I apologize in advance this problem seems so strange to me that I can't even properly search for it... Quite often I have to save PDFs from the browser using the download option.

enter image description here

This is all fine but in the next step, when I click save I get prompted the 'save as' window. And this window is locked to the Firefox Window behind it. That means if I try to move it the Browser window behind it moves with it.

Why do I want to move it? Because I would like to see the title and the authors of the document in order to give the file a meaningful title. This is no longer possible for me.

This started happening after I updated to Ubuntu 20.04. I find this behaviour quite irritating and would be very glad for any suggestions on how to resolve this.

Sorry for not providing more information at this point, I'm really a bit at a loss what could be happening here. But happy to follow up.

  • Yes!! Thank you! Just like the poster in the link you provided I did not even have the right vocabulary to search for it - sorry for duplicating it :)
