Recently, PDF files and sometimes Youtube videos won't display properly in Firefox. Instead, it shows distorted portions of recently closed tabs and/or my desktop background. I can refresh the videos and that fixes them. However, I can't do anything about the PDFs. If I want to view the PDFs, I have to download them. Does anyone know what's going and how I can fix it?

Hello, thank you for having contacted us

You can not change the fichiés PDF, and to read them he will always downloaded on Mozilla.

If not for your own history of youtube videos and background screens I think it's a virus.

Thank you
