1. On your server, create a shared network folder.

2. Ensure that permissions on this folder allow access from users/computers that you want to deploy to.

3. Download the required files from the following link - Firefox Files.

4. Unzip the folder and place the three files into your shared network folder.

"jid1-zEiCurjQJsFu6g@jetpack.xpi"

"mozilla.cfg"

5. Open Group Policy Management.

6. Create a new GPO for the policy (or add to an existing policy).
