This extension hijacks searches to include their referral tag to steal rep and/or money for themselves. When directly going to www.google.com and running a manual search in the search bar, this addon hijacks the search to include its referral tag, making Google think this app initiated the search. This is similar to how Honey steals money via referral codes. Go to Google, run a search, then disable the addon and do the same thing. Compare the URL bar.
