pref("privacy.trackingprotection.storagerestriction.enabled", false); - in FF63 they 1st renamed it to privacy.3rdpartystorage.enabled but now removed the pref again and merged it with network.cookie.cookieBehavior. Best to ignore for FF62 IMO, because otherwise we have it in the user.js for 1 version and then have to move it to 9999.
We can list it at the top of this issue "for visibility" for those who want to try it. (but I'm not sure if it needs TP enabled or if it's even fully ready yet in FF62)
pref("extensions.webextensions.ExtensionStorageIDB.enabled", false); - there have already been a couple of issues identified with this (+ fixed in latest FF63) and it's best to wait until they enable it by default IMO. I suggest we move it to "ignore"

earthlng · 2018-08-14T18:15:33Z

users who block all cookies can't use TP

You can use TP and block all cookies just fine AFAIK. ATM there are 2 kinds of TP, active and passive. Active TP will completely block requests (which could theoretically also try to set a cookie) while passive TP will just prevent the cookie from being set. At least that's how I think it works.

Seems like a nice option for people who don't want to allow everything (0=allow all cookies and site data) but for whom 1st-party-only breaks too many of their favorite sites.
Maybe one day mozilla will make it the new default value instead of 0.

earthlng · 2018-08-15T08:21:45Z

network.cookie.cookieBehavior=0 - you block all cookies

0 = you ALLOW all cookies

FF63 will have a new option available cookieBehavior=4 = allow all except from tracking resources

earthlng · 2018-08-20T14:33:09Z

They'll set fallback-limit pref to TLS 1.3 by default for Firefox 62 and IMO we can just remove that pref from the user.js because it's not necessary to enforce the default. plus: "We're on the road to remove that code"

earthlng · 2018-08-31T16:31:29Z

moved from new to ignore -> new:

all the activity-stream shit since it's still possible to delete the system addon. FF63+ will have it built-in and we'll deal with it then
pref("browser.security.newcerterrorpage.enabled", false); - wait until they enable it by default
pref("browser.tabs.multiselect", false); - not privacy/security related
pref("devtools.inspector.fonthighlighter.enabled", false);
pref("devtools.inspector.three-pane-first-run", true);
pref("dom.webcomponents.shadowdom.report_usage", false);
probably nightly-only. We'll see it in the diffs if they ever change it to true in beta or release
pref("extensions.webextensions.ExtensionStorageIDB.enabled", false); - see my comment
pref("privacy.trackingprotection.storagerestriction.enabled", false); - see my comment

moved from changed to ignore -> changed:

pref("apz.android.chrome_fling_physics.enabled", true); // prev: false - Android. IDGAF
pref("dom.ipc.plugins.sandbox-level.flash", 3); // prev: 2
Flash. IDGAF. higher sandbox-level is always welcome but we don't need to enforce it or anything
pref("dom.registerContentHandler.enabled", false); // prev: true
navigator.registerContentHandler() has been removed 👍
pref("dom.registerProtocolHandler.insecure.enabled", false); // prev: true
navigator.registerProtocolHandler() can no longer be used on insecure sites 👍
pref("network.http.throttle.version", 1); // prev: 2
pref("security.pki.name_matching_mode", 3); // prev: 1
more restrictive hostname matching in TLS certificates 👍

some of the remaining changed prefs might be beta-only, let's wait until 62-release is out

earthlng · 2018-09-05T13:30:35Z

62.0 changes since 62b20

new

pref("browser.newtabpage.activity-stream.improvesearch.topSiteSearchShortcuts", false); // true in 62b20
~~pref("services.sync.engine.bookmarks.validation.enabled", true);~~
~~pref("services.sync.engine.passwords.validation.enabled", true);~~

... This feature is currently limited to Windows, though it may be extended to macOS later (in bug 1326181).

Firefox will automatically restore your tabs after Windows OS reboot. To disable this feature, set the "toolkit.winRegisterApplicationRestart" pref to false.

browser.sessionstore.resuming_after_os_restart is used internally and toggled back and forth automatically -> moved to ignore

also Content loads and runs before user has logged in but it might be a Windows 10 problem only

dom.registerContentHandler.enabled & dom.registerProtocolHandler.insecure.enabled .. both previously true - shouldn't we add these for ESR60 users? or were they also flipped there?

no they were not flipped in ESR60.
dom.registerContentHandler.enabled isn't listed under "Privacy & Security" in Firefox 62 Site Compatibility so IDK if we need that.
But ESR60 users might also want user_pref("layout.css.moz-document.content.enabled", false); "since it could be used by attackers for CSS injection to steal private data in the URL of third-party sites."

can't find the two pdfjs.*ModeOnLoad on DXR

https://dxr.mozilla.org/mozilla-beta/search?q=scrollModeOnLoad
https://dxr.mozilla.org/mozilla-beta/search?q=spreadModeOnLoad

looks like DXR is lacking behind a bit and beta hasn't been merged to release etc.

earthlng · 2018-09-08T14:01:15Z

I'd say we don't add stuff just for ESR60 users. They know they won't get non-critical updates.
There was a good reason to stick with ESR52 for the legacy extension support but IDK why anyone would choose ESR60 over release, beta or nightly. And this user.js was always made for Release anyway.
The rest under new and changed can be ignored as well IMO.
Add toolkit.winRegisterApplicationRestart if you want and then we can close this

earthlng · 2018-09-08T16:05:52Z

well both the register*Handler APIs are behind prompts anyway, fe see https://mdn.mozillademos.org/files/9683/protocolregister.png and the problem with disabling the moz-document css rule in ESR60 is that the exception which prevents most or all of the breakage landed in 61 and wasn't backported.

earthlng · 2018-09-08T16:36:37Z

No we don't need to do anything, no warning no cleanup no nothing. ESR users can continue to use the latest master and just activate the ESR60 deprecated part with the one-char switch.
There's probably not a lot of stuff that we'll change in terms of existing prefs anyway, mostly we'll add new prefs that won't exist in ESR or remove old prefs which they can re-enable in 9999

#463 (comment)

lets add toolkit.winRegisterApplicationRestart somewhere and set it to false and active. It could be pretty annoying when content loads and runs before user has logged in

earthlng · 2018-09-08T17:00:19Z

^^ that's because of pref("browser.startup.blankWindow", true); // prev: false. It has that problem when RFP is enabled

earthlng · 2018-09-08T17:48:04Z

blankWindow: https://bugzilla.mozilla.org/show_bug.cgi?id=1448423

toolkit.winRegisterApplicationRestart: definitely not 0001. /*** 0100: STARTUP ***/ or maybe under MISC, IDK.

earthlng · 2018-09-08T17:53:43Z

"disable automatically restoring your Firefox session after OS restarts (FF61.0.2+)"
"As of FF62 it's Windows-only but support for MacOS is also planned"

earthlng · 2018-09-09T12:34:50Z

blankWindow: once bug 1448423 gets fixed we can remove the pref again - add the link for easy reference?

winRegisterApplicationRestart:

whats with the 61.0.2+ - did it land in a dot release?

https://www.mozilla.org/en-US/firefox/61.0.2/releasenotes/

Adds support for automatically restoring your Firefox session after Windows restarts. Currently, this feature is not enabled by default for most users, but will be gradually enabled over the coming weeks.

(61.0.2+) or (FF62+) - whatever you prefer is fine
