User Agent: Mozilla/5.0 (Mobile; OPENC; rv:28.0) Gecko/28.0 Firefox/28.0 Build ID: 20140526135818 Steps to reproduce: When I receive a vcf file as an attachment, and clicks to open it Actual results: I get a message that says there is no application installed to handle this file type. Expected results: It should have offered me to view the file or import directly to addressbook. It is a very common method of sharing contacts and is widely supported on nokia and android powered phones.

Sorry that we didn’t fully support vcf right now. We could import vcf file from memory card to the contacts, maybe bug 974589 could makes contacts app able to import the contacts in vcf file directly.
