You will need to install Securly’s SSL certificate in Firefox to allow users to seamlessly browse HTTPS sites, and also help Securly decrypt them appropriately.
Deploying the Securly SSL Decryption Certificate to Firefox can be difficult because Firefox does not respect the Operating System settings and there is no native way to centrally manage Firefox. This article describes how Firefox can be configured to trust the Windows certificate store which makes certificate management much easier.
Note that the following guidance is provided 'as is' and cannot be directly supported by Securly beyond what is outlined in this article.
Distributing Firefox Preferences Files via Group Policy
Group policy can be used to distribute the above files.
Note that this process requires Firefox to be installed to the default location on the client's computer.

- Create/Edit a group policy in the "Group Policy Management".
- Edit the settings in 'Computer Configuration > Preferences > Windows Settings > Files'.
- Right-click and select 'New File'.
- Point the 'Source File' to securly.cfg on the Network Share.
- Point out the 'Destination' file to be C:\Program Files\Mozilla Firefox\securly.cfg and 'Apply'.
- Repeat the above step to copy the same file to C:\Program Files (x86)\Mozilla Firefox\securly.cfg
- Repeat these steps to copy 'local-settings.js' to C:\Program Files\Mozilla Firefox\defaults\pref\local-settings.js
- Repeat these steps to copy 'local-settings.js' to C:\Program Files (x86)\Mozilla Firefox\defaults\pref\local-settings.js
