Stop Sval blocking a domain
An allowed domain is never blocked, on any site and at any level.
A list blocks the domain your bank’s site loads its sign-in page from, and you can’t sign in.
- Open Settings › Privacy and protection.
- Under Allowed domains, select Add domain.
- In Domain, type the domain or paste an address.
- Select Add.
Sval never blocks requests to that domain or any address under it.
