Edge on (android, not sure about iOS) mobile has "Adblock Plus" built in that can be enabled. Sure, I'd rather UBlock Origin like on my pc but when/if that stops working on Edge desktop, I wonder if they'd add a similar built in thing to desktop...
Adblock Plus, Created to Protect Users From Ads, Instead Opens the Door
in 2011, Adblock Plus was altered and became a tool that, instead of blocking bad ads, allowed ads it deemed “acceptable” to be seen, often for a price — a controversial move that has positioned it as a gatekeeper between advertisers and its huge user base.
“We are called Adblock Plus, and for branding reasons, we are not going to call ourselves something different. But if we could, we would call ourselves something like ‘web customizer,’ because that’s really what we want to do for our users.”
It's better than Chrome (which has no ad-blocker at all) but I find it doesn't block those insane pop-ups like uBlock on Firefox do. Kinda wish Microsoft would just bring their Add-on store on mobile Edge.
