How can I programmatically accept an SSL certificate that is part of a certificate chain issue?

When dealing with certificate chain issues, you can often resolve them by trusting the root certificate or intermediate certificates. While directly accepting a specific certificate in a chain programmatically within Selenium is complex and not a standard feature, the common workaround is to use the `--ignore-certificate-errors` (Chrome) or `browser.ssl_error_behavior` (Firefox) flags to bypass the validation, or to import the necessary certificates into the browser's trust store.
