Google Chrome allows us to create shortcuts for websites that you can use to run the specified sites in a separate window using the shortcuts they create, which Firefox has not supported so far, but Mozilla is at Firefox The Site-specific Browsing (SSB) feature has been implemented in version 73. Currently, The Nightly version of Firefox 73 allows users to open websites in a site-specific browser with a button in the Page Action menu.
It is important to note that websites launched in this way do not appear to have elements such as toolbars, navigation menus, kiosk mode and full-screen mode, and additional browser windows need to be launched if you need to easily browse other sites.
Officially, site-specific browsers or SSBs mean running a single site in a separate browser instance and not relying on the overall browser session, and SSB’s minimalist interface (without toolbar) allows users to focus on content.
In the past, Mozilla Labs introduced APrism based on the SSB concept, but later removed this feature, according to Mozilla, a simple XULRunner-based browser that can host Web applications without a regular Web browser user interface.” In the past, Prism used to create shortcuts to websites and run them as SSBs.
Although you can’t create a desktop shortcut to launch a website as an SSB, you can now open the site as SSB in Firefox right now, so you should run the latest version of Firefox Nigthly.
