Have Thunderbird 52 running in background
Just like what people asked here in the past (How to run Thunderbird in the background?, Start Thunderbird in background), I would like to have Thunderbird running at all times during which my PC is turned on and notify me of new e-mails.
In the past, many suggested FireTray, which is not available for Thunderbird >50.
What would be your best workaround?
I have Ubuntu 16.04/Thunderbird 52.
