About Speculative Loading
This plugin adds support for the Speculation Rules API, allowing you to define rules for prefetching or prerendering certain URLs. By default, the plugin is set to prerender WordPress frontend URLs when the user interacts with a relevant link, but this can be customized in the admin settings. The functionality is supported in Chromium-based browsers such as Chrome, Edge, or Opera, but other browsers like Safari and Firefox will simply ignore it.Frequently asked questions
