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!

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!

EDIT:
Developers Solution worked like a charm, great extension!
_______________
Currently not possible for me to update to 2.13.3. I tried updating various ways to uninstall and re install the new package but the page on where you update with visual c and the new installer for the package does not get redirected afterwards nomatter what I do.

agora tem versão português Brazil rsrs

For those who are laymen like me in these matters, the GitHub website is not very intuitive, if you use Windows 11 64, please select and download the file named "firefoxpwa-2.13.2-x86_64.msi" and install it normally on your Windows. The developer fails to provide precise guidance for those who don't know exactly how everything works, as these people don't know which extension they should download, but their work is to be congratulated, this PWA tool is excellent..

it is really useful!

Great stuff. Just wanted to leave this note in case current users come here after theirs breaks: The native program has to be manually updated to support the latest Firefox. Go to github - filips123/PWAsForFirefox/issues/611

Great add on and works perfectly fine for me.
I would appreciate if the PWA can safe login cookies, so that I don't have to type my password every time I start the app.
