This document lists policy-controlled features being implemented in browsers. It is broken into sections based on the standardization state of each feature. The names used here should be consistent between browsers implementing a particular feature, but there is no requirement that all browsers implement any single feature.
The exact definition of the behaviour controlled by each feature belongs in the spec which defines the feature. Those are linked where available.
These features have been declared in a published version of the respective specification.
