Not all application windows are matched properly to desktop files

[probonopd]

Firefox (when installed on FreeBSD by pkg) cannot be launched when pinned to the Dock because the Dock cannot figure out the corresponding .desktop file.

• xWindowWMClassName is used in utils.cpp to find "matching" desktop files; xWindowWMClassName of Firefox is Navigator
• utils.cpp tries to match Navigator to
  • The name of desktop files (e.g., Navigator.desktop - no such file exists)
  • StartupWMClass in the desktop files (e.g., StartupWMClass=Navigator - no such key exists)
  • Icon in the desktop files (e.g., Icon=Navigator.png - this does not match)
  • Exec in the desktop files (e.g., Exec=Navigator - this does not match)

If you add StartupWMClass=Navigator to /usr/local/share/applications/firefox.desktop manually then you should be able to pin Firefox, but it also does not work as-is for many other applications.

I can see why this would be an issue on FreeBSD/helloSystem, however I'm not able to reproduce this issue under Arch Linux/CyberOS. I can pin it to the dock just fine, and I can start it from the dock.

Seems like the Firefox desktop file, at least on Arch Linux, has StartupWMClass=firefox: https://github.com/archlinux/svntogit-packages/blob/packages/firefox/trunk/firefox.desktop#L122

Can you check if Firefox's .desktop file has StartupWMClass=firefox by default on FreeBSD? @probonopd

It does not have that key.

Hmm. I have no idea how to help with this. Maybe you or @rekols could, you do have write access.

[probonopd]

Should it be StartupWMClass=Navigator (works for me) or StartupWMClass=firefox?

I have no idea, but I'm pretty sure you can repackage Firefox in helloSystem with the necessary changes. StartupWMClass=firefox works for me, but the safest bet for you would be to choose one that works the best.
