"We now clearly outperform Chrome in the SunSpider JavaScript test!" - reads the Firefox Nightly developer blog. The claim is supported by a screenshot of a JavaScript test from a decade ago, in which Firefox did indeed easily pull ahead and beat Chrome in performance.

The test was done on the platform. Mozilla's development team didn't mention that on the same platform the results of a newer and more demanding test JetStream 2.0 are given, in which Google Chrome browser turns out to be much faster than Firefox.

The developers of the independent browser also reported that over the past month they have worked to improve the speed of downloading over HTTP/2 protocol and offered a number of other innovations for the preliminary version of the product.

Earlier it became known that the desktop version of the browser lost support for Windows 7, 8 and 8.1, as well as older versions of macOS; meanwhile, Firefox for Android will soon have full support for third-party extensions.
