1848899 - Remove widget.non-native-theme.enabled pref

Status: RESOLVED FIXED

(Core :: Widget, task)

Description

[Gregory Pappas [:gregp]]

Non-native theming of widgets in content has been enabled by default for about 2 years now (bug 1697053). Should be safe to remove this pref now

One benefit of doing this is that it will be harder to accidentally turn off win32k lockdown

Emilio, do you have any concerns about this?

Comment 3

[Thorin [:thorin]]

as long as other prefs don't affect it, because it's also a fingerprint protection

[Emilio Cobos Álvarez (:emilio)]

Yeah, I guess it might be useful to test the native theme on content, but given we already render most of the stuff using the non-native theme I'm fine just removing it.

This came up again in https://phabricator.services.mozilla.com/D207442, probably a good thing to remove it.
