How to stop CORB from blocking requests to data resources that respond with CORS headers?

Question

I am developing a Chrome extension which makes requests from certain websites to an API I control. Until Chrome 73, the extension worked correctly. After upgrading to Chrome

Answer 1

Temporary solution: disable CORB with run command browser --disable-features=CrossSiteDocumentBlockingAlways,CrossSiteDocumentBlockingIfIsolating

Example run command on Linux.

For Chrome:

chrome %U --disable-features=CrossSiteDocumentBlockingAlways,CrossSiteDocumentBlockingIfIsolating

For Chromium:

chromium-browser %U --disable-features=CrossSiteDocumentBlockingAlways,CrossSiteDocumentBlockingIfIsolating
