Why does Microsoft Edge consume so much RAM with ads?

It’s common to notice Microsoft Edge slowing down your machine by gobbling up gigabytes of RAM when you have multiple tabs open, especially when they load heavy dynamic banners and invisible background trackers.

Crushing memory usage in Edge

Excessive RAM usage is caused by the execution of ad scripts. AdBlock Network prevents them from entering memory. The extension performs asynchronous read-only requests to multiple independent endpoints to update the firewall, blocking the download of heavy ads at the Address layer before they consume memory.
