The coupons in the bottom right corner have x-notifier as a sponsor on them. There is also a prompt to disable the notifications from said coupons, but when you click on the disable mark it doesn't disable the coupons for more than a second. Is there a way to get rid of these intrusive adds or coupons permanently?
Superfish?
You can look in X-Notifier's Options and see if you have 'Use similar product search (Superfish)' enabled... uncheck the box.
