Mozilla has released a new version of its browser, Firefox 58, based on a series of advanced Quantum project elements first featured in the previous versions, especially in Firefox 57 in November.
Firefox 57 included a redesigned interface together with a few interface novelties, a giant speed boost (Firefox 57 is twice as quick as Firefox 52), and an engine using 30 percent less memory than Google Chrome. In terms of websites blocking, the introduction of the ability to block ad trackers was of undoubted interest for inveterate web surfers.
Firefox 58 features a series of new goodies of its Gecko engine intended to streamline and speed up its performance. Among such novelties are background tab throttling (reduces CPU usage), the Off-Main-Thread Painting (OMTP) (rendering process is significantly improved) and WebAssembly Streaming Compiler (streaming compilation support).
There are also a few goodies related to the CSS fonts, that reduce their loading times. A new feature called Promise decreases the redundant code. In the Firefox Screenshots, a few novelties have been introduced as well with regard to functionality and privacy.
In the Firefox for Android, an important improvement is a support for Progressive Web Apps (PWAs), which enables the users to add websites to their home screens (making them kind of native applications).
Less significant novelties in the Firefox 58 include a slightly altered procedure to disable cookies on Mac and Windows and other minor changes.
The current Firefox users are welcome to upgrade to Firefox 58 in the automatic mode just by restarting the browser. For the rest of users, Firefox 58 for macOS can be downloaded for free from Mozilla website.
