How to Auto Close In-App Browser Advertisements

In-app browsers, the ones that open when you tap a link inside a social media or messaging app, can't run extensions, so no ad blocker can close the ads inside them, Ultimate Adblocker included. They're mostly on phones, where Chrome doesn't run extensions either. The practical fix is to open the link in a browser that blocks ads: most in-app browsers have an "Open in browser" option in their menu. On a phone, that means a browser with built-in blocking, such as Brave, or Firefox for Android with an ad-blocking add-on. On a computer, open the link in Chrome with Ultimate Adblocker installed.
