Download Firefox 63, See All New Features, Updates And Fixes


The stable build of Mozilla Firefox 63 has been released improving the performance for browsing and online gaming. Firefox 63 Quantum consumes less memory and speed up the page loading in different tabs. Anti tracker technology has further made the web browser light.  The latest version provides several customization features like extensions, themes and toolbar.

Firefox 63 comes with the themes that match Windows 10 OS dark and light modes. Now you can block content easily and much more. Just keep reading.

Mozilla seems to have removed “Never check for updates” option for Firefox users which is a little disappointing owing to the fact that we won’t be able to disable Firefox updates unless we are an enterprise user.

If you are a developer, Firefox 63 brings you a refreshed visual style for Developer tools. Let’s go through each new feature and fix one by one.

Firefox 63 new features

Let’s discuss the new features first.

Content Blocking

Firefox 63 can block all cookies and trackers from third party which cause lag in the speeds. You can select that whether you want to stop third parties from tracking you. A shield icon will appear on the address bar whenever the Firefox detects the tracking and stops it . You can turn the content blocking on and off as you desire. For this go to Options –> Privacy and Security.


Mozilla have started selling subscriptions for ProtonVPN. This will be available on October 24 for small group of Firefox users. The monthly subscription will charge for $10. Selected users from US will be able to see the VPN to check the feasibility of this feature before making it public to everyone.

Picture-in-Picture Video

Support for Picture-in-Picture video has been added but that is limited to certain websites. This feature can  be accessed on Android 8.0 Oreo or later . Visit the supported websites and then press Home button to watch videos on floating window.

The updated Firefox for Android can minimize animation effects by identifying the operating system accessibility setting. English versions from Canada (en-CA) and Ligurian (lij) in the form of new locales are also available.

Performance and visual improvements

If you are a Windows user, you will notice a delightful increase in performance of the new Firefox. This is because Mozilla has move the build infrastructure of Firefox to Clang toolchain. This brings essential performance improvements.

Mozilla has also improved the performance of Firefox 63 on Mac OS. Mac OS users will be able to see improved response from the browser while browsing and also switching tabs on the Firefox window.

In Linux, the WebExtensions will run in their own processes making the browser more stable and responsive.

Fixed and changed features in Firefox 63

There is only one bug that seems to be fixed in this release of Firefox. The issue that prevented the address bar from autofilling bookmarked URLs in certain cases has been resolved.

Open in Sidebar feature for individual websites has been removed. Before Firefox 63, users could open additional web pages in the sidebar. This feature is still present in Vivaldi and Opera and is very useful for power users. I wonder why Mozilla has thought against this useful feature.

Another disappointing feature that has been removed is the “Never check for updates” option. From now on, like Microsoft in Windows 10, Mozilla will force users to upgrade to the latest version of Firefox apart from the fact whether they want to upgrade or not.

Firefox 63 comes with refreshed visual style of developer tools menus. The Dev Tools accessibility inspector is enabled by default.
