It‘s called Track Configuration API found in the iOS 26.0 Public Beta 5. No explanation anywhere on the web Or release notes, it’s not mentioned anywhere. I‘m very interested in new tracking innovations.
And another small thing I‘ve never found out, what is „fingerprint related quirk“ is that an insider joke Or something? I don‘t know it‘s actions.
Thank you for answering

Dears,
We are facing some issue in ios 18.4.1. Recently some of our end users who updated their ios devices to 18.4.1 have experienced random 403 errors in runtime. as per our analysis, We identified that these errors are associated with "CSRF token mismatch".
After successful login, the user's CSRF token is causing issue and it was changed in runtime, this causes the cookie mismatch, and the users is getting 403 errors, and the user session is getting invalid suddenly.
let me know if anyone facing the same issue in ios 18.4.1 and let me know Is there any workaround for this issue.
Thanks.
ios drop file wrong file name
I use the following simple JS code to drag file from the browser to the desktop.
Works perfect on MacOS.
onDragStart(event, ucpView) {
let file = new BrowserFile([this.file.fileContent], this.file.displayName, {
type: 'application/ucp-scenario'
});
const fileURL = URL.createObjectURL(file);
event.dataTransfer.setData("DownloadURL", `application/octet-stream:${file.name}:${fileURL}`);
event.dataTransfer.setData("text/uri-list", fileURL);
}
but on iOS it keeps nameing the file
Text1.txt
Text2.txt
...
and ignores the DownloadURL
whats the best way to get it workng on both OS?

Since the transition to iOS 18.4, we have been having an issue where when loading an m3u8 file specified in the src attribute of a video tag in WKWebView, the ts file is loaded repeatedly.
Are there any good ideas for this?
Also, if there have been any changes to the specifications of WKWebView, we would appreciate it if you could let us know.
Hello all,
I'm building a web application in ASP.NET MVC (.NET Framework 4.7.2), from this web app I need to send push notifications to users. For the ones who are logged in with windows/android, everything works as expected, but I can't manage to get it work on the apple side.
If I use the same methods to subscribe to push notifications, it shows me the popup that asks the user to enable push notifications, and then I get an endpoint like this:
https://web.push.apple.com/QKC1Muic0H7...
It doesn't work using this (taking the part after https://web.push.apple.com/), I keep getting "Bad device token" (trying to send the notification via APNS).
Then I found out that there is another method to register the device from the frontend, and this one should give me the real device token:
window.safari.pushNotification.requestPermission
But this one doesn't show me the popup, it gives me "denied" without a reason.
I'm trying to a test application which is here https://pwa.vctplanner.it, the web push id is web.it.vctplanner, I created a push package downloadable from POST https://pwa.vctplanner.it/api/v2/PushPackages/web.it.vctplanner, and the code from the frontend is this:
function registerSafariPush() {
// Controlla se Safari Push Notifications è disponibile
if (!('safari' in window) || !('pushNotification' in window.safari)) {
console.log("Safari Push Notifications non supportate su questo browser.");
return;
}
// Il tuo Website Push ID registrato su Apple Developer
var websitePushId = "web.it.vctplanner";
// Controlla lo stato della permission
var permissionData = window.safari.pushNotification.permission(websitePushId);
switch (permissionData.permission) {
case 'default': // L'utente non ha ancora deciso
window.safari.pushNotification.requestPermission(
'https://pwa.vctplanner.it', // URL del server che serve il Push Package
websitePushId,
{}, // dati opzionali da inviare al server
function (permission) {
if (permission.permission === 'granted') {
console.log("Notifiche push abilitate!");
sendSubscriptionToServer({ endpoint: permission.deviceToken });
} else {
console.log("Notifiche push non abilitate dall'utente.");
}
}
);
break;
case 'denied': // L'utente ha negato
console.log("Notifiche push negate.");
break;
case 'granted': // L'utente ha già autorizzato
console.log("Notifiche push già autorizzate.");
sendSubscriptionToServer({ endpoint: permissionData.deviceToken });
break;
}
}
Any suggestions of what I'm missing? Is there a complete guide to how generate the push package?
Thank you
Hi!
I'm working on a web extension for Safari and I need to send messages from the containing application to JavaScript. For this I use the method
class func dispatchMessage(
withName messageName: String,
toExtensionWithIdentifier identifier: String,
userInfo: [String : Any]? = nil
) async throws
of the SFSafariApplication class. If the site is opened in Safari in normal mode, everything works as expected. However, if the site is "docked", the messages are not transmitted to this "Web App".
Is it possible to somehow link the container application to the docked website so that messages from the application are received by this "Web App"?
That you.
I can open an app (e.g. tiktok) from a website of mine by using the deeplink “tiktok://open”, if the app is installed on my iphone. What's the deeplink to launch TestFlight? Thanks in advance

A DNR rule with lower priority is being applied before a DNR rule of higher priority on Safari. Specifically, a low-priority DNR block rule that matches a request is being applied before a high-priority DNR redirect rule that matches the same request, preventing the redirect from occurring. The only way to get the high-priority redirect rule to occur is to remove the DNR block rule. This does not occur on other browsers.
I have already submitted a Feedback Assistant report about this bug: FB16535579
How to reproduce:
Create/install a web extension on Safari with the declarativeNetRequest and declarativeNetRequestWithHostAccess permissions
Open the Web Extension Background Content console and add a redirect rule with a high priority number. For example:
await chrome.declarativeNetRequest.updateDynamicRules({addRules: [
{id: 5000, condition: {urlFilter: "||www.google-analytics.com*/ga.js", resourceTypes: ["script"], domainType: "thirdParty"}, priority: 80, action: {type: "redirect", redirect: {url: “http://www.apple.com/”}}}
]})
Add a block rule of lower priority for the same urlFilter:
await chrome.declarativeNetRequest.updateDynamicRules({addRules: [
{id: 5001, condition: {urlFilter: "||www.google-analytics.com^", domainType: "thirdParty"}, priority: 1, action: {type: "block"}}
]})
Visit https://efforg.github.io/privacybadger-test-fixtures/html/ga_surrogate.html
Check the network tab and see that neither a request to Google Analytics nor apple.com appear. This means that the request to Google Analytics was blocked instead of being / before being redirected
Remove the block rule:
await chrome.declarativeNetRequest.updateDynamicRules({removeRuleIds: [5001]})
Reload https://efforg.github.io/privacybadger-test-fixtures/html/ga_surrogate.html.
Check the network tab and confirm that there is a request to apple.com, showing that the redirect rule is only applied if the lower-priority block rule is removed. The priority of the DNR rules should handle this without having to remove a DNR rule.
I have confirmed that the incorrect application of DNR rule priority happens on other top level domains, with other urlFilters, and with other redirect URLs. I confirmed that this is happening while I’ve granted my extension permissions on all websites.

WebAuthn can be used in Safari, but when using it with WKWebView, you need to set the default browser definition (com.apple.developer.web-browser). Is this correct?
Also, is it possible that the terms of use will change or that it will no longer be available in WKWebView in the future?

Area: WebKit (Safari)
Description:
I am reporting an issue where our application's core functionality is being broken by Safari's Intelligent Tracking Prevention (ITP).
ITP's "Link Tracking Protection" feature automatically strips specific query parameters from URLs. We understand this is an intentional privacy feature. However, our application requires these query parameters to carry essential, non-tracking data, such as authentication tokens or specific app-state information to function correctly.
When a user navigates to our site, Safari strips these parameters, this means our client-side application never receives the necessary data, which breaks core features and leads to a failed user experience. This is a significant issue for our application as it prevents users from accessing their content.
We are seeking guidance on how to resolve this.
Questions for Apple:
Is there a recommended way to identify and flag essential, non-tracking query parameters so that Safari's ITP does not strip them?
Our parameters are critical for app functionality, not for third-party tracking. What is the recommended best practice for building web applications that rely on URL parameters while adhering to ITP's privacy-first model?
We want to ensure our application is compatible with modern browser privacy features without compromising functionality.
Could you provide a detailed explanation of what criteria ITP uses to decide which parameters to strip? Understanding the underlying logic would help us restructure our URLs to avoid this issue.

We are experiencing a problem that seems to be caused by a specification changes for Safari.
We would like to discuss how to solve this problem.
Sample JavaScript:
<html>
<head>
<script>
function jumpPage(code) {
document.main.code.value = code;
win1=window.open("","win1","toolbar=no,resizable=yes,menubar=no,scrollbars=yes,status=yes,left=0,top=0");
win1.resizeTo(width=screen.availWidth,height=screen.availHeight);
document.main.action="details";
document.main.target="win1";
document.main.submit();
}
</script>
</head>
<body>
<form name="main" method="post" action="" target="">
<a href="javascript:jumpPage('001')">details</a>
<input type="hidden" name="code" value="">
</body>
</html>
This JavaScript performs the following actions when a link is clicked.
Open a window using window.open in JavaScript
Submit the above opened window by post method to the target in JavaScript.
When this operation is performed, the process in (2) could submit to the
target page with “POST” method before iOS18.1, but
will transition to the page with“GET”method from iOS18.2 onward.
All protocols are http.
This problem does not occur if the URL is specified as an IP address, but it does occur if the host name is specified as.
Please let me know how to use with“POST”method as in iOS 18.2 or earlier.
Best regards,

Hi everyone, i'm running into a problem with my personal domain being flagged as 'deceptive website' in safari, and i can't figure out how to fix it
Domain: neon0404.space
This is just my personal domain - i use it for adguard home, vaultwarden, some test stuff, sometimes small web tools for friends or family
Nothing illegal or malicious has ever been hosted there
On july 6, i launched a very simple web utility for a friend
when he opened it on ios safari, he got the red 'deceptive website warning'
I checked this on other different devices - all got the same warning
The next day (july 7) i submitted a review request via websitereview.apple.com, but got no reply
I did some digging and found that safari safe browsing daemon pulls data from google safe browsing, tencent safe browsing, and some apple's internal lists
So, going one-by-one
https://transparencyreport.google.com/safe-browsing/search showed up that domain is flagged for something shady
Signed up in google search console and saw my domain was flagged for 'malware links' (with no related urls listed), so looked like a false positive
I audited everything related to this domain on august 5 - nothing suspicious
Next day i requested a review in Google Search Console, just next day Google confirmed that everything is ok and removed the flag
So, i thought, maybe this was the key and requested another review via websitereview.apple.com (august 7)
No reply, domain still flagged
While i was waiting, i checked domain in Tencent (https://urlsec.qq.com/check.html) - no issues
Other services like VirusTotal, Norton and Sucuri showed up same result - no issues
I attempted to contact regular support (even though it's not their area of responsibility), but just in case
They, as expected, couldn't do anything
At this point it feels like a dead end, so i'm here
Has anyone been through this before?
Is there any other way to escalate the review process with apple?
Really appreciate any advice, as this domain is personal and linked to my username, which i want to use later
We confirmed a problem at Safari on iPadOS 18.2 or after version.
For confirmation, we made a HTML document (see below HTML1) what include ‘method="POST" target="_blank"’ and tested the form however server received GET method and there is no parameter, server did not receive “id” parameter.
We confirmed that fact in captured packet and log file that on the server.
HTML1:
We also made another HTML document (see below HTML2) what include submit button, but the server received GET method as above.
HTML2:
And we also confirmed that it behaves differently depending on the network environment.
If the form targets a name that does not exist (ex. target=” A12345”), behaves differently http or https.
http:
Safari opened new tag, but the server received GET method. Normally, Safari open new tag and the server receive POST method.
https:
Safari opened new tag, and the server received POST method. It is normally.
If the form targets ‘_blank’, the server received GET method on http or https both.
We think Safari change the method POST to GET and delete parameters.
It is not conformed to the HTML specification if is that true.
We confirmed it was not happened at Safari on iPadOS 17.4, and Windows PC (Edge, Chrome).
The method what the server received is POST.
We find same problem in Apple Support Community (see below URL).
https://discussionsjapan.apple.com/thread/255987615 (Described in Japanese)
Is it a bug in Safari on iPadOS 18.2 or after version?
Do you have plan to fix? Or if fixed the bug, when do you release fixed version.

I have a Safari extension that plays audio via the javascript AudioContext API. It was working fine under iOS 17 and is now broken under iOS 18. It does not play audio at all.
I've tried in both the iOS 18 public beta and the iOS 18.1 developer beta. It is broken in both of them.
I've also created Feedback item FB15170620 which has a url attached to a page I created which demonstrates the issue.
We have written a PAC script that blocklists certain domains and whitelists others. We went to Settings > Network > Wi-Fi (the network we are using), then clicked on Details, and under Proxies, we added the PAC file URL in the Automatic Proxy Configuration section.
We tried hosting the PAC file both on localhost and on a separate HTTP server.
After saving the settings, we tested several URLs. The blocking and allowing behavior works correctly in all browsers except Safari.
Below is the PAC script we are using for your reference.
The script works as expected in browsers other than Safari.
This is how the PAC script URL looks:
http://localhost:31290/proxy.pac
function FindProxyForURL(url, host) {
var blacklist = new Set(["facebook.com", "deepseek.com"]);
var b_list = [...blacklist];
for (let i = 0; i < b_list.length; i++) {
let ele = b_list[i] + "*";
if (shExpMatch(host, ele) || shExpMatch(url, ele)) {
return "PROXY localhost:8086";
}
}
if (isIPBlocked(whitelist_subnet, hostIP)) {
return "PROXY localhost:8087";
}
if (isIPBlocked(blacklist_subnet, hostIP)) {
return "PROXY localhost:8086";
}
return "PROXY localhost:8080";
}
I've been unable to successfully get a webpage to send a message to a Safari web extension, no matter what I try doing.
I've added the following to my manifest.json file, and it's running manifest v3
{
"externally_connectable": {
"matches": [ "*://mywebsite.com/*", "*://localhost:3000/*" ]
}
}
My web page executes the following code snippet. I've tried this both while running my site locally (on localhost) and pushed to production.
let safariExtensionId = "co.companyname.productname.Extension (ABCD1234)"
browser.runtime.sendMessage(safariExtensionId, { greeting: "hello"},
function(response) {
console.log("Received response from background page");
console.log(response.farewell);
}
);
In the Safari web extension's background.js file, I've added the following onMessageExternal listener:
browser.runtime.onMessageExternal.addListener((message, sender, sendResponse) => {
console.log("Received message from the sender.");
console.log(message.greeting);
sendResponse({ farewell: "Goodbye!" });
});
This is directly copied from the instructions in this WWDC video:
https://developer.apple.com/documentation/safariservices/messaging-between-a-webpage-and-your-safari-web-extension
It's also extremely difficult to debug what's happening since the extensions service working frequently does not appear in the Web Extension Background Content menu
Is there something I'm doing wrong, or a bug I'm not aware of?
After updating to iOS 18.4, our web application (with service workers) crashes on devices that accessed it prior to the update. This issue also affects hybrid mobile apps using the same web application; reinstalling the app resolves it by refetching and reinstalling service workers. Debugging is challenging because clearing the cache or reinstalling the app fixes the problem, and no useful error logs are available. Has anyone encountered similar crashes related to service workers after an iOS update and have any insights into the cause?
Hi everyone,
My web application has two services: myapp.com and account.myapp.com.
The first manages all app content, while the latter handles the authentication, with Sign In with Apple included.
The tech stack is mainly composed of React, JS, and Express.
We'd like to allow users to authenticate inside a dialog on some pages of myapp.com.
To avoid replicating stuff from one service to another, we put an iframe inside the dialog to show the authentication standard page from account.myapp.com.
Email and Facebook processes work fine, but we have the following issues with Sign in with Apple:
On desktop, not Safari, a pop-up window opens when you click on the Apple button, and it works as expected.
On desktop Safari, the pop-up window is blocked. We want the native Apple pop-up to show instead of a generic browser new window.
On mobile, nothing happens on click
Obviously, outside the iframe, everything works as expected.
I can't seem to find anything related to an iframe constraint in the Sign in with Apple docs. Is this feasible?
