How to stop websites asking to send notifications?

There is no way to stop as as far as I am aware. Whilst it is a little irritating, it is being done with your best interests in mind to make sure that you have the option to agree/disagree with getting messages when you are browsing or to receive content that is tailored to your location (which could be either really useful, or just a bit creepy).

Google Chrome does.
