Package: firefox-esr
Version: 60.1.0esr-3
Severity: normal
X-Debbugs-CC: gland...@debian.org

Dear firefox-esr maintainers,

I am reporting a problem about WM_CLASS; for its background, please take a 
look at obsoleted https://bugs.debian.org/682371 and freedesktop.org Startup 
Notification Specification [1].

TL;DR:

* Current WM_CLASS for firefox-esr: WM_CLASS(STRING) = "Navigator", "Firefox"
* StartupWMClass as written in firefox-esr.desktop: "Firefox-esr"
* Buggy result: Multiple firefox-like icons will appear on modern desktop task 
lists (e.g., GNOME Shell)

* Solution: Either patch firefox-esr src and set its WM_CLASS back to Firefox-
esr, or modify firefox-esr.desktop and set StartupWMClass=Firefox (I personally 
dislike this since it will cause confusion when firefox and firefox-esr are 
coinstalled).

P.S. I will close #682371 now since iceweasel has disappeared for ages.
