About Firefox Nightly
Get a sneak peek at our next-generation web browser, and help us make it the best browser it can be: try Firefox Nightly. Nightly is an unstable testing and development platform. By default, Nightly sends data to Mozilla, and sometimes our partners, to help us handle problems and try ideas. Firefox Nightly gets updated 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. Allow the browser toolbox to enable/disable multiprocess behavior on-demand (bug). The user can switch between two modes. The devtools console is now significantly faster! If you are a developer who heavily uses the console, this should be a substantial quality of life improvement. Firefox 100 goes out today! A milestone release, but also business as usual! Congratulations to contributors who helped get Firefox 100 out the door!
