@Fox Good link there. Unfortunately, that code, executed right before a Page Load, doesn't mute Ajax-called elements like audio players or video ads. Too bad they didn't allow for a setting within the Browser or within a Chromium call itself. Thanks for the tip on Google Translate - works great!
use http client if you want speed . if browser is only solution then you need to disable everything you can ex . images, scripts and other blockable objects .
