![]() Testing conducted by Apple in September 2022 by measuring page load performance of snapshot versions of 10 popular websites under simulated network conditions.Performance will vary based on system configuration, network connection, and other factors. Tested with prerelease Safari 16.1 with WPA2 Wi-Fi network connection. Tested on 13-inch MacBook Pro systems with Apple M2, 8-core CPU, 10-core GPU, 8GB of RAM, and 256GB SSD, as well as a production 1.7GHz quad-core Intel Core i7-based 13-inch MacBook Pro system with Intel Iris Plus 645 graphics, 16GB of RAM, and 2TB SSD, all configured with prerelease macOS Ventura. Testing conducted by Apple in September 2022 using JetStream 2.1, MotionMark 1.2, and Speedometer 2.1 performance benchmarks.Performance will vary based on usage, system configuration, network connection, and other factors. Devices tested with a WPA2 Wi-Fi network connection. Tested with prerelease Safari 16.1 and latest stable versions of Chrome, Microsoft Edge, and Firefox at the time of testing on: 13-inch MacBook Pro systems with Apple M2 and prerelease macOS Ventura, and Intel Core i7-based PC systems with Intel Iris Xe Graphics and Windows 11 Pro iPad Pro 12.9-inch (5th generation) units with prerelease iPadOS 16.1, and Intel Core i7-based PC systems with Intel Iris Xe Graphics and Windows 11 Pro and iPhone 13 Pro Max with prerelease iOS 16.1, and Qualcomm Snapdragon 8 Gen 1-based smartphones with Android 12. Non-persistent background pages are an option for the upcoming Safari 15 on Macs and iPads but will be required on iPhones to save resources, Epskamp-Hunt said. At other times, Safari shuts down its background page to save memory, processor power and battery life. To use them, an extension tells Safari to check for particular actions that will trigger the extension to run. Extensions often perform tasks in invisible "background" tabs that consume computing resources.Īpple's fix is non-persistent background pages, which let Safari run extension code only when needed, Safari engineer Ellie Epskamp-Hunt said in a WWDC talk. Safari on iOS 15 moves its address bar to the bottom of the iPhone screen and shows you when it's running an extension.Īpple/Screenshot by Stephen Shankland/CNETĪt WWDC, Apple introduced a new programming interface that's designed to prevent extensions from draining your battery fast. Now Google, Apple, Mozilla and Microsoft have banded together to try to standardize extensions and make them more secure. Google modernized browser extensions with Chrome using an approach other browser makers generally adopted. The technology has now been embraced by all major browser makers.Īs with Safari for Macs, you'll find and install extensions for mobile Safari using Apple's app store. But the iPhone maker did beat Google, which pioneered the extensions for its Chrome browser. Firefox and Kiwi allow the browsers to be extended with new software when running on Android. Still, developers could have to make some adjustments, such as ensuring their extensions don't look bad with smaller screens, Safari engineer David Quesada said in a WWDC talk.Īpple isn't the first company to roll out mobile extensions. Many Safari extensions built for Mac will work without significant changes. Chrome, Safari, Firefox and Edge join forces to improve browser extensions. ![]()
