Support for Chrome 73 new CORS security

[CrazyCoder]

Many extension features don't work in Chrome Beta 73.0.3683.27 and later. It will stop working on 12 March 2019 in Chrome 73 release as well.

The error in the Console may look like:

Cross-Origin Read Blocking (CORB) blocked cross-origin response https://... with MIME type application/json. 

See https://www.chromium.org/Home/chromium-security/extension-content-script-fetches .

Workaround: open chrome://flags, set Enable network service flag to Disabled
