I mean it does send out a unique code for that browser.
Sure that is what it already does but this addon makes it
an opt in. You tell they you agree to be known sort of?
Can not that be exploited?

BrowserID is an easy way to sign into websites.
Instead of making up a hard-to-remember username and password
for each site, BrowserID lets you use your email address and a single
password to sign in to any site that supports it.
This article shows you how BrowserID works and
how you can get started using it.
