Describe the bug
Predirect doesn't support custom instances URL that contain HTTP basic login credentials, eg: https://username:password@domain.ext/
Even if we respect the format (no trailing slash + no https://) so username:password@domain.ext is used, it wont work.
The extension wont show that it doesn't work, and will just ignore it and open the original link
To Reproduce
Use a custom instance URL that contain HTTP basic login credentials
