-## Made for everyday browsing
-**A secure, blazing fast browsing experience. Without breakage.**
-
-Betterfox is an opinionated preference list inspired by the [law of diminishing returns](https://pmctraining.com/site/wp-content/uploads/2018/04/Law-of-Diminishing-Returns-CHART.png) and the [minimum effective dose](https://medium.com/the-mission/less-is-more-the-minimum-effective-dose-e6d56625931e).
-
-## Simple goals
-1) **Minimalism:** get what isn't needed out of the way
-2) **Efficiency:** unleash Firefox's ability to be fast and performant
-3) **Privacy:** protect your data without causing site breakage
-
-## Simple configs
