The owners of MacBook Pro models with ProMotion displays should be interested in the new version of Firefox that promises improved browsing performance on displays with higher refresh rates.
Apple's new MacBook Pro models with M1 Pro and M1 Max chips feature Liquid Retina XDR displays with ProMotion technology for adaptive refresh rates ranging from 24hertz to 120hertz.
When viewing a static webpage that doesn't require a high refresh rate, the MacBook Pro's display adopts the lower refresh rate to preserve battery life, but when gaming, scrolling, or doing other activities where a higher refresh rate will result in smooth content, the higher frame rates will kick
The 14-inch and 16-inch Macs with ProMotion stand to benefit from the latest Firefox 103 update, as it brings improved performance on displays capable of refresh rates upwards of 120hertz.
After Apple launched 14-inch and 16-inch MacBook Pro models with Apple Silicon last October, many users began reporting issues with stutters and scrolling in Apple's browser.
Apple has never confirmed that ProMotion is functional in its native browser for Mac, despite some users reporting smooth scrolling and performance after they upgraded to macOS Monterey 12.2. It is possible to use a browser that is capable of running ProMotion at full tilt, even if you are unconvinced that optimal refresh rates are happening inSafari.
According to the release notes, Firefox 103 also offers improved responsiveness on macOS during periods of highCPU load, which it achieved by changing to a modern lockAPI.
The ability to change the subtitles size directly from within a Picture-in-Picture window is one of the new features in this update.
There are a number of bugs and security vulnerabilities that have been fixed in other changes. The full list of changes can be found on the website of the Mozilla company.
