Starting with version 73 of Firefox, the browser includes a new feature, the “Site Specific Browser”, which allows any website to run as a desktop application in its own window. It is similar to kiosk mode, but does not force the selected web page to run in full-screen mode.
Firefox is a popular web browser with its own rendering engine, which is very rare in the world of chrome-based browsers. Since 2017, Firefox has the Quantum engine, with a refined user interface codenamed “Photon”. The browser no longer offers support for XUL-based add-ons, so all classic add-ons are outdated and incompatible.
Thanks to the changes made to the engine and user interface, the browser is surprisingly fast. The Firefox user interface has become more responsive, and launching is also much faster. The engine makes web pages much faster than ever before in the Gecko era.

How to Use Firefox Site Specific Browser (SSB)
- Visit any web site that you want to use as an application The Discord Chat application is a good example, because it already has a desktop application that uses the Electron framework to run web technologies as a program, i.e. an SSB/PWA version should look like the existing desktop version.
- Click on the three dots in the address bar to the right of the URL
- Select “Install this website as an application” or “Launch a site-specific browser (This may vary depending on the version you are using).
4 This will install a shortcut to the application directly to your desktop so that you can access it like a normal program. If the application already has a desktop version, you can even use both at the same time if you wish. - To manage your installed websites in the future, navigate to the Hamburgers menu and look for the item “Site Browsers” or “Installed Websites” (depending on your version of Firefox).
6 If you click on a website here, it will be launched in a new window. In the current stable version (Firefox 74), this is all you can do, but both the Developer and Nightly versions contain an “X” on the right side, which you can use to remove the installed website.
