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.

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 🙏🏻).

This is great! It works much better than I expected.
I couldn't get the extension to work in Firefox installed via Snap on Ubuntu, but that doesn’t bother me at all.
Thank you!

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!

It seems to work well but the update process is constant, and the extension itself does not seem to recognize if and when it needs updating.

Further it is unclear (from the user perspective) *WHAT EXACTLY* needs updating. There's the standalone install (what is that called?) -vs- the stuff that gets installed in the Firefox folder... and is there more? I've updated the standalone install but it still complains it needs to be updated - well OK then do it, I am not sure what else I am supposed to do?

As far as I can tell I am up to date - 2.14.1 [application installed in C:\Program Files (x86)], and extension is still at 2.13.3 on this very page, but the extension is complaining I still need to update.
