Evolution Default Browser

Having had issues with Chromium earlier today I then find that Evolution is opening Midori instead of Chromium.

On the XFCE desktop there is a default browser option in Default Programs but that is already set to Chromium.

Evolution has no such setting, so it requires a setting using xdg-mine instead.

xdg-mime default chromium.desktop x-scheme-handler/http
xdg-mime default chromium.desktop x-scheme-handler/https

If you use vivaldi, then this is the command for you

xdg-mime default vivaldi-stable.desktop x-scheme-handler/http
xdg-mime default vivaldi-stable.desktop x-scheme-handler/https

Close and open Evolution and it's all set. Very simple once you know what is causing it.
