Installing Firefox-ESR 32-bit


In newer versions of Firefox, NPAPI plugins such as the FBGST plugin are no longer usable. In ESM, this plugin is used to be able to view video streams in full bandwidth mode. Using full bandwidth mode is generally desirable because low bandwidth mode, the only alternative to full bandwidth mode as of the time this guide was written, places the burden of video decoding on the server instead of the workstation and will dramatically limit the maximum frame rate for video that the workstation can view.

Both ESM and Orchid will remain usable and compatible with the latest version of Firefox, but for the reasons above it is often advisable to install an older version of Firefox that is compatible with the FBGST plugin in order to gain access to full bandwidth mode in ESM. This guide outlines the steps to install this Extended Support Release (ESR) version of Firefox and prevent it from updating so that it will continue to support FBGST.



  1. Download the installer here and run it

  2. Click "Next" until you reach the "Setup Type" page and select "Custom"


  3. Continue through the installer until you come to the "Set Up Optional Components" page and un-check the box labeled "Install Maintenance Service


  4. Complete the installation and open Firefox to prepare to disable updates. Be sure to decline any update prompts that you see - you can usually expect to see a Windows warning that Firefox is attempting to install updates when you start Firefox.


Disable Updates

  1. Click on the hamburger menu in the top-right corner of Firefox, then click on "Options," and then click on "Advanced" in the menu on the left-hand side



  2. Click the "Update" tab near the top and select the "Never check for updates" radio button


  3. Type "about:config" into the address bar and press enter. Then, click "I accept the risk!"


  4. Type "app.update.silent" into the search bar, right click it in the list of search results, and click "Toggle" so that it shows "true" in the "value" column. This will prevent Firefox from prompting the user to check for updates.


  5. Type "app.update.url" in the search bar, right click it in the list of search results, and click "Modify." Then, enter any fake URL and click "OK." This will prevent Firefox from communicating with the update server.


  6. Close Firefox. Then, uninstall it from Windows using the "Add or Remove Programs" tool, or similar tool for your version of Windows. After this is completed, repeat the steps in the "Installation" portion of this guide. The update settings will be retained, but any queued updates will be removed.
