Hi @Jukka

Thank you for reaching out the WithSecure Community,

To prevent removing the WithSecure Browser Protection extension in Firefox using GPO, you can follow these steps:

• Download the Firefox policy templates from this link here or here and unzip the file.
• Copy the firefox.adm file to the C:\Windows\PolicyDefinitions folder.
• Open the Group Policy Editor by typing gpedit.msc in the Run dialog box.
• Navigate to Computer Configuration > Administrative Templates > Mozilla > Firefox > Extensions.
• Double-click on the Prevent extensions from being disabled or removed policy and set it to Enabled.
• Click on the Show button and enter the extension ID of the WithSecure Browser Protection extension, which is ols@withsecure.com.
• Click on OK and close the Group Policy Editor.
• Restart Firefox to apply the changes.

NOTE: Please ensure that you use in Client Security/Server Security 16.00 and https://download.sp.f-secure.com/online-safety/fs_firefox_https.xpi in Client Security/Server Security 15.x or Elements EPP for Computers/Servers.

Also, you should use the new extension ID for Mozilla Firefox, ols_main@withsecure.com in Client Security/Server Security 16.00.https://download.withsecure.com/online-safety/ws_firefox_https.xpi

I hope this helps you secure your browser and your online privacy. If you have any other questions, please let me know. 😊
