I am using the FireFox PDF Editor to annotate a PDF, however, no method of me saving the document (whether that is save as, or save as PDF) will allow me to save any annotations on the document. If I try doing save as PDF, the preview shows up as blank sheets of paper, when I click "save as" it only saves one page of the 31 as BLANK. If I try doing normal save as, the saved file is un-annotated.

Please help... thanks

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

Lately, whenever I try to open a PDF from a website open in Firefox, the tab crashes and the PDF does not open. An error stating that the Windows file-dialog has crashed is displayed at the top of the tab. I tried to attach a screenshot of the error but that action only generates another error.

This condition does not occur when I try to open the same PDF from the same website open in either Chrome or Edge, the PDF opens properly which leads me to believe the problem is in Firefox and not my Adobe installation.

Thank you

Firefox 138.0.1, MacOS Monterey 12.3

PDF files: settings is set to "Always ask" (see attached) However, when I click on a PDF link, and get the dialog "Open With" is grayed out, and the only option available is "Save File" (see attached screenshot). (A few weeks or months ago it all worked correctly.)

Is there a way to get "Open" working again?

Hello: recently I decided to ditch expensive PDF Converter apps for my desktop pc as overspecified for my purposes. To date, I haven't found any guidance to use the Firefox Easy PDF Converter - usually required to convert Lotus Word Pro or MS Word text documents to pdf format. As a second request, can it be used to reverse convert e.g. pdf to docx etc. I have already added it to my Firefox app, but can't go any further. Thank you for helping. Geoff Pickerell (UK)

For about a week now, I have been unable to read any pdf document I download. The body of the document is completely black (that is black, not blank). When I go to save the document, it is saved as a black (unreadable) document. I have had to switch to using another browser in order to be able to download/save a readable pdf document. How can I fix this issue?

Mozilla/Firefox is my browser. Lately, every time I am on a website where I need to open a pdf document, like a bank statement I want to download, a pop-up appears that advises me to sign on the dotted line or anywhere and shows a little pen writing something. Underneath is this sentence: "Draw, type or upload your signature, then place it exactly where you want. Save your go-to signature for next time."

Where did that come from? It blocks my view of the document and if i try to capture it in a "screenshot" nothing appears. Is this a Mozilla/Firefox thing or a (Acrobat) pdf thing? And what can I do to stop it?

I create and save files in OneDrive. When I open a file, it always opens in the Microsoft Edge Browser which is a problem for the old guy, me. I prefer that they open only in the documents folder as their specific kind of document; Word, PDF, and Excel spreadsheet files so that I can then move my files into various folders and sub-files. Hopefully, someone can figure out what I have said and help me. • I'm uncertain if the topic I chose accurately describes my question.

When I open a PDF in Firefox, a half-page notice opens, telling me I can highlight the PDF. This prevents me from doing absolutely everything. Cannot read the file, cannot print the file with the box in the way. How can I get rid of this box? Thanks for your time.

See the attached image. This showed up when viewing PDFs. The highlighter demo can not be removed or turned off. I uninstalled Firefox, reinstalled, still there. Uninstalled Acrobat, the demo is still there.

There is an issue with PDFs downloaded using the Firefox PDF viewer. The PDF contains a valid digital signature. When I set the parameter pdfjs.disabled = true, everything works as expected, the PDF is downloaded correctly, and when I open it with Adobe Reader, the signature is valid. However, when I set this parameter to false (default value) and download the PDF using the built-in Firefox PDF viewer, the signature becomes invalid. I compared both PDF files using a text editor and a diff tool, and the only difference I found was a specific change in the content. 1)pdf- signature is valid Ψα Exif II* μ Ducky d α http://ns.adobe.com/xap/1.0/ <x:xmpmeta xmlns:x="adobe:ns:meta/" x:xmptk="Adobe XMP Core 5.6-c138 79.159824, 2016/09/14-01:09:01 "> <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"> <rdf:Description rdf:about="" xmlns:xmpMM="http://ns.adobe.com/xap/1.0/mm/" xmlns:stRef="http://ns.adobe.com/xap/1.0/sType/ResourceRef#" xmlns:xmp="http://ns.adobe.com/xap/1.0/" xmpMM:DocumentID="xmp.did:FF61BC20787811E896E6E83BD502C18A" xmpMM:InstanceID="xmp.iid:FF61BC1F787811E896E6E83BD502C18A" xmp:CreatorTool="paint.net 4.0.16"> <xmpMM:DerivedFrom stRef:instanceID="452A56456B1E68A148301EBAD51349D5" stRef:documentID="452A56456B1E68A148301EBAD51349D5"/> </rdf:Description> </rdf:RDF> </x:xmpmeta> ξ Adobe dΐ Ϋ „ ΐ F F Δ • 2)invalid pdf Ψα Exif μ Ducky d α http://ns.adobe.com/xap/1.0/ <x:xmpmeta xmlns:x="adobe:ns:meta/" x:xmptk="Adobe XMP Core 5.6-c138 79.159824, 2016/09/14-01:09:01 "> <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"> <rdf:Description rdf:about="" xmlns:xmpMM="http://ns.adobe.com/xap/1.0/mm/" xmlns:stRef="http://ns.adobe.com/xap/1.0/sType/ResourceRef#" xmlns:xmp="http://ns.adobe.com/xap/1.0/" xmpMM:DocumentID="xmp.did:FF61BC20787811E896E6E83BD502C18A" xmpMM:InstanceID="xmp.iid:FF61BC1F787811E896E6E83BD502C18A" xmp:CreatorTool="paint.net 4.0.16"> <xmpMM:DerivedFrom stRef:instanceID="452A56456B1E68A148301EBAD51349D5" stRef:documentID="452A56456B1E68A148301EBAD51349D5"/> </rdf:Description> </rdf:RDF> </x:xmpmeta> ξ Adobe dΐ Ϋ „ ΐ F F Δ • I cannot understand why the Firefox PDF viewer modifies the PDF content.
