Perhaps you’ve seen the official take title [Firefox removes core product support for RSS/Atom feeds | Use Tables!]Firefox removes core product support for RSS/Atom feeds | Use Tables!=

“These features have long had outsized maintenance and security costs relative to their usage”, which amounted to 0.01 percent of sessions.
