- On the platform Windows The ability to use a two-finger swipe gesture on the touchpad to the right or left to navigate through your browsing history has been implemented.
- Compatibility with the User Timing Level 3 specification is provided, which defines a programming interface for developers to measure the performance of their web applications. In the new version, the performance.mark and performance.measure methods have additional arguments for setting your own start/end time, duration, and attached data.
- The array.includes and array.indexOf methods were optimized using SIMD instructions, which made it possible to double the search performance in large lists.
- В Linux The likelihood of Firefox running out of available memory has been reduced, and its performance when running low on memory has been improved.
- The stability of the platform has been significantly improved. Windows in conditions of insufficient memory in the system.
- Added the OffscreenCanvas API, which allows drawing canvas elements to a buffer in a separate thread, regardless of the DOM. OffscreenCanvas implements work in Window and Web Worker contexts, and also provides support for fonts.
