Why am I limited to specific browsers with Norton?

It appears that Norton Security fro MAC does not support the Opera Browser, and, although this browser is less popular then Firefox and Safai, I can say working in the tech sector, it is very popular  amoung MAC users.

At soomepoint will Norton support the Opera Browser? At a cost of $79.00 per year for Norton, it would be a nice gesture for those of us  who want security and their choice of browsers.
