Highly accurate and easy to use
Excellent add-on for finding emails and phone numbers. Unlike other tools that give you dead contacts, SignalHire keeps a low single-digit error range (~1–6%). Super reliable and integrates perfectly with Mozilla.

SignalHire is an excellent tool for recruiters and sales professionals. The service helps find contact information for potential candidates or clients without lengthy searches. The convenient browser extension allows you to obtain email addresses and phone numbers directly from social network profile pages. The accuracy of the data and the ability to integrate with CRM systems are particularly impressive. The only drawback is the not-so-cheap pricing, but considering the time saved on searching for contacts, the investment fully justifies itself for professionals in HR and sales.

After trying countless tools that only work with Chrome, I was thrilled to discover this extension works flawlessly with Firefox! As a Mozilla loyalist, I'm used to being left out, but not this time. The Firefox integration is smooth and responsive, giving me all the same powerful contact-finding capabilities without switching browsers. It's synced perfectly with my existing workflow, and the data accuracy is impressive. Finally found a solution that respects my browser choice while delivering exceptional results. Mozilla users, this is the prospecting tool we've been waiting for!

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 :)
