PDF Files Display as Blank in Firefox – Request for Investigation and Resolution
Dear Firefox Support Team,
I am encountering an issue where PDF files fail to display properly in Firefox, appearing as blank pages. This problem persists across multiple PDF documents, suggesting a potential browser compatibility or configuration issue.
Request: Please investigate this behavior to identify the root cause (e.g., rendering engine, plugin settings, or recent updates). Adjust Firefox’s default PDF handling settings or implement necessary fixes to ensure proper PDF display.
Additional Details:
- Firefox Version: All
- OS: Windows & Mac
- File link: https://res.mdpi.com/data/pharmaceuticals-18-00847-v4.pdf
- Steps to Reproduce: Open any PDF file → Blank page appears.
This issue impacts productivity and user experience. Kindly prioritize resolving it or provide workarounds. Thank you for your attention.
Best regards, Mia Yu [email removed]@mdpi.com/[email hidden]@qq.com

Home or work? Works for me. see screenshot What OS? If windows, home or pro and what security software are you running besides MS Defender? What version of Firefox?
I can confirm that 6th page is empty in Firefox.
@jonzn4SUSE, your screenshot shows the 1st page, which is OK.
I talked with the team and they've just pushed the update that should fix it.
ETA: version 141.

Thanks. I noticed the status of this bug has been updated to fixed. But the 6th pages is still blank. Could you help take a look? It is important to ensure that all Firefox users see the correct files.
Thanks in advance.
Yes, I can confirm that it looks good in version 141 (Nightly). But I'm sure you and a majority of users have version 139.

Thank you for your quick response and fix regarding the PDF display issue. I’ve tried the Nightly version, and it now renders correctly—I really appreciate the prompt attention to this problem.
I’d like to ask:
Will this fix be included in an upcoming stable release?
If so, do you have an estimated timeline for its rollout?
