With the removal of Flash, there is no longer the need to return anything for navigator.plugins and navigator.mimeTypes. These APIs were used primarily for a) probing for Flash player support, or b) fingerprinting. As such, we'd like to return empty for these two properties. Gecko already switched to returning *only* Flash starting with Firefox 52, and returning empty as of Firefox 85.

Motivation

Improve interop, remove fingerprinting vector, general API cleanup.

Note that this is not the removal or change of any API, it is merely the return of empty arrays for these two existing APIs.
