That’s the underlying problem here: web sites are constantly getting suspicious traffic and if you do something like using Tor or a “free” VPN, the owners of those sites are probably going to ask companies like Cloudflare to validate or block you rather than try to tell whether you’re a bot.
Anyone concerned with privacy really needs to be focused on that problem because most site owners care more about not going broke than supporting browsers or privacy tools which few of their customers use. It’s destroying the open web.
I have seen it myself, from my own system. Firefox, almost impossible to use the web due to non-stop bot checks by CF. For the same session, same site(s), I give up and use Chrome, with all the same browser extensions, and I sail right in. Multiple times.
Suspicious traffic is using Firefox, because Chrome browsers are 90%+ of the traffic. And the rich mac users have a special mechanism for bypassing them as your article outlines.
Using Firefox is the internet equivalent of DWB.
I don't know the cause of what you're seeing, but it's not simply Firefox.
This is very much not my experience. I don't know if you use a VPN or have a ton of extensions but if I was hitting that so hard I'd consider trying a clean profile with no extensions and adding things back in to see if you can find the trigger condition.
I see exactly the same amount of security checks, as far as I can tell.
