Please let me clarify my solution from yesterday. The addition of the blocking file wont speed things up on those loaders that hit 1% then stop. You will need patience there, with xnxx (its the only one that people mentioned by name for me to test - don't judge me ), it can take 1 min or so of it sitting on 1% - then the player starts and it works fine.

I cant say why this is except there must be something waiting to be loaded in the background that is now a blocking process in the browser.
