Mozilla Firefox will soon include a revised Referrer Policy to tighten up queries and better protect user information. From a report: Firefox 87, due to ship on March 23, will cut back on path and query string information from referrer headers 'to prevent sites from accidentally leaking sensitive user data.' In a blog post on Monday, developer.

Firefox was created by Dave Hyatt and Blake Ross as an experimental branch of the Mozilla browser, first released as Firefox 1.0 on November 9, 2004. Starting with version 5.0, a rapid release cycle was put into effect, resulting in a new major version release every six weeks. Mozilla Firefox® is a fast, full-featured web browser that's easy to use. It has lots of great features including popup-blocking, tabbed-browsing, integrated search, improved privacy features, automatic updating and more.

App Notes

The beta release will install alongside a standard Firefox Portable install in a FirefoxPortableTest directory. Note that PortableApps.com will release one version for each major version (example: 78b1 but not 78b2). For updates within each major release, use the internal updater. From Mozilla: 'This is pre-release software: you may encounter compatibility problems with some websites and add-ons.'
