Soon after releasing 1Blocker in 2015 and adding more features (Whitelist, Hide Elements, Make HTTPS, iCloud sync, etc.) and extending our rule sets, we found out that we are about to hit the limit of total number of rules allowed for a Safari content blocker extension. Apple set the limit at 50K rules, and we were already at 49K. […]

The only solution to that problem is to create multiple extensions within 1Blocker that independently manage blocking in Safari. However, that requires rewriting the app to handle all these new extensions.

This looks like it’s going to be a great upgrade from the current version of 1Blocker, which I’ve been using since Ben Brooks declared it as the best content blocker shortly after iOS 9’s release. I wish the team would have spent a little bit more time on the icon, but let’s be honest, it’s just going to get tucked away inside a folder anyway.
