Firefox-based: IceDragon 38 is based on Firefox 38.0.4. It provides detection for Firefox hard-coded plugin installations.
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 actually visit that page.
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 harmful websites.
Social media integration: IceDragon provides a button that allows one to instantly share a web page with their Facebook, Twitter or LinkedIn friends.
Portable: IceDragon provides a portable option during installation. This feature is absent with version 38, but anticipated to be reinstated with version 40.
