Fifth – web browser

Last Updated on December 24, 2022

Fifth is a Linux-only open source browser that offers the best features from Opera, as well as a few unique features that are aimed for Linux power users. It’s based on a custom WebKit port to FLTK.

Fifth gives you the possibility to spoof as many items as possible used to detect and profile you. Each version will be released with the most common defaults according to research such as the EFF panopticlick.

Fifth is designed only for browsing. Fifth is not for playing multimedia or games; it does not have native video support.

Features include:

  • Fully customizable per-site.
  • Full control for the user; override settings, such as CSS, JS, and cookies.
  • Very low RAM usage; lean, no Flash or WebGL.
  • SSL certificates handled in a SSH-like manner.
  • Focus on performance and memory management. All features are written in C/C++.
  • Privacy – with no information leaked. Anonymous browsing improvements.
  • Bookmarks.
  • Speed dial.
  • Screen capture.
  • Spoof accept and language header, timezone, and user-agent; by default, Fifth claims to be Firefox running under Windows.
  • Supports two types of content blocking: blacklisting and whitelisting.
