Ghostery Slowing Down Safari Performance? Here’s a Fix

Ghostery is a popular content blocker that aims to block annoyances, trackers, pop-ups, ads, and other web clutter. When implemented properly, it often even helps to speed up Safari performance by preventing the loading of a bunch of unnecessary stuff on a webpage.
But after updating Ghostery recently on a Mac, I noticed a serious performance hit to Safari browsing, and suddenly Safari was working at a snails pace. It was as if my speedy M1 Mac with the latest macOS Monterey build had become an old beige box Pentium II struggling to run a bloated Internet Explorer on Windows XP – the CPU was pegged and grinding to a halt when any webpage was loading, the beachball from unresponsive pages, and searching the web was suddenly uselessly slow – something was clearly amiss.

The culprit? Some new settings in Ghostery that appeared after updating the extension. Turning those off immediately returned performance to where it should be in Safari with a functional content blocker.
