These add-ons will be visible in the browser with an additional button that is visible to the right of the address bar. Through this button it will be possible to maintain any userscripts you install.
For WME Tab Manager, you should be able to install the script at Greasy Fork. There will be a big green install button which you will have to press to install the script.
