The 64-bit version of Firefox is not currently supported. To make full use of Lansweeper and its asset/user actions, it is recommended that you use the 32-bit version of Firefox or a different browser.
To configure Mozilla Firefox to run asset and user actions, do the following:
Open Firefox, access this link and, if prompted, click Allow and Install. This will install the plugin required to run asset and user actions.
Restart Firefox. To ensure that Firefox is fully stopped before restarting, you can open Windows Task Manager (Ctrl+Shift+Esc), right-click the firefox.exe process(es) under Processes and select End Process.
You can check whether the plugin is properly installed by accessing Firefox's Add-ons menu. You can access it directly by using the Ctrl+Shift+A shortcut. You can disable/re-enable the plugin from here as well.
