I am currently developing a Chrome, Firefox and Safari web extension, and I am facing a CSP issue on the content script on Safari. The extension I develop has a content script that injects an img tag in the DOM of web pages the user is visiting. That img tag fetches its content at a specific URL. On Chrome and on Firefox, the img tag content fetches the content at the URL with no issue on every web pages, including those that set the CSP header img-src. On Safari, I'm getting the following error on web sites that set the img-src CSP header: Refused to load https://axxlfrmnpq.cloudimg.io/www.macifavantages.fr/wp-content/uploads/2021/06/Garmin-logo.png?func=bound&w=225&h=113 because it does not appear in the img-src directive of the Content Security Policy. Here is the actual CSP img-src header content of the web page where, on Safari, the injected img tag does not load the content at https://axxlfrmnpq.cloudimg.io/www.macifavantages.fr/wp-content/uploads/2021/06/Garmin-logo.png?func=bound&w=225&h=113: Content-Security-Policy: img-src https://secure.adnxs.com https://www.facebook.com https://.garmin.cn 'self' data: .garmin.com .trustarc.com .truste.com https://static.garmincdn.com https://www.google.com https://www.google.co.uk https://prefmgr-cookie.truste-svc.net https://res.cloudinary.com https://res.garmin.com https://.criteo.com https://.doubleclick.net https://www.googleadservices.com https://px.adentifi.com https://rtb.adentifi.com https://.teads.tv https://www.googletagmanager.com https://bat.bing.com https://.yahoo.com https://sync.outbrain.com https://*.google-analytics.com https://stats.g.doubleclick.net https://static.hotjar.com https://script.hotjar.com .akamaihd.net https://.tealiumiq.com https://deploytealium.com https://pixel.mediaiqdigital.com; My question is, is the page CSP blocking the img tag injected in the web page by the extension's content script? If so, is this behavior documented somewhere, or is it a Safari bug? I saw there is a similar post on the forum, but I couldn't find if the issue is a bug or if it's the expected behavior on Safari: https://developer.apple.com/forums/thread/651542?login=true. Thank you very much for your help.

Our app is an enterprise app via MDM. We are experiencing an issue in iPadOS 18.4 when loading an internal HTTPS server via WKWebView in a hybrid iOS app. Our server uses a self-signed certificate but lacks the digitalSignature usage in its Key Usage extension. (Currently we have no chance to change the server's certificate) We override webView:didReceiveAuthenticationChallenge:completionHandler: to trust the certificate: completionHandler(NSURLSessionAuthChallengeUseCredential, credential); This "completionHandler" works in previous 18.3.2 , but not work in 18.4. May I know is there any changes in 18.4 for the https certification? Why this delegate not work? What we can do to ignore this ssl error and get connection? Thanks in advance, look forward for your reply.

I am currently developing an app using WKWebView. In iOS 17, Apple introduced ProxyConfiguration, and I have two questions regarding its usage: Is there a way to use ProxyConfiguration to distinguish between HTTP and HTTPS traffic? I have reviewed the documentation but couldn’t find a clear method for this. As an alternative approach, I am attempting to determine the request scheme within WKWebView and switch proxyConfigurations just before loading the request. My current implementation sends requests to hoge_a by default and switches to hoge_b only for HTTP traffic. 　 if #available(iOS 17.0, *) { if URLString.contains("http:") { webView.configuration.websiteDataStore.proxyConfigurations = [hoge_b] } } webView.load(request) if #available(iOS 17.0, *) { if URLString.contains("http:") { webView.configuration.websiteDataStore.proxyConfigurations = [hoge_a] } } 　 2. Since I modify proxyConfigurations every time webView.load(request) is called, are there any potential issues or concerns with this approach? I would appreciate any insights you may have on either of these questions.

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,

Safari Extension Error: “Non-persistent background content cannot listen to webRequest events.” after macOS 15.4 / Safari 18.4 Update We’re seeing the following error in the Safari Extensions tab after updating to macOS 15.4 and Safari 18.4: “Non-persistent background content cannot listen to webRequest events.” This error did not appear prior to the update, and we haven’t found any official documentation stating that webRequest API is no longer supported in Safari. In our extension (Manifest V3), we are using the webRequest.onHeadersReceived callback to intercept response headers and read updated cookies. While the functionality itself still works as expected. we’re able to access the response headers and this error is now shown in the Extension settings page. We are not seeing this issue in other browsers (Chrome, Firefox) using the same Manifest V3 setup. Is there any plan to deprecate webRequest support in Manifest V3 for Safari? We’d appreciate any clarification or guidance on how to handle this going forward.

What happens if Safari is uninstalled or disabled on iOS? Will SFafariviewcontroller still work? Kind regards

I'm posting a question here as I have encountered an issue while seeking help from engineers in the thread. thread773837 If the "Not Secure Connection Warnings" is enabled in Settings > App > Safari, are HTTP connections not allowed under any circumstances? I also posted a question about NSAllowsLocalNetworking not being applied, and I was informed that ATS (App Transport Security) is not related to SFSafariViewController. If that's the case, what feature causes the error "Safari cannot open the page. Error: Failed to navigate to an HTTP URL with HTTPS-only mode enabled"? I am currently working to resolve this issue.

How can I set it as a formal payment environment if I can make the payment now without any deduction?

Recently, our some customers feedback that their phones can not connect to our site by safari or App, show the error of “Cannot Connect to Host -1004”，all of these problem customers has installed iOS 18.3 beta. Is there anybody meet the same problem?

Howdy, WKWebView feature request: allow Fullscreen API without User Gestures similar to ElectronJS' userGesture: true flag that allows devs to bypass user gesture restriction for Fullscreen API and similar executeJavaScript(code[, userGesture]) https://www.electronjs.org/docs/latest/api/web-contents#contentsexecutejavascriptcode-usergesture afaik this is allowed because of a fairly recent update to Chromium that also allows users to give Fullscreen API permissions per domain https://chromeos.dev/en/posts/using-the-fullscreen-api-without-gestures Would be greatly useful for a use case in my cross-platform app, so I can avoid rewriting all platforms to use Chromium Thanks

Hi all, I'm developing an application that uses WKWebView to display a web application which I augment with iOS native utilities such as Speech to Text and IAP. The application also uses Service workers, so we define AppBound Domains in the info.plist file. Everything works for this, but when we deploy on a device the application will crash and say we need these entitlements com.apple.developer.web-browser-engine.networking, com.apple.developer.web-browser-engine.rendering, com.apple.developer.web-browser-engine.webcontent, com.apple.runningboard.assertions.webkit From what I can see, we do need all of them. However Apple suggest submitting a request to be an Altnerative Browser (https://developer.apple.com/support/alternative-browser-engines) This is not appropriate for the application in my view since one requirement of being an alternative browser is that you don't modify the resources on the web site - we of course do since we inject javascript in order to bridge between iOS and the contents of the webview. How are people navigating this issue? I assumed it would be common given the use of Tauri etc. to build similar types of applications, but I don't see much about it. Thank you!

Upon upgrading to 18.3 safari now says no connection cleared cookies and data. Disabled all extensions and all von and security anyone else having this issue

This is a rare occurrence on our site, having only detected 4 instances of it over the past few weeks, where 10s of thousands of transactions have occurred successfully. We only call the following PaymentRequest API onClick from the <apple-pay-button>: async function startApplePay(merchantIdentifier, amount) { ... try { const request = new PaymentRequest([ applePayMethod ], paymentDetails); ... catch (e) { // cancel, just stay here if (e.name === "AbortError") { if (consoleLog) console.log("Payment canceled", e); logServer("INFO", "Payment canceled"); } else { handleError("Error caught: " + e.name + ", " + e.cause + ", " + e.message); } } Where the "handleError" else case is what gets triggered: Error caught: SecurityError, undefined, show() must be triggered by user activation. All 4 instances have been from iPads, but with that small of a sample size, we can't tell whether that's relevant or coincidence. Different iOS versions, but looks like same Safari version. Here are the 4 User Agents we've seen thus far: Mozilla/5.0 (iPad; CPU OS 18_2_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) GSA/352.0.715618234 Mobile/15E148 Safari/604.1 Mozilla/5.0 (iPad; CPU OS 17_6_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) GSA/352.0.715618234 Mobile/15E148 Safari/604.1 Mozilla/5.0 (iPad; CPU OS 18_3_0 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) CriOS/133.0.6943.33 Mobile/15E148 Safari/604.1 Mozilla/5.0 (iPad; CPU OS 18_2_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) CriOS/133.0.6943.33 Mobile/15E148 Safari/604.1

Our service includes the Apple web login feature to support "Sign in with Apple" on iOS 12.

I am trying to build and run a Safari Web Extension from Xcode and I have enabled "Allow unsigned extensions" in Safari settings. However, I see the below pop up: And, if click on the "Quit and Open Safari Extensions Preferences..." button, the project stops running on Xcode and nothing happens. What can be the issue? The extension works and runs fine if I get it from the Mac App Store and this only happens when running from Xcode. I even tried completely uninstalling the mac app store version and still facing the same issue.

Hello, following problems described here: https://developer.apple.com/forums/thread/765272 Last version of Safari apparently corrected previous bugs, however we encountered another problem. Right now Safari uses autocomplete feature of some kind (Siri suggested websites/Top hit) which triggers blocking while writing the name of the website. Probably somehow loads website in the background. Problem is, that this behavior is impossible to debug, because this autocomplete doesn't work, while the browser console is open. We are using content script for blocking. Please advise. Thanks very much

Hi all, I need to detect if my web application (pure HTML / Javascript) is opened from: Safari from a Mac Safari from an iPad but by asking for the desktop version I tried to check for many properties (including the navigator.useragent) but no difference were visible. Anyone could help me? Thank you

We seem to be having an issue with a webservice here which is used within our network and IOS Safari. For the service to work , we need to access it with an unencrypted HTTP API call, which acts as a trigger. The server does not respond to HTTPS requests. (the HTTP API call does not contain any data that is privacy sensitive or that can be abused) Since recently the service does not seem to work anymore properly, but this only happens with Safari and IOS. With all other browsers the service is still working normally, only with Safarai it fails. No matter what I do in the settings of the phone, the Safar browser seems to stop immediately after the HTTP request. What is going on here ?? The issue seems to occur only when you don't have an iCloud+ account. With an iCloud+ account I get the same issue when you switch Apple Private Relay on, but that make sense. When I have Apple Private Relay switched off, there is no issue.

When i use adjust redirect: https://app.adjust.com/xxxxxx?label=xxxxxx&redirect=http%3A%2F%2Fwww.testingmcafeesites.com%2Ftestcat_bu.html It open 2 links: https://Fwww.testingmcafeesites.com then http://www.testingmcafeesites.com/testcat_bu.html And in my app use redirect link for open a web page. But content in domain url like https://www.testingmcafeesites.com/ not be set. So it talke long time often 1 minute for finish request in first link. It hapen only in ios 18 i tested in ios 17 and ios 16 it open one link only.
