It doesn't work for me. When it starts, I get a bunch of errors:

Error fetching https://speed.cloudflare.com/__down?measId=4466372954803167&...: TypeError: i is undefined

Then it pauses itself. When I resume it, it runs for a few seconds (printing more errors) and pauses again.

I am using Firefox 76.0.1 on Fedora 32 x86_64. None of the adblocker addons I'm using are blocking anything.
