What are those ads that slide in from the low right corner of my screen and how do I kill them?

Factual Questions
1

Lately, instead of pop-ups, some websites use square ads that slide in from the low right corner of your screen. Googling “blocking slide-in ads” gives pointers how to stop that.

However, I have similar notifications on my home screen, when I’m not on the Internet. Apparently I clicked the wrong box on some news sites and now I’m spammed. These slide in news notifications and ads are mostly about news items, not so much commercial ads. It doesn’t help to click these slide-ins away, as they will just be replaced by another one. And then after a few minutes they go away and come back later.

I don’t see anything in my settings menu on how to kill these slide in pop-ups. And I can’t google them because I don’t know what they are called. Does anyone know?

I think we need more info. Is this on a phone/tablet or a regular computer? What do you mean when you say ‘home screen’ and ‘not on the internet’. That not on the internet is an important clarification since it can mean the difference between something serving you ads and adware/malware/virus if you’re getting pop ups when not connected.

If you are on Win10, you probably want ‘Notifications and Actions’. If you start typing “Notifications” in the search bar, then “Turn app notifications on or off” will come up pretty quickly. Try there for starters

Starting yesterday, Chrome started spamming me with these notifications. That’s my guess (sorry for the non-GQ answer, but there’s not much here to go on). In the upper right, there may be a gear that you could use to block them one by one, or go to Chrome settings, search for Notifications, and turn them all off.

I’m not sure what browser or device you’re using, but I’ve been recently having a similar problem on my MacBook Pro using Safari 12.1.2

In fact, I was quite irritated by pop-ups at the bottom third of my SDMB screen. Not only did they block the screen, but when I hit the back button, the screen never went back, it just reloaded the same page with the same lower screen pop-up.

I checked in my Preferences / Security and noticed my Javascript was enabled after the latest update I did. I disabled Javascript again and problem has gone away. I’d read some time ago that javascript should disabled due to security vulnerabilities, so I did.

You may have turned on notifications from one or more Websites.

Here’s how to get rid of them in Firefox. Here’s how to get rid of them in Chrome.

Thanks all! So they’re called “Notifications” . I think I accidentally allowed a few websites to send me those, when I though I was clicking on a yes-yes-go-away-cookie permission window. Sneaky bastards.

It’s fun to google “slide in ads”. The you can see the marketing people’s thoughts behind that type of ad.

I use uBlock origin (not just plain uBlock) and I never see any of these. And I don’t even see the other ads that infest SMDB at times. (Once while in the hospital, I had to access SMDB in a computer without adblockers. I found it (and many other websites) almost unusable from the intrusions.)
