 <color red>**08/22/2024 – Note:**</color> The above “fix” only seems to hold for the current browser session; if you close the browser, then the **browser.tabs.hoverPreview.enabled** option gets reset to true when the browser starts again.  Still working on a fix for this, but it might involve dumping Firefox for a different browser.  More to come.
+==== Disable "What's New" page after a Firefox software update ====
+  * In about:config, search for **browser.startup.homepage_override.mstone** and set it to ''ignore''.

 ===== Browser Management =====
+==== Disabling Application Updates ====
+Create a **policies.json** file with the following contents:
+<file json policies.json>
+  {
+    "policies": {
+      "DisableAppUpdate": true
+    }
+  }
+</file>
+Based on the operating system involved, save this file at the following location:
+  * **Windows** - ''C:\Program Files\Mozilla Firefox\distribution\policies.json'' (admin rights required)
+  * **MacOS** - ''/Applications/Firefox.app/Contents/Resources/distribution/policies.json''
+  * **Linux** - ''/usr/lib/firefox/distribution/policies.json'' (or ''/etc/firefox/policies/'')
+==== Moving To Another Machine (Windows) ====
+  - Within the browser, go to ''about:support''
+  - On the resulting screen, locate the **Profile Folder** and click the **Open Folder** button.
+  - The profile folder will open within File Explorer.  Make note of the directory name and then click back one level to the **Profiles** directory.
+  - Find the folder noted in the previous step and copy it in its entirety to a USB stick or network drive share.
+  - On the new machine, perform steps 1-3 above.
+  - Make sure Firefox is closed, then rename the existing profile directory to something else.
+  - Copy the saved Profile directory to this location, making sure to rename it to match the profile name the new machine is expecting.
+  - Navigate to the profile directory in File Explorer and either delete or rename the following files: ''addons.json'', ''compatibility.ini'', and ''extensions.json''.
+  - Start the browser; it should reflect how it was set up in the previous location.
