even once, ran into any issues with any site that I went to. Now, is the website you are talking about shareable by you? I don’t want it if it’s a bank or something that could some how be linked to you. I just really really want to see a website that doesn’t work on FF. I’m not trying to come off as a dick or anything, I am genuinely interested to see what it looks like and how it behaves.
