Using the uMatrix browser plugin I block 3rd party JS by default. It's not that common a thing to do but maybe displaying an error message rather than reloading the page on script load failures?
Oh I see... well, I had to add locks because some of my games got stolen and monetized in the past. So this version of the locks is still in Beta, but I just came up with a new logic for it. Removing the re-load btw... Thanks for your help!
