Hi

If the file is not showing in the downloads location, how are you sure that the file has Indeed fully downloaded?

I says download finished and also says 100%

I also have this issue on Firefox for iPhone. It’s a frequent headache when trying to download and view PDFs in browser. Such as with all the restaurants that insist on having you scan a QR code to view their menu. These are often PDF. I have Firefox set at my default browser, but I have to copy and paste these urls into Safari to get the pdf to download. I shouldn’t have to do this.

Attached photos show Firefox for iOS doing nothing with the example url that leads to a PDF. Safari properly prompts the user to download the linked PDF as expected.
