 Most repos have niche privacy and security concerns with little regard for speed, annoyances, or mainstream use. Betterfox was 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). For instance, features like WebGL and DRM are still enabled, and you won't find a setting like `privacy.resistFingerprinting` mentioned here<sup>^[*why?*](https://old.reddit.com/r/firefox/comments/wuqpgi/are_there_any_aboutconfig_tweaks_to_get_smooth/ile3whx/?context=3)</sup>. And while Betterfox is designed to set-and-forget, it contains plenty of options for those who like to tinker.
