Firefox 70.0.1 releases: dark mode, new logo and more

1 min read

Mozilla Firefox version 70.0.1 is now available for download from the official website, supporting the most popular operating systems including GNU/Linux, macOS, and Windows. From the version number, you will think that Firefox 70 is a major update to the open-source and cross-platform web browser built by Mozilla. In fact, it is not a major version that provides functional improvements. This version brings a new logo, the new welcome screen, and the built-in dark mode.

The first thing you will notice after installing Firefox 70 is the new Firefox icon that Mozilla released a few months ago. In addition, you’ll notice that all of Firefox’s built-in pages now follow the system dark mode preferences, and the new welcome screen will help you set up Firefox faster. In addition, in this release, the Firefox account toolbar menu has been reorganized to give users faster access to account features and services.

Mozilla enabled a baseline interpreter for JavaScript bytecode execution to improve the overall performance of the web browser. For macOS users, Firefox 70 brings a more efficient compositor, which vastly reduces power consumption. Windows users get WebRender enabled by default for low-resolution devices with integrated Intel graphics.
