PDF viewer extremly slow

[Entwicklung]

Since a few versions ago, the pdf viewer built into Firefox has been extremely slow for some documents.

Unfortunately, I have not yet been able to determine what the slowly displayed PDF files have in common.

It is not due to the size. Even PDF documents with only one page sometimes take up to 4 seconds until the PDF page is displayed.

It's not because of my computer. Intel Xeon, 32 GB RAM

The PDF is embedded with the HTML tag object.

@Entwicklungcan you share one or more PDF documents where you're experiencing this slowness?

Hello Marco,

thank you for asking.

The performance problem only arose under Microsoft Windows 10. The problem no longer occurs with version 11, which is now in use.

Regards,

Michael
