I have installed the Messenger for Desktop app on my 16.04. Everytime I launch the application I get this javascript error seing on screenshot below
However when I click OK the the app launches properly. I haven't detected any issues so far, however I was wondering if anyone else has faced the same issue and how to solve it.
Edit I have noticed that I don't get a notification or any indication when some of my contacts texts me when the app is minimized. I'm not sure if this is a bug occured from this issue or whether is missing from the linux version in general (which probablly is still a bug)
