Firefox for Android supports rendering PDFs in iframes

[stof]

I tested this using the page at https://adrianroselli.com/2025/10/talkin-tables-at-a11yto-conf.html which embeds a PDF in an iframe (after clicking the Display PDF link, as the initial state of the iframe is not the PDF itself).
Firefox for Android properly renders the PDF (using PDF.js as done in Firefox Desktop).

The assumption that no mobile browsers support the feature does not hold anymore.

Thanks for the update, that's encouraging news. I will revisit the various mobile browsers and their support.

I legitimately hope mobile browser support for PDFs has improved, but if the only browser that supports PDFs is FF (whether for Android or iOS), it wouldn't be enough to sway the default behavior in PDFObject. As it stands, the defaults can be overridden in PDFObject, enabling site owners to (try to) load PDFs in mobile browsers or force PDF.js on mobile devices.
