Firefox upgrade and website functionality

Pin It

Some websites, which may include some AU websites, will not function correctly in Firefox after it automatically upgrades to version 52, scheduled for release on March 7, 2017. Firefox 52 will remove support for several plug-ins, including Java, Silverlight and Acrobat Reader. These plug-ins give a web browser additional functionality required for some websites.Firefox-logo.svg


What do I need to do?

If you do not use Firefox, or do not encounter any new issues after the update, no action is required.

If you encounter any issues accessing websites with Firefox after the update you can try one or more of the following:

  1. Install Firefox ESR. (More information below.)
  2. Try a different web browser. (Internet Explorer, Edge, Google Chrome, Safari, etc.

When will this happen?

Your Firefox application should automatically update to version 52 after it is released on March 7, 2017. If you are not using the Firefox ESR version some of your plug-ins may stop working after the update.

Why is this happening?

The Firefox website has information on the changes and its effects. web page for more information.


Firefox ESR

What is Firefox ESR?

Firefox ESR is a version primarily intended for organizations that defers the implementation of functionality changes, but still provides regular security updates. Version 52 of Firefox ESR will continue to support these plug-ins until Early 2018.

 

How do I know if I am running Firefox ESR?

This page should provide instructions for finding your Firefox version on your current operating system.

Once you have opened the “About Firefox” window using the directions above, you will see the following if you are running ESR:

– FirefoxESR in large bold letters at the top of the window.

– The line “You are currently on the ESR update channel.”

 

How do I install Firefox ESR?

You can replace your current Firefox install with Firefox ESR in Windows 7 by following these steps. Installation on other operating systems will be slightly different.

  1. Download the latest installer 

NOTE: Most AU Windows users will want to download the “Windows” version, not the “Windows 64-bit” version.

  1. Run the installer.
  2. Click the Next/Upgrade buttons when prompted, you should not need to change any installation options.
  3. Click Finish. (You will be prompted to close Firefox if it is already running.)
  4. Firefox ESR should start, if it doesn’t then start Firefox as you normally would.

Firefox ESR will replace your existing Firefox installation, so you don’t have to worry about running the incorrect version.
