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 :)

Convenient contact search service through social networks. Quickly finds working phones and emails of people you need, helps to contact them directly. Works well with LinkedIn and other networks.

SignalHire is an excellent tool for quickly finding accurate contact information. The interface is super user-friendly, making it easy to navigate and get the details you need in no time. It also integrates really well with other platforms, which is a huge plus. I’d definitely recommend it to anyone working in sales or recruiting – it saves a lot of time and makes the whole process a lot smoother!

Je ne donne pas mon numéro de téléphone à une appli que je ne connais pas...
