Troubleshootings that I tried: Checking all the filters, updating my browser, scanning for malware by Samsung's default app.
Problem: https://myreadingmanga.info/ is an online manga reading site, and these ads appear at the top and bottom of every manga. The screenshots are just examples of the ads in one of the mangas. Also, the Adblock app doesn't always success in blocking pop-ups on this site.
Screenshots are taken in Samsung browser's desktop version. Ads in the mobile site are as wide as the manga itself.

Browser: Samsung Internet ver 7.2.10.33
Operating system: Android ver 5.1.1
Adblock ver 1.3
I tried both but I couldn't make it work (I'm kinda low-tech, sorry!) In ABP for Samsung, I manually added your filter by tapping on 'Add another filter list' and entering https://bpaste.net/raw/4ccbed53f7c9 but the ads are still there.
It's odd that your quick fix worked in my Chrome (windows) but not in my Samsung browser.
