I accidentally subscribed to news notifications from a stock market site and now I am getting notifications every few minutes that are irritating me.
I do get other notifications for email I'd like to keep. How can I find which alerts are active on my system and turn them off? Or failing that, turn them all off.
I am working on a Linux Mint 17.3 system, it is my own (I have the root password).
P.S. The Zacks.com site has an alert area, but it says I am not subscribed. I thought this was the site, but the alerts don't show who they are from, and I was surfing other market sites yesterday, too. So I'd just like to know how to look at a list, or if getting rid of cookies would work, or something like that.
