Firefox 136.0.1, Linux 6.8.0-55, have set Okular as default pdf application, however Firefox will not open pdf file when downloaded nor will it open the file when selecting Open File from the Download Icon on the toolbar. Only was I can get to file is to select Show in Folder option and open from within Dolphin.

I was having an issue with pdfs on firefox; all my pdfs were showing up as black. To fix that, I refreshed firefox, which solved the problem just fine. Unfortunately, once I did all my extensions stopped working. The page looks like this.

For most of my extensions, I can just solve this by getting rid of them and adding them again, but if I do that for onetab I'd lose all my stored tabs. How can I get this back?

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?

Firefox is not rendering/displaying charts (e.g. on Etrade), some graphs, and embedded pdfs (ex. on TaxCaddy--cannot see pdf files embedded into the web page). When I use Chrome, the problem goes away. I'm running 136.0.4 (64-bit) on Windows 11.

What can i do to fix this?

For the past YEAR or more, every time I choose to download a PDF (whether by saving a web page via file/print/save to PDF or by downloading an actual PDF via emailed link) my saved PDF has a padlock. I am forced to remove each padlock individually by adding 'users' under permissions. There is no way to do this for more than one file at a time.

This never used to happen in the past and I've made no changes to my PC or to my Firefox settings. I know it's a FF thing because if I save my own MS Word files to PDF there is no padlock.

Is there ANYTHING I can do to finally stop this and download PDFs without a padlock?

Thanks.

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

I'm viewing a pdf that seems to be made of stacked images. While viewing this pdf in firefox it has these black lines between images, as seen in attachment, these change slightly as I zoom in. These lines do not appear when viewing the pdf in brave, see other attachment.

Also, this happens both on my desktop and laptop that have very different firefox setups.

How can I fix this without fixing the pdf?

How could I even fix the pdf?

In Firefox, recently I am unable to download pdf documents. I get the message "download failed". If I request the same download using Chrome, I get the download immediately. But Firefox is my default browser and it's a nuisance. This only started in the past month or so.
