Me too, on any browser. This is probably a website issue, not a Firefox issue. It’s been reported on their hotline page, which is currently unavailable too (see [https://webcache.googleusercontent.com/search?q=cache:WsYM3PcB_LUJ:https://food52.com/hotline+&cd=1&hl=en-us&ct=clnk&gl=en-us&client=firefox-b here]). I’d suggest to wait a few days and retry. /Edit The website currently displays a warning: <blockquote> We're sorry you’re not able to access the site at this time, but this is a temporary measure to ensure we can best protect your data under new privacy regulations. We value your support; thanks for your patience and we can't wait to have you back! </blockquote>
