Want to try Firefox features before they reach the public release? Mozilla Firefox Beta brings upcoming browser changes into a pre-release build, so you can browse with them and send Mozilla feedback about problems.
Try upcoming Firefox features
Firefox Beta is intended for testing features that are close to release. It offers a preview in a browser build designed to be more stable than an early development platform, while still subject to changes and bugs. Normal browsing tasks—opening pages in tabs, bookmarking sites, and using Firefox add-ons—fit into the same browser workflow.
Using Beta gives Mozilla feedback from everyday browsing before features reach the public release. If a page or browser feature behaves unexpectedly, users can report the issue to help Mozilla assess it.
Manage tracking protection and private windows
Firefox includes Enhanced Tracking Protection, which blocks known trackers while browsing. Its protection settings are available in the Privacy & Security area, where users can manage how the browser handles tracking content.
Private windows provide a separate browsing session that does not retain the session's browsing history in Firefox after the window closes. They are suited to a short session that should not appear in the browser's local history; private browsing does not make activity invisible to websites or network providers.
Send feedback while testing
Mozilla Beta sends data to Mozilla by default, and sometimes to its partners, to investigate problems and evaluate ideas. Feedback about a broken feature or an unexpected result contributes to the testing process ahead of a stable release.
