Thanks for feedback. I promise that I won't add any dangerous new permissions. I care deeply about privacy and I'll make sure no tracking can ever be done. This addon is one of the few ones that doesn't use a favicon database that can possible track users (like the http://www.google.com/s2/favicons?domain_url={Domains_URL_of_a_tab}. that so many addons use). If I ever need to add a new permissions most probably I will provide it only as an optional permission that can be activated on demand (or not).
