From fdc9db9a084d6ef4f058d01ff8e204054f485591 Mon Sep 17 00:00:00 2001 From: Thorin-Oakenpants Date: Sun, 26 May 2019 08:43:12 +0000 Subject: [PATCH] 1600s revamp - no need to enforce defaults (except the second cross-origin) = less items in prefs and about:support - simplify header info - add in that you need an extension for real control: i.e for most people, e.g I use uMatrix and have never can to whitelist anything. Kolanich has been on settings of 2 for years and only found one broken site: these are anecdotal and don;t reflect the real world: which is why the settings are pretty relaxed - move the broken info out of header and onto the pref in a setup tag - reference: https://github.com/ghacksuserjs/ghacks-user.js/issues/716#issuecomment-488527274 - thanks Kolanich and :cat2: --- user.js | 36 +++++++++++++++++++----------------- 1 file changed, 19 insertions(+), 17 deletions(-) diff --git a/user.js b/user.js index b3eeb668..2da4f387 100644 --- a/user.js +++ b/user.js @@ -826,45 +826,47 @@ user_pref("gfx.font_rendering.graphite.enabled", false); // user_pref("font.system.whitelist", ""); // [HIDDEN PREF] /*** [SECTION 1600]: HEADERS / REFERERS - Only *cross domain* referers need controlling and XOriginPolicy (1603) is perfect for that.
