Quantum Flow was a cross-team browser responsiveness improvement effort that ran throughout 2017 and culminated in the release of Firefox Quantum in November of that year. You can read more about the release of Firefox Quantum in this article and learn about our latest performance triage process here.

Bugzilla Query Lists

The Quantum Flow (QF) initiative is a cross-component effort to improve user perceived responsiveness and performance. Since QF is cross-component we are unable to use the component specific fields in Bugzilla such as Priority etc. Instead we will annotate interesting bugs with whiteboard tags and attach them to the appropriate QF meta bugs.
