Browser privacy update

In the latest version of http://PrivacyTests.org (Issue 86), we are seeing impressive progress in privacy protections in Safari Private Windows and from Samsung Internet Browser.

  1. Safari Private Windows on Desktop are now protecting against leaks of users' screen size and window position, which can otherwise be used to fingerprint you as you browse the web with a number of other browsers:

  1. Safari Private Windows on Desktop are now also preventing the leak of unencrypted DNS queries. The latest test results show that when you visit a website in a Safari Private Window, the name of the website isn't leaked when the browser looks up the website's IP address.

  1. For the first time, Samsung Internet Browser for Android is now passing nearly all State Partitioning tests. This means it's much harder for a web tracker to "tag" the browser to follow you around the web. (Now the only remaining tested browser on any platform that is still failing most State Partitioning tests is
    DuckDuckGo browser for Android, although it is blocking third-party cookies, which is a good start!)

Congratulations to the teams who deployed these new protections! Let's hope that Safari brings their new privacy protections to normal windows as well, that Samsung fixes the remaining State Partitioning leaks, and that DuckDuckGo finds a way to deploy State Partitioning protections on Android.

We'll keep monitoring browsers for their privacy improvements! โœ…โŒ

Trying to figure out why I'm not getting a preview image in the above post.

@element Fair enough! But given that other feeds have posts with previews I should figure out if I'm doing it correctly.

Browser Privacy Update (a thread)

In the latest version of http://PrivacyTests.org , we can see progress in privacy protections: Safari 17.2 has partitioned the Blob API, joining Brave and Firefox-based browsers. Now only Chrome and some Chrome-derived browsers are still leaking data through the Blob API:

In addition, Safari Private Windows are blocking tracking query parameters and protecting users against the leak of their screen resolution and window position:

Browser Privacy Progress Update

In the latest version of http://PrivacyTests.org (Issue 77), we see that Vivaldi desktop has now adopted substantial State Partitioning protections, joining all other desktop browsers in protecting users against cross-site data leaks. Congratulations to the Vivaldi team for making this important privacy feature available to their users! A thread ๐Ÿงต:

By providing comprehensive State Partitioning, a browser makes it harder for you to be tracked as you browse the web. For the first time, all desktop browsers tested are passing most of the state partitioning tests. Note the sea of green!

Google has announced they'll kill third-party cookies ๐Ÿช in 2024, but despite what it seems, remember that this is only because they have come up with a new way to track users. ๐Ÿ™„

We talked about this on our blog a while ago, and we're well prepared. At Vivaldi we've campaigned against tracking for years, and this won't be any different.

PS. Old but timely pic!

@Vivaldi It's good that you have disabled the Topics API, but will you block third-party cookie tracking now or will you wait for Chrome to do it first?

@Apan I think it may only work when DoH has been enabled. I am working on a more extensive test of this.

Browser privacy update

More good news! In the latest issue of http://PrivacyTests.org, we can see that Opera on Desktop has now shipped the State Partitioning protections recently developed and deployed by the Chromium team.

These State Partitioning protections keep data from leaking between websites. That makes it harder for trackers to gather your browsing history.

privacytests,
@privacytests@mastodon.social avatar

Vivaldi Desktop has not yet shipped these protections in Release, but we do see in our testing of preview builds (http://PrivacyTests.org/nightly) that the protections are enabled in Vivaldi Snapshot, so it seems likely they will be shipped in Release in the near future.

On Android, we see major progress as well (http://PrivacyTests.org/android)! For the first time, we see Chrome and Edge have shipped the same State Partitioning protections! DuckDuckGo, Opera, Vivaldi, and Yandex have not yet done so, however.
