Summary: Users have a bunch of contacts saved in a vCard file and are not sure how to move them into Thunderbird. That happens a lot, especially when switching from another email app. vCard files usually store contact details like email, names, and company information. And since Mozilla Thunderbird is a popular email client, most users want to import VCF to Thunderbird. In this blog, we’ll show you two simple ways to do it: one traditional method if you just have a small file, and another using the VCF to CSV Converter if you need to import contacts in bulk.

Common Reasons to Import vCard to Thunderbird

Here are a few common reasons people need to import VCF contacts to Thunderbird:

  • Shifting from another email app to Thunderbird, and wanting all contacts in one place.
  • When they want to move contacts from Gmail or Microsoft Outlook.
  • Bring contacts back from an old backup file.
  • Having lots of vCard files saved and wanting to combine them.
  • Keeping work or business contacts organized in one address book.

Traditional Method to Import VCF to Thunderbird

In this method, Thunderbird allows users to import contacts directly if they are using the updated version.

Step-by-step process:

  1. First, open Thunderbird on your PC and click Address Book from the main menu.
  2. After that, choose Tools >> Import.
  3. Now, select Address Books and hit Next.
  4. Then, select the vCard file (.vcf) option.
  5. Next, browse and choose your .vcf file from your PC.
  6. Lastly, click Open to transfer VCF contacts into Thunderbird.

Loopholes:

While the manual method is free and works, it has certain limitations to import VCF contacts into Thunderbird :

  • Users can only add one VCF file at a time.
  • Large VCF files sometimes don’t load properly.
  • You might end up with duplicate contacts.
  • Some contact details don’t show up the right way.
  • It’s not practical to use if you have a lot of contacts to move.
