Finally, given the ever-declining quality of articles showing up on my Google Discover feed, I decided it was time to remove it. Ironically, I saw an article with a how-to on the feed itself.

From there things snowballed. I reinstalled #novalauncherprime so I could get rid of the Google search bar at the bottom and use the #firefox widget.

I'm still using Google as my search in the widget, for now -- but at least it guarantees all my searches open in Firefox, not Chrome.
