Add function to firefox

1

I want to make a modification in firefox so that it refreshes the page automatically after a period. That is, I want to "fire f5" in a certain time interval and on a certain page. I've been reading about extensions of firefox, and I have seen that they are made in xml, but I found nothing that tells me that I can change the structure of the browser with just that language. What language should I learn to make this change?

Thank you!
