page when browsing LinkedIn, Twitter & Facebook and in the nav-bar.
Click on the extension to check if data is available for the
profile/website. Check Auto-Open for the extension to open whenever
you visit a profile page. When Swordfish finds contact information
for a profile, a preview of the details appears with "Show" button.

contact, "Show" will not display button and no credits are used.
