I’ve been dealing with this problem since Firefox iOS came out, but I’m finally getting around to reporting it. On certain websites (mostly financial), I cannot share a PDF displayed in a browser tab to another app. The result is a blank PDF file. For instance, if I display a bank statement PDF in the browser and tap share to Evernote, the resulting Evernote note has an empty PDF of 787 bytes in it, not the actual PDF I was viewing and shared from the browser. I do not have this problem on Safari iOS so I’ve been using that browser for financial websites this entire time but I’d like to get Firefox iOS working properly seeing as iOS 14 will supposedly let us set our default browser of choice. One work-around is to Share > Print > zoom in (pinch out) to make the PDF a PDF again and then share that second PDF to whatever app. The problem with this is that Firefox iOS insists on ugly page header with the garbled URL overlapping itself across the top. There is no way to turn this off. Also and more importantly, it doesn’t always work. The shared PDF will sometimes show an error from the website, noting the lack of credentials to view that page. My guess is that Firefox is not re-using or cannot re-use the existing authentication token. I am running Firefox iOS 28.1 (19225) and iOS 13.7.1.
