When your tasks are disrupted by slow or unresponsive pages, it is frustrating and distracting. As such, performance is a key component of <a href=\"https:\/\/www.mozilla.org\/en-US\/about\/webvision\/full\/#performance\">Mozilla\u2019s vision<\/a> for the web.<\/p>\n\n\n\n<p>To deliver against our vision and enable a better online experience for everyone, we\u2019ve been working hard on making Firefox even faster. We\u2019re extremely happy to report that this has resulted in a significant improvement in speed over the past year.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Improvements on benchmarks<\/strong><\/h2>\n\n\n\n<p>One way to judge browser performance is by using industry benchmarks. We have seen measurable improvements here, specifically around the popular benchmark <a href=\"https:\/\/browserbench.org\/Speedometer2.1\/\">Speedometer 2.1<\/a>.&nbsp; This benchmark measures browser responsiveness by simulating user interactions (such as manipulating a list of to-do items).<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/lh7-us.googleusercontent.com\/JycfLdWVg3aahOa4S-3l3AH7d2uJnmwIHJODCVjjhIjGoHDGdw5zIZ9ZhLnBW8e6geZKoZCF4Gj9CbwTU-WZ1-a6aMucqREb8rgRVM4YCtq-yn-VEf5Q59JrsQS0JpnrHI7jvjdwg9Yl5rpt6y9ei-Y\" alt=\"\"\/><\/figure>\n\n\n\n<p>Since January 2023, Firefox\u2019s Speedometer score has improved by 50%, a significant performance improvement for our users.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Performance on the web<\/strong><\/h2>\n\n\n\n<p>Yes, benchmarks matter, but it\u2019s worth pointing out they only simulate what a user could experience. It was important for us to verify that the performance improvements were actually being felt by users.<\/p>\n\n\n\n<p>We&#8217;ve observed improvements on performance metrics that matter. In particular, pages are appearing 15% faster on average:<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/lh7-us.googleusercontent.com\/CCucpMvQ1P91Vumz-WgDN8EjbYWX9wM8agpIxsZrNFCc4P1rwU-OI1FFFYW6_q46WKQ8HGokmSn4gMF2_xImZX1suuBgz0Tpzs_lQwQtJ_oYPppavTB7DdSXdrpeXRhTHydR8U2U_bkE5jbpDZ-nUHU\" alt=\"\"\/><\/figure>\n\n\n\n<p>It is extremely gratifying to see that the improvements in benchmark scores are actually being felt by Firefox users everywhere.
