While viewing a video in full screen using Firefox, I have this annoying “flash” in the lower left corner every ten seconds which simply says “challenges.cloudfare.com”.
A major distraction/annoyance.
I figured out that I could disable javascript after the video starts to keep this from happening, but that isn’t a solution.
How can I simply filter this out without breaking websites? Is this a Firefox issue? A Cloudflare issue? An issue with the video provider? Thank you!
