Description

- Edit the selected profile.
- Select Enable Web Browser Plugin for HTTPS Web Filtering on FortiClient.

- Chrome: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome.
- Edge: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge.
- Firefox: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox.
Note:
In the latest EMS versions, there is a new option called 'Enforce WF plugin permission in private browsing' in the profile configuration:

This option forces users to enable 'Allow in Private/Incognito' for the WF plugin in Chrome/Edge/Firefox browsers. It is recommended to enable this option to guarantee the correct inspection and categorization of sites.
Users must manually enable the 'Allow in Private/Incognito' option on the browser's extension settings. Due to the different browser security policies, FortiClient cannot automatically enable this option in private mode.
