A new setting not mentioned in the release notes: layout.css.prefers-color-scheme.content-override = 1 # An override for prefers-color-scheme for content documents. # # Dark (0), light (1), or system (2). I use it to force webpages to use light theme while having dark browser UI elements (menus, tabs etc).
