IT's a Pain
Cloudfare is a pain in the proverbial. It has prevented access when using Firefox (and even Chrome etc) to websites that access have been paid for begining 3 months ago. Which is worse when the only way to contact the vendor is via the website, e.g. Crunchyroll.
It has also prevented me from getting my takeaway via Just Eat, grumble, grumble - of course going direct is doable so I do not need a takeaway aggregator - but still it is not convenient and prevents actual business happening
