Hi there, I'd like to make a feature request. One of the things that I love about Google Chrome is the ability to run single window apps. This is the only feature keeping me from moving to Firefox at this point. I'd like to request that this be added as a feature in Firefox. The command could be something like:

firefox --app=

This would spawn a single app window that does not have tabs to navigate to other apps.

I am waiting for this eagerly on Firefox for Linux. Desktop Shortcut from firefox is not as good as chrome.

Support for Site Specific Browser (SSB) and Progressive Web Apps (PWA) has been dropped in Firefox 86 (bug 1682593), so it is no longer possible to use this feature in current Firefox releases.

If browser.ssb.enabled = true is set on the about:config page in a Firefox version that supports SSB then you have "Open This Site in App Mode" in the drop-down menu that opens if you click the 3-dot "Page actions" button on the location bar.
