I don’t know what that button does but I’m fairly sure it’s not about support for web-apps. Firefox has always supported web-apps, because web-apps are just interactive websites.

That’s from August, when support was added back after the feature being dropped in 2020.
Mozilla has released Firefox 143.0. The update lets users pin web apps to the taskbar, but only on Windows.
About a month [ago], I reported that progressive web apps (PWAs) are available via Firefox’s Labs. Now, the feature is available for everyone on Windows.
Progressive Web-apps are a particular kind of web-app. The person you replied to just referred to “webapps”, not this special kind of web-app. Firefox has always supported web-apps.
The nature of progressive web-apps means that you can use them even if the browser doesn’t explicitly support them. All that explicit support does is wrap the web-app in an icon and reduced browser window.
They’re now supported on Firefox on Android, so good news!
Webapps are now supported on Firefox? Holy smokes!
Yup!

It’s the button to pin a PWA to the taskbar by reading the manifest.json

About time!
Thanks for the great news!
