Foxtrick Beta

Due to lack of developer resources, the only builds that work reliably and see constant progress are beta builds. They contain the latest features and the latest bugs: Download Foxtrick Beta.

Mobile browsers

  • Definitely NOT in the Apple iOS Ecosystem. Addons do not work with Safari mobile and every other browser is forced by Apple to use the same engine, yes, even Firefox. I call this crime against the web™.
  • Kiwi: Untested and not officially supported but might work. Other chromium browser MAY follow in the future: Edge, Chrome, Opera, etc
  • Firefox: The regular builds work with Firefox version <= 68. The new Firefox Preview (version 75+) has locked down addon support for 'recommended addons' only, and Foxtrick is not one of them.
  • Safari/Chrome/Opera: does not work.

Install instructions:

For most browsers, you just need to click one the links above. If that doesn't work, download the file and drag'n'drop it into the browser. For local Google Chrome/Opera builds you need to drag the crx file onto the extensions tab (options->tools->extensions
