"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.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious.
This is determined by the publisher and the Firefox add-on reputation on
Firefox Browser Add-ons, the amount of time the Firefox add-on has been
around, and other signals about the
Firefox add-on. Our algorithms are not perfect, and are subject to change
as we discover new ways to detect malicious extensions. We recommend that you always
exercise caution when installing a Firefox add-on.
SignalHire - find email or phone number has earned a fairly good reputation and likely can be trusted.
Risk likelihood analysis details
