No longer works in Firefox?

    Do Firefox and Safari no longer process the JS that triggers preloading pages?

    I generally use LiteSpeed instant-click, which stopped working, and installed Flying Pages, which I used before migrating to LiteSpeed. Same behavior in both.

    No preloads after the page loads, nor with hovers.

    Neither Firefox nor Safari work, yet Brave browser preloads pages flawlessly. I haven’t seen any mentions of Firefox in this Support forum. There are no errors or warnings in DevTools.

    I don’t think this is Flying Pages’ fault, as I think something in Firefox and Safari has changed. I swear this must have worked before because Firefox is my primary browser.

    The page I need help with: [log in to see the link]

    – Chromium is guaranteed to work
    – Safari – Not supported by default, but can be enabled
    – Firefox – Not sure about it.

    You can check their status here: https://caniuse.com/link-rel-prefetch

    Alternatively you can run the following code in your browser to verify:

    const prefetcher = document.createElement("link");
const isSupported =
    prefetcher.relList &&
    prefetcher.relList.supports &&
    prefetcher.relList.supports("prefetch") &&
    window.IntersectionObserver &&
    "isIntersecting" in IntersectionObserverEntry.prototype;
console.log(isSupported)

    Thanks for all the tips.

    It appears that some privacy setting in general prefs turns off Prefetch. I turned it back on and got some preloads to work, but not hover.

    Restarted Firefox and the prefetch setting reverted to False. about:config even shows that as not a default setting, so *something* is toggling that automatically.

    Thanks!
