Bring back the working now.gg "proxy block" fix

[nvd123YT]

Wanted to add to my fork and for general use
The file it was located in in the repository (frame.js) no longer exists

The fix is iffy and was very unreliable. There is a github issue you can follow: #552

why are you trying to bring it back when it is unreliable and likely does not work?
