Bypass CORS checks

The CORS Everywhere extension does no longer work as of September 2023.

Here is a workaround (method 1), which does not always seem to work however:

1. Go to about:config
2. Search for security.fileuri.strict_origin_policy and set it to false.

Apparently this does not work, it is only for local files.
