Works very well, except when Amazon doesn't anticipate the user going to "smile...". For example, "www.amazon.jobs" shouldn't redirect to "smile.amazon.jobs". Having an exception list available via options would be appreciated! :-)

Infinite redirect when not logged in

Works good with no fuss, but needs to not redirect https://www.amazon.com/iss/credit/storecardmember urls, or have the ability for users to whitelist such Non-Smile Amazon pages.

Works great
