I want to get instant notifications for new emails and I don't want to install and configure an extra program for that. Thunderbird shows notifications, so does Gmail webapp. But both of them work only as long as they are open and running (or minimized).
Is there a way to have Thunderbird show notifications without keeping it open (at least the GUI)?
OS: Ubuntu 14.04
I recommend (and use) FireTray, which you can get at https://addons.mozilla.org/en-us/thunderbird/addon/firetray/.
It will keep Thunderbird running in the background, and then notify you of new emails.
