The StartupWMClass is no longer valid, and it leads to a pixelated icon being used, instead of the high quality included icon.
xprop shows the following WM_CLASS values:
WM_CLASS(STRING) = "Navigator", "librewolf"
Since "Navigator" is quite generic, I just changed it to "librewolf" instead of "LibreWolf" which is not actually on the windows.
