So there is no way to install both Flatpak Firefox stable and beta at present time ?
That's a regrettable constraint
Maybe it might be worth that I open a bug for that ?
You can have both branches installed in parallel!
But you have to use
flatpak make-current to switch between stable and beta or start them explicitly with:
flatpak run org.mozilla.firefox//stable
flatpak run org.mozilla.firefox//beta
Could this result in issues around local data being backwards incompatible between the versions? Some time after the flatpak had become official, I lost all my tabs—normally restored at startup—and "restore previous session" did not have them either. Still haven't gotten over that (I wasn't switching between versions, this just reminded me of it).
Anyways, look forward to packaging the dev edition for flatpak!
