Safari Pop Up Ads
Since updating I now have these Kia ads that pop up and take over the background of some websites like Postmark.

To stop Pop Ups, go to Safari > Settings > Websites > Pop Up Windows, and change the settings for the website to not allow pop up windows. This might not stop all Pop Up windows as some sites can still display an ad that takes over your entire screen and those cannot be stopped with this setting. In these cases, it is best to take up the issue with the particular website or not support a website that gives this kind of user experience. Ad blockers have had mixed reviews, as some of them are not able to stop all ads or they could even make the site unusable.
