Firefox Community Forum

Instructions begin with "Click on the three horizontal lines and select OPTIONS." My updated version of Firefox does not have OPTIONS. Reinstalling Firefox did not solve the problem. In OPTIONS, PDF is supposed to be in the list. Opening a pdf file in Firefox did not cause an edit option to appear.

I just had a Firefox update and it stated: Edit PDFs in Firefox. How do I find this feature? I've looked in settings and all things listed from the "hamburger" menu and can't find it.

Firefox has been used to open PDFs. Suddenly, all the PDFs appear as totally black. If I hover over the tab for that PDF, it shows the little representation as normal white background. This just happened. Don't know how to correct for this.

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)?

Hello,

I have a PDF that opens and displays correctly in Adobe as well as the Edge Browser.

However, when I attempt to open it in Firefox in Windows 11 it doesn't show the letter "i" - - - I swear I'm not making it up. I had a friend try to open it in her Firefox (Windows 10) the letter "i" is also missing.

I wish I could attach the actual PDF so others can test but I will add a screenshot to this message.

Regards,

Paul

I have a question about using Firefox PDF Editor. I copied some text from a PDF document that is on my computer, by highlighting the text and then hitting Ctrl+C. The text copied onto my clipboard OK. Then I opened a blank PDF document in the Firefox PDF Editor and tried to paste that text into the blank document, but I wasn't able to do so because when I right-clicked on the blank document and then clicked on "paste", nothing happened. This apparently is because the word "paste" is faded-out in the drop-down menu (i.e., it does not appear in prominent bold print). Google's Artificial Intelligence seems to indicate that the technique I used would work (see screenshot which I've uploaded). But it didn't work, so can anyone please tell me how can I paste text into that blank document?

I am using Firefox version 136.0.1 and we have multiple PDFs that are password protected (please see attached screenshot from Adobe Acrobat).

When the PDFs are opened in Firefox, it allows the user to add annotation/text/draw which we do not want to happen hence we added restrictions to the PDF. It seems to me that Firefox does not respect the security added to the file. How can I restrict annotations to the PDF or at least require password when the user tries to add text to it?

The following viewers/editors ask for password before you can edit them (expeted): - Chrome - Edge - Adobe Acrobat Pro

Thank you.

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. This is happening only to version 136.0.2. I had no issue before this version. Could you please help me?

I get bills in PDF form from my water and gas provider. When I pay the bills I use Adobe to add a "PAID" sticker and a comment indicating when the bill was paid, and then I save the PDF (from Adobe) with the newly added comment. Previously I was able to open these PDFs in Firefox and the contents of the comment (added via Adobe) was visible; however, recently when I used Adobe to add a comment to a PDF and then opened it in Firefox the contents of the comment were not displayed (NOTE: I opened the PDF in Edge and it displays the contents of the comment, but it doesn't display with the same wrapping as used when the comment was created in Adobe). Interestingly, older PDFs that I added comments to still open correctly in Firefox i.e. they display the contents of the comment. I am assuming there has been some sort of update to Adobe, and was wondering if there needs to be an update to Firefox to continue to allow the contents of comments in the PDF to be displayed.

Is this an extension on the browser ? Do not see how it functions... Many Tks

Recently, I am unable to open PDF's on Firefox. When I go to another browser and access the same site (such as a bank) I am able to view the PDF. I have tried some of the suggestions regarding extensions etc, but nothing seems to work. Is there a solution? Thanks, SVS

Your browser needs immediate attention! I have windows 11. When I visit websites via Firefox and click on a link that takes me to a document, a large pop-up on the lower right side of the screen appears blocking half the page and preventing me from downloading or printing it. The pop-up depicts a cartoon-letter with a highlighter pen traversing its cartoon-text, below which is an enthusiastic missive stating (and I quote): "Now you can highlight your PDFs! With our new highlighter tool, you can read and edit PDFs in one place." Because of this infernal nuisance, I cannot print or download web pages. This has been going on for WEEKS! (That pop-up is USEFUL?! Who thinx up this stuff??!!) Apparently you're having trouble fixing this problem ... I understand--I'll just use Edge or Chrome from now on. Sorry if I woke you.

ver: 134.0.1 Windows 10 Pro I have Firefox set to open filetype PDF in Browser. Normally I use IDM which automatically download PDFs, unless I press ALT key while clicking DOWNLOAD button, then it does not, in order to allow Firefox to handle the PDF.

Firefox presently does nothing. With filetype setting set to Open in Browser, Firefox Does nothing. If settings are set to Ask, it does not ask. The PDF filename appears at bottom of screen momentarily.

ver: 115.19.0esr Windows 7 Utl 7601 The exact same behaviour was also seen on a Windows 7 system running Firefox 115.19.0esr. PDF is also set there to "Open in Firefox". Again, when ALT pressed when clicking Download button, Firefox does nothing.

Is there a way to set a default zoom for the firefox pdf viewer? The Automatic zoom has no toggle, and all pages open up as HUGE and I have to manually choose the zoom %. This is tedious and takes up time as I open many documents a day.
