Is this incorrect? I also tried with the global CDN examples at https://raw.githubusercontent.com/migueldemoura/ublock-umatrix-rulesets/master/uMatrix/recipes and got the same result.

Your environment

• uMatrix version: 1.3.8
• Browser Name and version: Chromium 66.0.3359.139 64-bit
• Operating System and version: buntu 18.04

[uBlock-user]

I can reproduce in Chromium 68 and in the latest dev build.

Might I add that the built-in rulesets work just fine.

There are things to fix on my side. However, even after the fixes your recipes file is still not parseable by uMatrix, because it's missing the mandatory top line:

! uMatrix: Ruleset recipes 1.0

This is a requirement for uMatrix to parse the file as a ruleset recipes file. uMatrix will still import files without that mandatory line because it can only know the file is invalid after importing and loading it.

Thanks @gorhill!
