Close Firefox if it's running. To lock Firefox with a password, you must first make sure it isn't running. If you're unsure of the program's status, press the "Ctrl," "Alt" and "Delete" keys simultaneously to view all programs running.
2Navigate to the "Start" menu and right-click on the "Firefox" icon. Select "Properties" from the pop-up menu. The Mozilla Firefox Properties dialog appears.
3Click the "Security" tab.
4Highlight the user or usergroup you wish to deny access to the program and click the "Edit" button. If the name of the user doesn't appear, click "Add," type the username and click "Check Names."
You should now be able to add or deny access to the program for the selected user by clicking options in the Permissions box. Edit the options for each user or user group you wish to deny access. Click "Apply" after editing for each user. When finished, click "OK." Next, click "OK" to approve the changes. You have locked the program down and users must now access your unblocked user account by password to access the program. After logging into your user account, you won't have to supply the password to access the program.
5To verify that Firefox is locked, attempt opening the program in a blocked account. Do this by logging out of your user account and logging in as the user you have locked out of Firefox. If you can't access the program, you have successfully locked Firefox with a password.
