[question] Which blocks the request first: uBo or uMatrix? #882

I am willing to block certain behind-the-scene requests. Tested scenario:

  1. Set rule to block youtube.com in behind-the-scene (read cases below)
  2. Open youtube.com
  3. Watch loggers of uBO and uMatrix

Cases: a. If in 1. uBO blocks but uM allows - loggers show the request is blocked in uBO, but not in uMatrix b. If in 1. uMatrix blocks but uBO allows - loggers shows that uMatrix blocks but uBO allows c. If both uBO and uMatrix are set to block - both loggers show that the request is blocked, i.e. the request still reaches the other extension

So what is the proper (earliest) way to block a request? And what is the priority? I.e. if a request is blocked by one extension - is it allowed after that by the other one (i.e. does it still "pass")?
