Description (please include examples/screenshots where applicable)

When clicking on a link that looks like https://tracking-domain.com/?url=example.com, with uBO installed and a filter like ||tracking-domain.com^ (AKA block everything from that domain), Skip Redirect will report a successful redirect to example.com, but the browser will navigate to the uBO page that says, "uBlock Origin has prevented the following page from loading:…" and stay there.

For example, ensure that "Peter Lowe’s Ad and tracking server list" is enabled in uBO, then go to isthereanydeal.com, and click the link to view a game on GreenManGaming.

This looks like a limitation in the way that the browser handles multiple extensions trying to modify the same network request.
