Hello friends.
I just need Firefox 52 ESR.
I’ve copied official Mozilla snapcraft.yaml and corrected it to my needs.
It is built nicely using lxd and installed.
It starts normally and navigate to any site.
However everything is white.
Some interfaces are automatically connected, others (like camera) are not. However a developer can request auto-connection of them via a Snap Store assertion. Your snap isn’t in the store, and you installed manually so you don’t have that assertion, so they don’t auto-connect. So you can manually run snap connect firefox52:(interfacename).
I imagine browser-support is a crucial one.
