With Safari 13 my favorite Mac ad and tracker blocker uBlock Origin, along with a few other extensions, no longer work. Because of this, I have switched to Firefox as my main browser. That said there will still be times when I will want to use Safari and will want an ad and tracker blocker.
I tried Ghostery Lite but I had two issues with it. It doesn’t block YouTube ads and I didn’t like the way it handles space left behind by blocked ads.
For now, I’ve settled on Wipr. Wipr blocks all ads, trackers, cryptocurrency miners, EU cookie and GDPR notices, and other annoyances. I also switched to Wipr for Safari on my iPhone and iPad in place of BlockBear. BlockerBear was working fine but for consistency, I switched to Wipr.
