14 DAY TRIAL // Earlier this month, we were happy to show you a first look at the number one feature of the Mozilla Firefox 38.0 web browser, the new tab-based preferences page that several other modern web browsers already had built-in for some time now.
As expected, Mozilla released the Firefox 38.0 web browser to users worldwide on May 12, 2015, and it included the new tab-based preferences feature that we talked about when the software was still in Beta stage.
Among other features introduced in Mozilla Firefox 38.0, we can mention Ruby annotation support, WebSocket support in Web Workers, BroadcastChannel API implementation, a 'copy' command for developers, DRM playback support, as well as better web page load times.
Additionally, the Mozilla's powerful web browser also came with deprecation of the autocomplete=off function for username and password fields, native HTML5 playback on YouTube for Mac OS X and GNU/Linux operating systems, and support for encrypted HTML5 video and audio playback.
Mozilla Firefox 38.0 is now available for all supported Ubuntu OSes
The good news for all Ubuntu Linux users is that Canonical has just pushed the latest Mozilla Firefox 38.0 web browser to the main software channels of its supported Ubuntu OSes, including Ubuntu 15.04 (Vivid Vervet), Ubuntu 14.10 (Utopic Unicorn), Ubuntu 14.04 LTS (Trusty Tahr), and Ubuntu 12.04 LTS (Precise Pangolin).
The update should be live for all Ubuntu users today, May 13. To update, you should fire up the Software Updater utility from the Unity Dash, wait for the app to load available updates, and then apply them. Wait for the updates to be applied, while making sure that the Mozilla Firefox web browser is closed. That's it, you've upgraded to Mozilla Firefox 38.0.
In related news, the latest Mozilla Firefox 38.0 web browser is also available for all users of the rolling-release Arch Linux operating system since yesterday, May 12. It might also be available on the software repos of other popular Linux kernel-based OSes, so you should make sure that your system is always up to date.
