Warns you when a domain you've accessed contains www as part of the domain instead of the subdomain, preventing phishing.
Attackers have been registering popular domain names that start with www (for example, wwwgoogle.com instead of www.google.com). This is difficult to catch, making it valuable for phishing attempts. This extension blocks requests to these sites, and offers the link with the domain fixed. This extension collects no data and transmits no data.
