Would also love to see Firefox Developer Edition on flathub.
Worth noting that there is a flatpak repository for Firefox Nightly and Firefox Developer Edition https://firefox-flatpak.mojefedora.cz/ however if I remember correctly it hasn’t been updated for a while.
Well, I’m on the team which wants Firefox Dev on flathub.
I have tested the repository mentioned by @sonny but it is not been uptaded for a year or more… maybe if the community contact mozilla about our request they give us attention?
Has somebody tried to contact them?
I have submitted the request to Firefox Developer Edition flatpak - Mozilla Connect
Please vote 
Voted, Sonny.
How do you manage now ?
Are you after downloading FFDE and installing it manually ?
I’m on Ubuntu and did it manually on a user account so it can update itself - which it does with tedious frequency.
Thanks for submitting that!
There is also the official bug report here:
And mozilla discussion thread:
https://discourse.mozilla.org/t/flatpak-developer-edition/126782
There are now some listed blockers listed which make more sense. It is actually due to an upstream problem with Flatpak not supporting additional channels (beta, nightly, etc.), per application, and the ticket to resolve this was closed as Not planned, discussed here:
So Flathub just implements a separate repo to allow one beta channel per app. There is a proposal for Firefox to use per-branch app id’s, but a better idea IMHO is what I proposed in the comments there:
Since there are actually four channels (Stable, Beta, Developer, and Nightly), and beta is already the official Flathub ‘beta’ channel for Firefox main, what if we instead just released Firefox Developer Edition on Flathub, with Nightly as the so-called ‘beta’ channel for it? This makes sense because Dev edition is based on beta, and nightly a version ahead of it.
It also has the benefit of exposing the stable edition for most users, and the developer edition for developers, while making the least stable versions not as prominently advertised to general audiences.
There is some pushback but hopefully more people agree with my suggestion ![]()
