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.

You used to be able to. You can't now.

You can, it just shows a warning about developer mode.
