With this add-on you can also add new websites to each profile. Press the Add new website button on the left of the Switchy Manager tab to open the page below. Enter a URL in the Add Your Website text box, and choose a profile to add it to. Below that you can select either the Open on startup of these profiles or Open on exclusive of these profiles (a notification bar will be shown when this URL will be open on other profiles) options. Then press the Create button at the bottom of the page.
Overall, Switchy adds handy user profile shortcuts to Firefox and offers better profile management. If you browse with multiple user accounts, Switchy will be a handy addition to Firefox.
