Hi I am not sure that I fully understand your question, but if you wish to stop notifications from a web site, I might be able to help. From the Firefox for Android home screen swipe from right to left twice to display the '''History''' panel. Look down the list to find the site that is providing the notifications, then long press on it to select to remove it from your history. Next time you visit the site, you will have the opportunity to decline notifications from that site.
