Firefox Web Apps loading as "blank"

[scottyd]

This seems replicatable on my machine. In the first instance of creating a webapp (Whatsapp and Youtube Music have been created) the pages show fine. Subsequent opens though are hit and miss, but once they miss, I see a blank page and from then on it fails to load every time.

Happy to help out any other way.

Confirming this with whatsapp and threema.
Reboot your machine, first time it opens. If you close all the windows and reopen.. no joy. Tried to "killall firefox" and tried, still no joy.
EDIT: I think this isn't related to webapp-manager. i just installed and tried "ICE" from ppermintOS: https://launchpad.net/~peppermintos/+archive/ubuntu/ice-dev/+files/ice_6.0.7_all.deb

the behaviour is the same. Any ideas?

Same issue. Any ideas?

After a firefox update, the app loaded again - only once - and then has gone blank.
I have noticed that clearing the cookies allows the page to load once - but that is an unacceptable solution as it causes the user to sign-in each time.
I enabled the navigation bar, manually added a tab and entered the website address... and it wouldn't load - apparently stuck.

Works fine when configured with Chromium... so I might use Chromium for this purpose.

Same issue here with Twitter and Spotify webapps. Although the YouTube webapp seems to load fine almost every time. Using Firefox in all of them as well.

Blanks also occur after adding extensions such as Darkreader on Firefox, at least.

I can't reproduce this at all here.. can you see if you can find the source of the issue? Troubleshoot the web console etc..

oh wait.. make sure there's an URL when you edit these webapps. I'm just thinking.. this could be related to the fact that URL is now editable (it wasn't before), but it's not able to edit webapps which were created beforehand that change was made (during the BETA phase). If the URL is empty the page will be blank.

Same issue here with Outlook Web App.

For me enabling clear history when Firefox closes fixed this.

@hduelme's suggestion worked for me now my webapps open consistently, it's not an ideal solution though because it obviously clears any saved credentials.

I wonder if there's a specific item of data that, if kept, causes Firefox to load a blank page?

This didn't work for me.

Same problem here with the same "NS_BINDING_ABORTED " error. Spotify shows a blank screen. Only works after reboot or clearing cache.

I really would like to use this instead of the proprietary binaries...
Discord works though!

Any news on this issue? I'm having to run Spotify's webapp on Brave in order to avoid it, but would rather use Firefox's addon ecosystem.

As far as I know the issue has been fixed when the stable versions were released(at least 1.1.2. IDK the which was the first stable release.). Now on 1.1.5 I don't get any such issues for any usual websites. But this issue was not closed.
