What is Firefox Nightly?

Get a glimpse of our innovative web browser by exploring Firefox Nightly, an experimental platform designed for testing and development purposes. As Nightly is in an unstable phase, it automatically collects data to send to Mozilla and occasionally to our partners, which aids in troubleshooting and exploring new concepts. This version receives daily updates, with release notes consistently revised to highlight features that have reached a level of maturity suitable for user feedback and bug reporting. Among its noteworthy features is the browser toolbox, enabling users to toggle multiprocess functionality as required (bug). Users can effortlessly switch between two operational modes, and developers will benefit from the improved speed of the devtools console, which greatly enhances the overall experience for those who utilize it. Today marks the exciting release of Firefox 100, a significant milestone that underscores our ongoing dedication to excellence! We extend our heartfelt appreciation to all contributors whose hard work and commitment have made the launch of Firefox 100 a reality, paving the way for future advancements.
