I normally have two or three browsers open. Most have been installed for so long I no longer remember what dnf calls them.
My wife, who also runs F39, has been having trouble with the ones she has, and I have yet to get around to trying to diagnose them. Today as a stopgap I tried to install some others for her, using dnf.
It couldn't find brave, falcon, opera, nor vivaldi. VERY Dumb Question : How do I look up what it calls them?
