I don't see an issue there

OK this seems to be a browser issue (Firefox)
Thank you

Try updating your browser etc and then if there is still any issue then check your developer console and screenshot it and we can help you.

Firefox is up to date on both systems (Ubuntu 19.04 and Windows 10),

@Manuela: Can you try with this URL and see if it still happens? https://lilypond.miraheze.org/wiki/Datei:Arbeitsheft.pdf?safemode=1

Nothing has changed with this URL, sry.

I'd guess it must be a Firefox / PDFembed issue then. I'll see if anyone can reproduce and we'll look at maybe Upstream ing this.

Reproduced

It must be an issue with firefox because I have tried it on chrome on macOS and it worked. But then I tried it with Mozilla Firefox and all that came up is a blank page. @Manuela for the time being until this gets fixed I would suggest using Google Chrome (which in my opinion is better anyway :P) . You can download it at https://chrome.google.com. Hopefully the developer will fix the issue soon.

Hi, I am using both browers parallel, my favorite is Firefox.

@Examknow This is upstream

@Manuela Is this issue still occuring?

Thanks for asking. I found a workaround, so I did not check for a long time. It is working now,.
