Is Firefox extension developed in Angular 2 will be accepted by Mozilla?

I want to build firefox extension using angular.
I read a few reviews that angular 1.X is banned by Mozilla. We can build firefox extension using angular version 1.X. but because of some security reason Mozilla banned angular extension and not accepted in the review. So I need to confirm that, is Firefox extension created in Angular 2 will be accepted by Mozilla?

Angular 1.6.6 is on the last hashes list, so as long as you don’t modify it, it should pass review. Not sure if there is a more up-to-date list:
