 * According to this listing description:
 * > Other browsers such as Safari and Firefox will ignore the functionality with
   > no ill effects; they will simply not benefit from the speculative loading.
 * Why is FireFox not supported? According to Mozilla it seems supported:
   [https://developer.mozilla.org/en-US/docs/Web/Performance/Guides/Speculative_loading](https://developer.mozilla.org/en-US/docs/Web/Performance/Guides/Speculative_loading)
   And has been well supported in recent times:[https://caniuse.com/?search=prefetch](https://caniuse.com/?search=prefetch)

 * Firefox supports the older `<link rel="prefetch">` resource hint, but not the
   newer Speculation Rules API. The new API includes many benefits over `<link rel
   ="prefetch">` including:
    - Full prerender as well as prefetch
    - Automatic link finding
    - Different eagerness levels
    - Better DevTools support
    - More consistent behaviour (particular with cross-origin prefetching/prerendering).
 * It is no longer recommended to use `<link rel=prefetch>` for navigation prefetches,
   and instead to use the new Speculation Rules API for this, and to only use `<
   link rel=prefetch>` for subresources.
 * However, we have asked [Firefox’s position on this new API and they are positive on it](https://github.com/mozilla/standards-positions/issues/620#issuecomment-2703979191),
   so hopefully that means support will come to Firefox at some point, at which 
   point this plugin should support it.

 * [@tunetheweb](https://wordpress.org/support/users/tunetheweb/) Thank you so much
   for the detailed explanation, evaluation and creating a Github post! I’m very
   pleased to hear there is interest from Mozilla to support the newer Speculation
   Rules API. I’m a huge fan of FireFox so this will be a lovely treat. 🙂
 * Warm regards,
   Josh
