Don't believe everything you read on the internet.

Yes, the text on that page can be interpreted as supporting your position. Still, "Offer a password manager..." is not quite the same thing as "silently read all of your passwords and do whatever the extension wants with them..." I have a very hard time believing that the latter is the case and that no one has sounded the alarm on this yet.

Also, add-ons have been deprecated in favor of extensions.
