"Doesn't load on 19.3"
"Seems to work fine except for one thing. I can't connect to my KeePass database with the KeePassXC addon. My KeePassXC client doesn't see the Firefox flatpak browser either. I have a strong suspicion this has something to do with the flatpak sandboxing the browser. Whether it is or not, this is a killer bug for me. Therefore, I'm going back to the original Firefox and will wait until this flatpak is better polished."
"Doesn't work. Says I need the latest flatpak version so I added and install the flatpak PPA. Now after trying to install, it sya "Type of message '(ayussass)', does not matach expected type '(ayussasass)'"
"Simply doesn't work. Using LM 18.3 Cinnamon 64 bit."
