"Create your Free Account Sign up to get free credits" First welcoming text at login when installing the addon. I love the emphasis on "free" compared to the $79/mo minimum subscription price :| Anyway there's other extensions that are client-side only skimmers, those work great and free and fast :)

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

SignalHire - find email or phone number requires a lot of sensitive permissions. Exercise caution before installing.
