Honestly thing thing is fantastic. FF probably will never bring native PWA back to FF. Zen is also a ways out, but this extension is near flawless. Use it every day. It is well executed, reliable, and makes my life better. Thank you!

Still works well but the latest update degraded functionality a bit. Icons often have to be manually added to the PWA, and the Windows OS can no longer store persistent links to the PWA in the taskbar - "pin to taskbar" results in a link that gets invalidated every time FF starts. IIRC that feature used to work.

I like the app and i can run it on debian, but installing on Ubuntu isn't successful yet.

Working great! I can use multiple profiles to access the same website with alternative accounts, and I can sync all my Firefox apps to access there as well (uBlock and Bitwarden 🙏🏻).

First time user: I successfully installed a PWA but when launch pressed only a blank page appeared.

Marvellous. Very well integrated in kde menus

PWAs on Firefox – that's actually something I've wanted for a long time. I use them for MS Teams and, what can I say (?), at least as good as the variant that works with the other browser engine.
To all decision-makers at Mozilla: please reconsider your decision regarding support for PWAs. At the very least, you should praise Filip Štamcar and officially recommend his plugin.

The last feature that I was missing in Firefox was PWA. Thank you!
