We have developed a DNS filter extension that works for most applications, but it does not receive all DNS queries.
In particular, if we have our extension installed and enabled, we see Safari browsing cause local DNS servers to be used instead of going through our extension.
What is the logic for how DNS servers vs. extensions are chosen to resolve DNS queries?

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
DNR rules redirecting to an extension path lead to an error page: “Safari can’t open the page. The error is: “The operation couldn’t be completed. (NSURLErrorDomain error -1008.)” (NSURLErrorDomain:-1,008).”
Here is a demo extension that replicates the bug: https://github.com/lenacohen/Safari-Test-Extensions/tree/main/dnr-extension-path-redirect
This is an example of a redirect rule that leads to an error page instead of the extension path page:
chrome.declarativeNetRequest.updateDynamicRules({addRules: [
{
id: 2,
priority: 1,
action: {
type: "redirect",
redirect: {
extensionPath: "/web_accessible_resources/test_redirect.html"
}
},
condition: {
urlFilter: "||washingtonpost.com^",
resourceTypes: [
"main_frame"
]
}
}
]});
The extension path is included in web_accessible_resources in the extension manifest:
"web_accessible_resources": [{
"resources": [
"web_accessible_resources/test_redirect.html"
],
I also submitted a bug report on Apple's Feedback Assistant: FB16607632
I want to write an app, that lets users restore all oben windows and tabs from any given point in a TimeMachine backup. The store location seems to have changed. In earlier versions it was possible to restore the open windows and tabs by retrieving
/Users/[UserName]/Library/Containers/com.apple.Safari/Data/Library/Safari/SafariTabs.db
…/SafariTabs.db-shm
…/SafariTabs.db-wal
As of 18.3 this doesn’t work any more, even though these files get updated with the use of Safari
What else would I need to retrieve from a back up disk?
Thank you very much for any hints!
My app is a Safari extension. When trying to validate the app, I get the following error:
App sandbox not enabled. The following executables must include the "com.apple.security.app-sandbox" entitlement with a Boolean value of true in the entitlements property list: [( "app.rango.Rango.pkg/Payload/Rango for Safari.app/Contents/MacOS/Rango for Safari" )] Refer to App Sandbox page at https://developer.apple.com/documentation/security/app_sandbox for more information on sandboxing your app.
I don't know why this is happening. I have app sandbox enabled in both the app and the extension target. I have both entitlement files. When executing codesign -d --entitlements :- /path/to/binary I get the following:
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "https://www.apple.com/DTDs/PropertyList-1.0.dtd"><plist version="1.0"><dict><key>com.apple.security.app-sandbox</key><true/><key>com.apple.security.files.user-selected.read-only</key><true/><key>com.apple.security.get-task-allow</key><true/><key>com.apple.security.network.client</key><true/></dict></plist>
If I check on Activity Monitor, on the sandbox column it shows true. I have no idea why I keep getting this error when all indicates that the app is actually sandboxed.
I have a Safari App Extension which allows users to switch between last open tabs with a shortcut option+tab in the same way it's possible to switch between last open apps with command+tab.
Here is how i do it:
I inject a content script on all websites which has the only thing – key listener for option+tab presses.
When a user presses option+tab, that keyboard listener detects it and sends a message to the Safari Handler.
Then Safari Handler sends a message to the containing app and it shows a panel with last open tabs.
This approach has a problem: it shows a message to a user in settings: "Can read sensitive info from web pages, including passwords..."
Which is bad, because in reality i don't read passwords.
If i remove SFSafariContentScript key in the Safari App Extension target's Info.plist, then this message about reading sensitive data disappears, but then i loose the ability to open the tabs panel.
How can I open my app window with a shortcut without frightening a user?
It's possible to listen to global key presses, but that would require a user to grant the app permissions of Accessibility (Privacy & Security) in macOS system settings, which also sounds shady.
I know an app which does not require an Accessibility permission: https://apps.apple.com/ua/app/tabback-lite/id6469582909 and at the same time it does not tell a user about reading sensitive data in the extension settings.
Here is my app: https://apps.apple.com/ua/app/tab-finder/id6741719894 It's open-source: https://github.com/kopyl/safari-tab-switcher

Recently we started noticing in Safari v18.2 browser an unexpected useragent set for https://www.espn.com pages like -
"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/110.0.0.0 Safari/537.36" (recognized as Chrome by most UA detection logic) and breaks our video playback in some scenarios.
When digging into this we came across site specific quirks and the "Disable site-specific hacks" setting which fixed the playback functionality and set a more expected UA - "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/18.2 Safari/605.1.15".
Is the unexpected UA being set somewhere in Safari/Webkit? Can this be removed so site functionality works without needing to find the "Disable site-specific hacks" setting?
