Each vendor is moving at their own pace and in their own way, but the endgame is clear. With that comment, I was also referring to the depreciation of XUL more than the signing requirement.
No, its absolutely not. The new firefox addon signing requirements are a hundred percent more restrictive then the requirements to get listed on the chrome store.
Wrong. Chrome IS more restrictive, they don't allow non-Chrome Store add-ons AT all. With Mozilla's implementation all non-AMO add-ons need to do is go through the automated signing process. Which only takes a couple of minutes, at most.

This is wrong. You can drag and drop an extension into the Chrome extensions folder (or enable the developer mode in the extensions page) to install any extension in Chrome.
