Manage firefox extension settings declaratively

[llakala]

The people say it's impossible, but i see a working sqlite database which controls redirector settings. Ideally, the correct sqlite databases would be copied in to the right places on first boot. This may be too hard for little old me, though.

Extensions that would ideally be managed are currently:

• Ublock Origin (has been done)
• Dark Reader
• Refined Github
• Redirector

Maybe we can apply settings without sqlite just using the "3rdparty" settings like this. However, I fear this might not work for how redirector handles its settings.

Also a good reference for declarative extension management: https://github.com/Poly2it/nixos/blob/ef6c9e99a27bd059068e68b77665a7048a68704c/home-modules/firefox.nix#L160

And a good folder representing current capabilities. DarkReader config doesn't seem possible for the time being.
