Firefox-based: IceDragon 65 is based on the Firefox 65 codebase. It provides detection for Firefox hard-coded plugin installations.[3]
SiteInspector: Comodo's SiteInspector malware detection system is integrated into IceDragon. SiteInspector's link scanning feature allows one to check whether a web page is malicious before they visit that page.[4][5]
SecureDNS service: IceDragon offers Comodo's Secure DNS Service to users as an alternative to using their Internet Service Provider. This is intended to produce faster page loads and safer browsing because SecureDNS references a real-time block list (RBL) of malicious websites.[4][5]
