Don't allow eval just for OCRAD.js

[siphomateke]

OCRAD.js uses eval to do OCR on ZRA's login captchas. This is blocked in extensions by default to increase security. We've had to allow evals to run just so OCRAD.js runs normally.

A better workaround should be found rather than just allowing all evals to run. Perhaps using a different OCR library or running OCRAd in an iframe.

exactly, @siphomateke did you find any alternatives for this? I tried Tesseract, it is much slower than ocrad.

@hbzhang3 Hey, I haven't worked on this project in over 3 years, so I'm afraid I can't help much. That said, I switched to using a more advanced OCR model than Ocrad.js, which you can see here https://github.com/siphomateke/zra-captcha-solver.
