text-based web browser
Lynx Portable can run from a cloud folder, external drive, or local folder without installing into Windows. It's even better with the PortableApps.com Platform for easy installs and automatic updates.
Lynx is a text-based web browser with support for HTML4 (no CSS), HTTP 1.1, tables, frames, and more. Full keyboard shortcut support like q to quit and g to go to a URL. Note that this browser can not save cookies between sessions, apparently due to a bug.
