It looks like the 4th pref in 0501 experiments.activeExperiment was also removed with 1420908

earthlng commented 6 years ago

we can also remove services.blocklist.signing.enforced rather than deprecate it, because it's default true since FF50

^^ sounds like an Ad for VulnDB and the blame is put on Mitre, not mozilla.

In this case, CVE delivered information on 318 vulnerabilities up to seven years late. Compare that to VulnDB, which had information on all of these issues available immediately after disclosure

uplifted all the way back to and including ESR52

earthlng commented 6 years ago

I'd say we force-disable shield.savant.enabled because fuck shield.

I will definitely also disable tab warmup because I don't want FF to start doing something whenever I hover over a background tab with my mouse. But IDK if it's worth adding under 5000.

And lets not forget about this either. The bugzilla for it is still Access Denied. I think this is about a potential proxy bypass and is definitely more severe in TBB than vanilla FF. But since most people will never really need a website (??) to access a UNC path anyway, it shouldn't be a problem if we add it IMHO.

Atavic commented 6 years ago

error is the log level below warn.

Atavic commented 6 years ago

A fresh bugzilla. And it has Critical Priority.

earthlng commented 6 years ago

this is what it looks like in FF60:

1

0102+0103 could use a [SETTING-ESR60].

re: 0102 ...

need to check that those values 0=blank 1=home still exist

they do

work out what is the default is and what it changes to/from when flicking between the options in the new UI

default is 1. In FF61+ it toggles between 1 and 3

0103: I don't really like the "or use an extension". A newtab extension has nothing to do with privacy/security

re: 0104: "I do not think the preload does anything any more" - in FF61+ it's obsolete because it's checked together with browser.newtabpage.enabled and if that's false then so is newtab preloading. But in ESR60 and ESR52 it's slightly different and for that reason I'd say we keep it.

if 0102 is only about previous session then maybe this could be with the other session stuff?

it's about what happens on startup and thus fits perfectly where it is right now, IMO.

ps: I wouldn't mind activating both 0102 and 0103 and setting them to 0 and "about:blank" to make sure that no websites start loading before all extensions are ready.

earthlng commented 6 years ago

some people set a custom url, others use an extension

yeah but most people don't use either and IMHO it should be the people using custom urls or extensions that should set an override and not the other way around. Also, people might not realize that when they have a homepage set and startup set to 1 (default) that the site will start to load before all their extensions are ready.

earthlng commented 6 years ago

wow they really fucked it up big time! what a fucking mess

Let's just keep it simple and fuck all the infos and settings and shit

/* 0102: set a blank startup-, home- and newtab page ***/
user_pref("browser.startup.page", 0); // 0=blank, 1=home, 2=last visited, 3=resume previous session
user_pref("browser.startup.homepage", "about:blank");
user_pref("browser.newtabpage.enabled", false);
user_pref("browser.newtab.preload", false);
earthlng commented 6 years ago

AFAIK tab warmup is not about making connections and stuff. It's about doing the visual parsing and processing of the page, DOM, etc so that it displays faster when you switch to that tab. We don't need to add it because it's probably not a big issue and most people are so performance hungry these days.
