Thanks for filing this bug. I double checked on Chrome, and it looks like they support alerts() from the BG context as well. The only difference is that we do not eventually show the checkbox to prevent extensions from creating additional popups. This is a gap that is being tracked by 11385130. Please refer to that bug moving forward; since this is supported by Chrome, I’m going to resolve this as by design.
