Mozilla Firefox 30 is now available for download - Here's what is new

Mozilla Firefox 30Mozilla has just released Firefox version 30.0 for Windows, Mac, Linux and Android. Firefox 30 is a minor update in terms of functionality that has been added or changed in the browser. This is in stark contrast to Firefox 29 which introduced the Australis interface to the browser.

You can download the update to your device by heading over to Help > About on your Firefox browser or by pointing your browser to You can also download the latest version and install the update manually using the links which follow

Firefox 30 brings the following changes

  • Most plugins are not activated by default - Unless the plugin has been whitelisted by Mozilla, it will be deactivated by default. When a webpage requires that plugin, the user will be prompted to enable it. It includes Adobe Flash and several other popular plugins such as Unity, Skype and several McAfee plugins. What you won't find on the list are Java, Google Update, Silverlight or Microsoft Office.
  • Support for GStreamer 1.0 - Probably the biggest feature addition of Firefox 30 is support for GStreamer 1.0. Firefox up until now supported GStreamer 0.1 only which, while still supported is being replaced with the newer version which means that many Linux distributions will move over to GStreamer 1.0 eventually (or may have done so already). GStreamer adds H.264 video as well as mp3 and aac audio support on Linux systems with GStreamer so that contents can be played directly in the web browser. (source)
  • New Sidebar Button - You can display bookmarks and the browsing history in a sidebar in Firefox. This can either be done with a tap on Alt and the selection of View > Sidebar or by using the shortcuts Ctrl-B to display bookmarks in the sidebar or Ctrl-H to display the history instead.

    Additional contents, such as social providers or tabs (via third-party add-ons), can be displayed in sidebars in the browser as well.

    While only a handful providers support Firefox's Social API, Facebook even removed its implementation again, it is something that Mozilla puts a lot of focus on.

    The new sidebar button is available in the customization menu. You can drag and drop it to another location of the browser for easy access. When clicked on, it displays the available sidebars so that you can open and close them easily using the button.
