Would be great if Microsoft didn't break it (Outlooks loads indefinitely).

Totally broken. UI pops up, but no actions are triggered.

Works well but it would be great if you could customise the client it opens to as some people don't use Gmail or Outlook.

INSTALL IT!! Open your Protonmail in Firefox, click the banner in the browser to make it your default mailto:. Then you can also select certain emails to open work emails in Outlook, and you can still open Gmail from mailto: links as well. So, you can use ALL THREE(3) !!! Love it!

This extension is just a poorly arranged copy of mailgo (https://mailgo.dev/). It implements the same functionalities with the same graphical elements, not cool.

Good plugin that allows you to chose your desired email application, 5 stars.

The plugin is in good design and make my life convenience :)
