+## `prefetch.json`
+
+Enables prefetching. Will make sites very speedy, but decreases privacy and may
+conflict with uBlock Origin. However AdNauseam is already clicking those ads, so
+maybe it's not that big of an issue.
+
+## `profilemanager.json`
+
+Forces the profile screen even with only one profile. I love the feature in Firefox
+and want to see it here too, now that I accidentally noticed it.
