The preference content.switch.threshold controls Firefox // responsiveness to your input (i.e. responsiveness to the UI) at the expense of slightly slowing the page load. Since // you’ve already minimized the page load time, that shouldn’t be too much of a sacrifice. // Firefox has two modes of user interaction with web pages that are still loading: high frequency interrupt mode and // low frequency interrupt mode. The high mode better tolerates user interactions with the content. What this controls is // the number of microseconds of inactivity that will activate low frequency interrupt mode. In other words, it controls how long // you have to do nothing before Firefox assumes you are waiting for the whole page to load. // Firefox is configured to apply low frequency mode after 0.75 seconds of user inactivity. Every time the browser goes to // low frequency mode, it becomes faster at loading pages. Therefore, it is beneficial to reduce the time it takes for FF // to enter low frequency mode. Thus, a value of 0.25 seconds (250000 ms) should be fine for that purpose. // "Raising the value will make the application more responsive at the expense of page load time.” // [1] https://www.download3k.com/articles/How-To-Optimize-Firefox-By-Tweaking-Hidden-Settings-In-The-about-config-Page-01955#content-switch.threshold // [2] https://botw.org/articles/firefox-about-config.htm // user_pref("content.interrupt.parsing", true); // [HIDDEN] default=false // user_pref("content.switch.threshold", 250000); // [HIDDEN] default=750000 // PREF: Increase speed of gradual rendered elements // The function of this setting is associated with the gradual display of rendered elements on a page. // In practice, a page is not loaded completely at once, but it is loaded gradually.
