Minimizing to tray fails: closing firefox window closes the tray icon

[moritzaugustin]

Both closing via Ctrl+Q (or Ctrl+W when having open the last tab) closes the FireTray icon in the gnome desktop's system tray on my system. The expected behaviour would be that firefox is minimized into the tray and not fully closed. Note that the "closing window hides to tray" preference is set.

I am using the gnome desktop with ubuntu 14.04 packages, i.e., firefox 44.0+build3-0ubuntu0.14.04.1 and have installed the FireTray version 0.6.0.1-let-fixed

Issue is still present after upgrading firefox to version 44.0.1 (in ubuntu trusty package notion: 44.0.1+build2-0ubuntu0.14.04.1)

Issue present on ms windows 10, too. Same firefox version 44.0.1.

If further information is needed please tell me.

Similarly, this happens in Thunderbird, also on Ubuntu (16.10). Additionally, clicking on the "X" to close the window normally closes to tray but sometimes it just closes and wham Thunderbird is no longer running and you're left wondering why that person hasn't emailed you back!
