// PREF: notification interval (in microseconds) [to avoid layout thrashing]
// When Firefox is loading a page, it periodically reformats
// or "reflows" the page as it loads. The page displays new elements
// every 0.12 seconds by default. These redraws increase the total page load time.
// The default value provides good incremental display of content
// without causing an increase in page load time.
// How long FF will wait before rendering the page (in ms)

// PREF: page reflow timer
// Rather than wait until a page has completely downloaded to display it to the user,
// web browsers will periodically render what has been received to that point.
// How often the content is redrawn is controlled by the interval value.
// [NOTE] Lowering the interval will increase responsiveness
// but also increase the total load time.
// [WARNING] If this value is set below 1/10 of a second, it starts
// to impact page load performance.
// [EXAMPLE] 100000 = .10s = 100 reflows/second
