vCard Card Viewer by vCard

With vCard, see .vcf contact cards immediately on your Firefox browser window.

NOTE: Why vCard asks to access all websites

Contact files can come from any site. To catch them, the add-on checks only the file type of each page you open and steps in only when it's a contact file. It never reads page content, never sends anything anywhere, and keeps nothing. Feel free to inspect the code: see the last section.

How it works

Click a .vcf link (the "Add to contacts" button on websites, digital business cards, event pages) and vCard Card Viewer opens it as a clean contact card, right in the tab: photo, name, title, company, phones, emails, websites and addresses, laid out like the contacts app on your phone.

Your data stays yours

• No tracking, no analytics, no ads, no accounts.
• Nothing is sent to us or to anyone else. The only network request is to the site you clicked, to load that contact file.
• The card is read and drawn inside your browser. Photos come only from inside the file; remote image links are never loaded.
• Nothing is stored: no history, no copies of your contacts.

What you can do from the card

• Call, text, email or map any detail with one click
• Download the original .vcf when you do want to save it
• View the raw file
• Open one link the normal way when you want the plain download
• Drop a .vcf from your computer onto the viewer (toolbar button)

Handles the contact files out there

Feel free to inspect the code

Nothing is hidden: about 680 lines of plain, unminified JavaScript, HTML and CSS, with no outside libraries. The add-on file (.xpi) is an ordinary zip archive: download it from this page's version history, rename it to .zip and open it to read every line. Licensed under GPL v3: anyone may reuse it, but every copy must stay open source under the same license.
