Version 59.0a1, first offered to Nightly channel users on November 13, 2017
Firefox Nightly gets a new version every day and as a consequence, the release notes for the Nightly channel are updated continuously to reflect features that have reached sufficient maturity to benefit from community feedback and bug reports. Features listed here may or may not make a final release of Firefox.
In addition to these release notes, you can follow ongoing development on our @FirefoxNightly Twitter account as well as read our Nightly Blog.
Added new settings in about:preferences that allow you to stop intrusive websites from asking you to receive notifications or access advanced device features such as camera and geolocation, while still allowing websites you trust to use these features.
