+ * the page is refreshed, and the default interval for this function is set to 0.12 seconds (in other words, the page displays
+ * new elements every 0.12 seconds). However, since these redraws will increase the total page load time, you can set a new value
+ * of 500000(ms), which corresponds to 0.5 sec. ***/

+/*  Improve the browser’s loading times
+ * 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.
