I just updated to 3.0.10.10 and this problem is back. The dock icons for my existing apps no longer work and I get the same error as previously when I try to make new apps.

When I launch the existing apps from the fireworks window, they don't
appear in my dock even if I right click and "move to launchpad".

Looks like its working great now! Thanks!

macos 10.12.6

I tried http://messenger.com, http://mail.google.com, http://gmail.com, http://google.com

It still doesn't work. When I use the "As application in Launchpad" I get an error message "Error, please check web application URL".

If I use the middle option, a web application is created  but then I can't see it in the dock.

I downloaded the most recent version 10 min ago just to be safe.

Continuing the conversation from product hunt about pinning apps to the dock.

How do you try to pin a web app to Dock? We assume the usual way to
pinning to Dock, as it works for other applications. Please tell me what
you got.

I'm new to firework so maybe this isn't the usual way:

Open firework, added gmail with a new profile, right click on the icon in the gallery and choose add to launchpad.

I don't see anything in the dock or the launchpad.

I just downloaded firework on 2017/12/4 and have version 3.0.7.29 running on macos 10.12.6
