To manage your installed websites in the future, navigate to the hamburger menu and find the “Site Browsers” or “Installed websites” item (depends on your Firefox version).If the app already has a desktop version, you can even use them both at the same time if you want. This will install a shortcut to the app directly onto your desktop, allowing you to access it like you would a normal program.Select either “Install this website as app” or “Launch Site Specific Browser.” (This may vary depending on the version you’re using.).Click the three dots in the address bar to the right of the URL.The Discord chat app is a good example because it already has a desktop app that uses the Electron framework to run web technologies as a program, which means an SSB/PWA version should look quite similar to the existing desktop version.

It also strips out a lot of your browser’s toolbars, menus, and other UI functionality (the current Firefox implementation as of version 74 especially takes a lot out), limiting you mostly to what the website is programmed to do. That means some sites can become “first-class citizens,” with taskbar buttons, offline functionality, program-like launching, and other perks that make them more usable than traditional browser-based sites.

What does a site-specific browser do? #Ī site-specific browser essentially creates an “app” out of any website, running in a separate browser instance and behaving like a desktop app. It’s currently hidden as an experimental feature, but you can still enable and use it in any major Firefox browser version (Nightly, Developer, Beta, stable) before it’s eventually rolled out and becomes available by default.
