The use of webRequest used to cause addons to start early during Firefox startup. This has changed to only use webRequest blocking calls. non-blocking calls no longer cause an early startup for addons.
The Compatibility sidebar panel in the DevTools Inspector already available on pre-release channels will become available on the release channel in version 98 . It provides compatibility warnings for the CSS properties used on the selected element, as well as for the overall page.
Developers may use it to detect web-compatibility issues early, without having to test in each browser. All compatibility data are pulled from MDN.
The <dialog> HTML element already available on pre-release channels will become available on the release channel in version 98.
