declarative configurations of firefox extensions

teto commented 8 months ago

Description

We support declarative configuration of firefox but what about its addons ? I recently had to setup a new machine and lost access to my firefox sync profile and there are some extensions I would like to keep my settings via nix instead, for instance this one https://addons.mozilla.org/en-US/firefox/addon/refined-github-/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=search which I like but has a few bad defaults.

I have no idea how this works, if it's even possible. I suspect addons can use any mechanism they want unless they care about firefox sync. I found https://discourse.mozilla.org/t/in-which-file-are-stored-an-add-on-settings-options/26064 but I have no storage.js in my ~/.mozilla it looks like

NB: I know about https://github.com/nix-community/home-manager/issues/606 but wanted a distinct more focused issue

I wanted this for a long time too!

I did some digging and found:

Firefox's own management of extension configuration goes in these 2 files:
- ~/.mozilla/firefox/<profile>/extension-settings.json # couldn't really decipher much of this
- ~/.mozilla/firefox/<profile>/extension-preferences.json # this has permissions and origins for both themes and extensions
Extensions themselves can have their own files in any location within a Firefox profile for their config (assumption)
- The containers extension saves its container config in ~/.mozilla/firefox/<profile>/containers.json
- Extension state (not exactly config) are stored in ~/.mozilla/firefox/<profile>/storage/default/moz-extension+++<uuid>

I've only recently learnt how to create NixOS modules, so, I can't help much in actually making a declarative config module (though I might later down the line) but yeah this definitely seems quite messy and/or volatile in terms of what config goes where. Perhaps someone with hands on experience messing with Firefox config would have a better idea.

I don’t think there is a way to configure extensions in general except through policies and most extensions don’t seem to support policy-based configuration.

I think we should close the issue as I don't think there is anything home-manager can do.
