Bet 365 website unavailable to me using Firefox

[Snoopdog]

I cannot access B365 website when using Firefox. I'm getting a screen from Cloudflare security: "Sorry you are blocked!" The website is OK using MIcrosoft Edge. I had this before about a week or so ago. It went away, now it's back. Google seems to suggest I'm not alone. A live chat with them went as below. Any ideas?

(Chat deleted due to formatting issue - 365 basically said they couldn't identify the issue and suggested using other browsers - harry_rag)
