Firefox summarizes progress in 2023: web page loading

Firefox summarizes progress in 2023: web page loading, keyboard response and JS execution speed have been improved.

Mozilla recently issued an official press release taking stock of the progress made by FireFox in 2023. It mainly made three major improvements in speed, namely web page loading speed, keyboard response speed, JavaScript execution time .

It is reported that Mozilla is based on Speedometer 3 and analyzes the data to improve the web experience by collecting user data reports such as page loading, response speed, startup, etc.

We have compiled the specific content as follows:

Optimize web page loading speed

On the web, Mozilla uses the “First Contentful Paint” metric (the time it takes for the browser to fully load a web page) to measure browser performance.

Mozilla claims that these data represent significant improvements in speed of the Firefox browser in 2023. These improvements are achieved by optimizing the performance of the browser and the JavaScript engine. The relevant team will conduct more optimizations next year and will do so in the future.
