Enigmail provides support for GPG so you can use it in the email client. As it is an add-on for Thunderbird, we firstly have to:

  1. Open Thunderbird
  2. Log into it

You’ll be asked whether you want Thunderbird to be allowed to access your contacts or not, choose whichever option you want.

After opening Thunderbird:

  1. Click the menu button (three lines symbol) at the top right corner of the window
  2. Choose option Add-ons
  3. Go to the Extensions tab in the menu on the left side
  4. Type Enigmail to the search bar at the top of the page and click enter
  5. Choose Enigmail out of the results and click Add to Thunderbird
  6. Click Install now in the installer pop up window

Once Enigmail is added, notification bar saying Enigmail was successfully installed will appear at the top of the page. You can see it also appeared in the Add-ons Manager tab.
