Description of problem: The most recent Firefox update [1] in f33-testing dropped the libXt dependency, which is still needed:

XPCOMGlueLoad error for file /usr/lib64/firefox/libxul.so:
libXt.so.6: cannot open shared object file: No such file or directory
Couldn't load XPCOM.

  firefox  84.0.2-1.fc33 -> 85.0-5.fc33

Removed:

  libXt-1.2.0-2.fc33.x86_64
  libmcpp-2.7.2-26.fc33.x86_64

  xorg-x11-font-utils-1:7.5-47.fc33.x86_64

Added:
  bluez-libs-5.55-1.fc33.x86_64
  sudo-python-plugin-1.9.5p2-1.fc33.x86_64

I of course applaud the effort of getting rid of more X stuff, but it seems even firefox-wayland needs this libxul component. And of course the "firefox" package needs that dependency as long as there is no explicit "firefox-x11" package (perhaps there should be one day, and firefox-wayland becomes the default?)
