FF128 release date: Jul. 9th 2024

FF128 release notes
FF128 for developers
FF128 security advisories

140 diffs ( 80 new, 37 gone, 23 different )

FF129+ 1658094 Clearing site preferences on shutdown also clears exceptions for clearing on shutdown
- b498a65
- tested all three site settings clearing methods
- for the record arkenfox has never sanitized site settings (or passwords), but this may now be feasible for some users

new in v128.0:

pref("browser.urlbar.recentsearches.featureGate", true); 1900900 - e0ec4d0 & b1c43d4
FYI
- 0805 pref("browser.urlbar.trending.featureGate", true);
- pref("network.cookie.sameSite.crossSiteIframeSetCheck", true); - sounds good to me, bugzilla access denied
- pref("browser.backup.scheduled.enabled", false);
- hoverPreview
  - pref("browser.tabs.hoverPreview.enabled", false);
  - pref("browser.tabs.hoverPreview.showThumbnails", true);
  - when enabled = true you get the URL on a secondary line and a thumbnail if that is true
- pref("network.proxy.socks5_remote_dns", true); 1741375 sounds good to me
FYI CHIPS + 1865198 META
- pref("network.cookie.CHIPS.enabled", false);
- pref("network.cookie.cookieBehavior.optInPartitioning.pbmode", false);

changed in v128.0:

FYI

pref("privacy.bounceTrackingProtection.enabled", true); // prev: false
- URLs and timestamps are stored in bounce-tracking-protection.sqlite
- these are not sanitized on close: not sure how long lived they are
- this will become part of ETP Strict
- the benefits of bounce tracking protection outweigh touching the disk - if your disk was compromised you have bigger issues to worry about, so this is out of scope for this project

is good privacy protection that leaks browsing history even when user choose to clear it?

Interesting, I haven't read anything related to browsing history leaks but I'll admit I can navigate bugzillas like a cat can swim in the ocean, can you expand more on this issue if you don't mind?

Maryse47 · 2024-07-16T13:32:02Z

Close the browser and open bounce-tracking-protection.sqlite file under your firefox profile with some sqlite explorer - it will contain lists of hosts you were connecting to (with a timestamp).

pref("dom.private-attribution.submission.enabled", true);, in about:preferences#privacy -> Website Advertising Preferences. Turned on without user consent when upgrading to 128 (even ESR).😒

I wonder if disabling this would be another fingerprint point.

sertonix · 2024-07-16T13:57:37Z

Yes it is. I wrote a proof of concept here arkenfox/TZP#319

I hope that this can be fixed though.

sertonix · 2024-07-16T15:07:22Z

It seems like disabling toolkit.telemetry.enabled effectively disables dom.private-attribution.submission.enabled. Can somebody verify this?

https://searchfox.org/mozilla-central/rev/f3e4b33a6122ce63bf81ae8c30cc5ac37458864b/dom/privateattribution/PrivateAttributionService.sys.mjs#267

Vinfall · 2024-07-17T01:33:04Z

It seems like disabling toolkit.telemetry.enabled effectively disables dom.private-attribution.submission.enabled.

Nope, this is incorrect.

I disabled this in user.js and even locked toolkit.telemetry.enabled to false in autoconfig (aka. pref.js), yet upgrading to FF128 still turned on dom.private-attribution.submission.enabled w/o my approval.

I have to explicitly disable dom.private-attribution.submission.enabled in either user-overrides.js or pref.js to turn it off.

Also, it should be locked to false even w/o user.js if it's a stable release according to

user.js/user.js

Lines 144 to 148 in ff5c959

Hi, I just read the news about Privacy-Preserving Attribution in Hackernews.
How do I disable it in user.js? Is setting dom.private-attribution.submission.enabled to false sufficient?

Vinfall · 2024-07-17T02:35:09Z

(kind of #off-topic I guess)

Yes, if you are using this repo, you can also add it to user-overrides.js so it would not be reverted in user.js update (but it's fingerprintable as suggested above):

// not available in user.js v116 yet
user_pref("dom.private-attribution.submission.enabled", false);

If you are not sure about profile location, check about:profiles.

I mean that disabling toolkit.telemetry.enabled disables the private attribution functionality like a master switch. So when toolkit.telemetry.enabled is disabled dom.private-attribution.submission.enabled has no effect besides adding a fingerprint.

I checked the saved data in the browser and it only changed if both dom.private-attribution.submission.enabled and toolkit.telemetry.enabled are enabled.

I get the point now. ~~Originally I thought it was a bug in the code you linked since it does not work like that (judging from UI)~~ 😢. So regarding

It seems like disabling toolkit.telemetry.enabled effectively disables dom.private-attribution.submission.enabled.

In this case, probably. It's just a bit confusing to me since disabling toolkit.telemetry.enabled alone would still leave that option in about:preferences#privacy on while technically it does no harm besides fingerprint.

Thorin-Oakenpants · 2024-07-23T11:57:39Z

@sertonix please stop saying this

The pref privacy.resistFingerprinting.randomDataOnCanvasExtract only reverts RFP canvas to the old pre FF78 result where it will return an all white canvas - so still unusable

here is TZP showing the results. If you click rerun again and again even the random per run tests for getImageData are static

sertonix · 2024-07-23T13:01:19Z

Oh, sorry. What is the correct way to do this?

Thorin-Oakenpants · 2024-07-23T17:32:13Z

What is the correct way to do this?

add a site exception for canvas - https://github.com/arkenfox/user.js/wiki/3.3-Overrides-[To-RFP-or-Not]#-rfp

Browsing data loss when using the new clear history dialog if Firefox is not closed gracefully backported for ESR128.1

Thorin-Oakenpants · 2024-07-24T19:25:11Z

Oh, sorry. What is the correct way to do this?

so here we go, I updated TZP, because it's not really FPP green... once again ... privacy.resistFingerprinting.randomDataOnCanvasExtract = false = RFP white canvas (if RFP is enabled)

maestropss · 2024-08-12T04:55:28Z

Hi guys. Has anyone made user.js for 128 version considering all the changes discussed above? 128ESR will last for almost a year, so making/having user.js for this version is rather useful and valuable.

rusty-snake · 2024-08-12T06:25:54Z

Is this issue open or closed? Is there an open pull request?

Thorin-Oakenpants · 2024-08-12T06:48:56Z

I will do a 128 for ESR users before I do a 129 or higher. TBH I'm almost losing total interest - edit, but I'll make an effort if y'all nice to me
