Conflict with Tempermonkey in modifying "Content-Security-Policy" #778

Closed VictorSu000 closed 7 years ago

VictorSu000 commented 7 years ago

uMatrix and Tempermonkey seem to work well so far, but an warning message pops up, which says "During network requests Tempermonkey can't modify "Content-Security-Policy" in response headers, because this modification conflicts with another extension uMatrix."

Browser limitation, only one extension can modify a HTTP header. You will have to pick which one you want to modify the header. Take note that uMatrix never make a CSP header less strict, it only makes them same or stricter. I believe Tampermonkey can potentially make the CSP header less strict. You will have to seek information with Tampermonkey authors.

@VictorSu000 Open settings and set the settings mode to Advanced mode, scroll down to the end and in Security category somewhere, there's a CSP setting, disable it.

If you don't want to do that, then use ViolentMonkey instead of TamperMonkey.
