Apple's WebKit blog detailed Safari 27.0's developer features, headlined by a new Safari MCP server that lets AI coding agents like Claude Code or Codex control the browser to inspect DOM elements, network requests, screenshots, and console output. Developers enable it through Safari's Developer settings after turning on features for web developers, and Apple says the server runs locally without sending data externally.
Alongside its new macOS 27 Golden Gate release, Apple has pushed out macOS Tahoe 26.7 and macOS Sequoia 15.8 as updates for users who haven't moved to the newest OS. Apple describes both as containing important security fixes recommended for all users, though it has not yet published detailed release notes on its security page.
Apple's WebKit team has opened a call for proposals for Interop 2027, the next round of the annual cross-browser project run with Google, Microsoft, Mozilla, Bocoup, and Igalia.

Mozilla has launched a native Ad Blocker feature for Firefox on iOS that blocks many third-party ads and ad-related trackers before they load. The feature relies on Apple's WebKit Content Blocker technology and the EasyList filter list, and is disabled by default, requiring users to enable it through Settings > Browsing > Ad Blocker.
Mozilla has officially rolled out a native ad-blocking feature in Firefox for iOS after a brief testing period. Built using Apple's WebKit Content Blocker technology and the EasyList filter, it strips out most third-party ads and trackers before pages load, cutting data usage and cleaning up cluttered sites. The feature is off by default and must be enabled through the browser's settings.
Apple has silently fixed a flaw in iCloud Private Relay that allowed a user's real IP address to leak under three specific conditions, despite the feature being enabled. Security researchers Talal Haj Bakry and Tommy Mysk, who discovered the issue and built a public tool to test for it, confirmed the fix landed in iOS 26.6.1 (and matching updates for other Apple platforms) though Apple did not disclose it in official release notes. The researchers noted the repair appears limited to Safari and was made without them first reporting it to Apple.
