Firefox 72 release note for developers
https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/72

The release note for developers lists news and changes on APIs or developer tools that may be used by web contents developers or firefox plugin developes.

You can get overview of the new release changes and prepare to manage influence on WebClass functions or your learning materials.
