Off By One Browser is an independent web browser that runs completely self-contained and does not require any other browser, that means it does not use the IE browsing engine.
It can even run directly from a floppy, CD, ZIP etc. without installation. OffByOne does not support Java or Plugins like Flash - which may limit it for everyday use, but offers the advantage of popup windows free browsing and eliminates the vulnerability to malicious code.
In addition, the browser allows you to surf the web without leaving any tracks, since the page cache and image cache are not stored to disk, but to memory and are erased at the end of the session. OffByOne implements full HTML 3.2 support plus many HTML 4.0 extensions, including Frames as well as SSL. Additional features include cookie management, support for IE favorites, offline file saving, image zoom and more. A nice compact browser that may not be a good choice for an IE replacement, but great if you need a browser that fits on a floppy, or to be included in a CD distribution etc.
