Protonmail in eMail client

So far, Protonmail has evaded us with eMail client support.

Now the option exists via the Protonmail Bridge, which is available for Mac OSX, Windows 10 and GNU/Linux.

Here’s how I set it up in Ubuntu:
From the protonmail.com/bridge/install page, click on the GNU/Linux to download the .deb file. Double-click on it and launch the software manger. Install.
Unfortunately, right now the only email client that works with this Protonmail Bridge is Thunderbird, which is a Mozilla product. I had previously deleted this app out of protest of Mozilla’s anti-speech behavior but since it’s free and open source, and the only option for now, I will have to live with it. If you do not have this program, in a terminal, type:

sudo apt install thunderbird

Before you setup Thunderbird, you will need to launch and configure the Protonmail Bridge. All of the instructions for configuration are here: https://protonmail.com/bridge/install
