Google Docs widget works only partially on Firefox

[killua-eu]

Description

Tried to add the publicly available google doc https://docs.google.com/document/d/1lWOh2U85ZQ9mJq0QMwj6WDVvbDDj-AaImfD-FRnD0UE/edit , only google docs ui loads, no content to be seen / to be edited. This happens solely on firefox (tried up to the latest FF beta available: 56.0~b6+build1-0ubuntu0.17.04.1, works well on chromium). The console output tells:

Persisting sync data up to  s15897_616500_270_20178_4378_73_546_952

So I'd assume its either the CORS or the uncaught exception at which the console output stopped or these two are related.

Steps to reproduce

Use latest firefox with Google docs.

Still a problem on Firefox 57

[kittykat]

Can anyone still reproduce this with the latest version of Firefox?

I'm going to close this issue for now as it is against an old version of Firefox. Please reply with @kittykat if it is still valid for you.
