Comodo IceDragon

Comodo IceDragon is a simple-to-use multi-tabbed web browser that focuses on some security features. Plus, it integrates Facebook for easy access.
This tool can also be installed as a portable product. This way, the Windows registry does not receive new entries and no leftover items can be found after program removal.
Plus, you can store Comodo IceDragon on a USB flash drive and always have it with you when you're on the go.
During the installation procedure, you can import history, favorites, cookies and passwords from the default browser, as well as choose the COMODO SecureDNS servers for security reasons.
The interface of the tool is clean and intuitive, familiar to the one of Firefox. Comodo IceDragon lets you manage addons and plugins, change the default theme, as well as access web developer tools (e.g. web console, debugger, style editor, error console).
Furthermore, you can start a private web browsing session, switch to full screen mode, set bookmarks, customize the toolbar and change the interface language. From the 'Options' area you can block popup windows and disable JavaScript, change fonts and colors, as well as enable a master password, among others.
The web browser has a good navigation speed and uses a high amount of system resources. We have not encountered any issues throughout our tests; Comodo IceDragon did not freeze, crash or pop up error dialogs.
