some additions:
Lynx is a fully-featured World Wide Web (WWW) text-browser for users on Unix, VMS, and other platforms running cursor-addressable, character-cell terminals or emulators. That includes vt100 terminals, other character-cell displays, and vt100 emulators such as Kermit or Procomm running on PCs or Macs.
Konqueror is an Open Source web browser with HTML4.0 compliance, supporting Java applets, JavaScript, CSS1 and (partially) CSS2, as well as Netscape plugins (for example, Flash or RealVideo plugins). But it's a little unstable (IMHO).
Firefox is a new line of mozilla's browser. More faster, more stable! (this is my choose )
