It's not "chasing chrome compatibility", it's sharing the same base.
Firefox wants to add its own APIs to webextensions. Chrome will too. They may not always match with each other with the newest APIs. It cuts both ways here, it's wrong to characterize it as something where only Chrome will be adding features and Firefox will play catch-up. Firefox is "copying Chrome" only as far as copying the base API.
