Bug#932256: firefox: WM_CLASS changed in firefox 68 from 'Firefox' to 'firefox'

[terroreek]

Package: firefox
Version: 68.0-3
Severity: minor

Dear Maintainer,

Looks like in firefox 68 the WM_CLASS changed from Firefox to firefox.
However the /usr/share/applications/firefox.desktop file still has;
StartupWMClass=Firefox

this breaks docks like plank because the WM_CLASS is firefox.  Changing the
line to;
StartupWMClass=firefox

fixes the problem.
