Thats because flatpaks treat each apps directory as their own $HOME so instead of $HOME/.mozilla its $HOME/.var/app/{app_name}/.mozilla

Which is still fantastic dont get me wrong. But Mozilla hasn’t stopped hardcoding their Mozilla folder instead of the xdg dirs even throughf firefox issue tracker has had it on there for 20 years

This is why I use flatpaks. Keeps most of the offending the dotfiles in .var directory scoped to the app itself
