In previous versions of Firefox (up to version 133), it was possible to automatically trigger printing of a PDF file by loading it into an iframe from a sandboxed iframe and call print. However, starting with version 134, this no longer works.

Is there any other way to automatically trigger the print dialog for a PDF file in Firefox, similar to how it can be done in Chrome/Edge (e.g., by opening the PDF in a new window and directly triggering the print dialog without additional button clicks)?

Could you test today's release of Firefox 134.0.2? It fixed some cross-frame logic that might be relevant to your problem, depending on how you trigger printing.

I tried your solution, but the issue remains.

Previously, I used a sandboxed iframe (iframe1) to load a regular iframe (iframe2) and display a PDF. This allowed me to automatically trigger printing without user interaction. However, since the changes between the 2024-11-13-09-48-33-mozilla-central and 2024-11-13-21-52-56-mozilla-central builds (related to Bug 1724924), PDFs no longer load in sandboxed iframes. Because sandbox restrictions are propagated, iframe2 cannot open the PDF file and trigger printing.

I need a way to automatically print PDFs (opening the print dialog without user interaction), similar to Chrome and Edge, where it's possible to open a PDF in a new window and immediately trigger printing.

Is there any way to automatically print PDFs in Firefox from a sandboxed iframe?

If your user case is working in Ch* and Edge, try to create a new bug on https://bugzilla.mozilla.org
