Lenovo notebook firefox is a free and powerful browser, and Express can support it. When installing Express, if the Firefox browser is installed on the system, Express will automatically add support plug-ins to Firefox. After reopening Firefox, you will find that the plug-in has been installed.
Situation 1: If firefox is installed on the system but has not been added support, please open the express menu bar "Tools" button, select "Browser Support" and left-click "Add Firefox Support".
Scenario 2: If the error message "Add Firefox support error, Firefox component path cannot be found" appears during the above operation, please try to reinstall your firefox and then perform this operation again.
