Sorry if I’m missing something blindingly obvious, but… is there an officially supported way to add feeds to NNW from your browser, especially if your browser is Firefox? And/or is there a way to ask NNW to register itself as the default handler for feed: URIs?
We have a Safari extension but not a Firefox extension. (It would be nice if we did!)
Unfortunately, sandboxed apps (such as NetNewsWire) can’t set the default handler for feed: (or any URL scheme). NetNewsWire does declare that it handles feed: but it can’t tell the system that it’s the default handler.
Interesting. Would you be receptive to a PR for an MV3-based extension for Firefox and Chromium-based browsers? I’ve had a look at the Safari extension code and it seems like it would be fairly straightforward to replicate since the feed selection logic is all app-side.
