I don't know why, but every time i open a pdf with the firefox pdf reader i get this kinda grainy view of the pdf. If i do the same with google is all good. I really don't know what to do, can you help me?

Hello... currently when I try to open a PDF from the internet, I cannot open it in Firefox. Specifically I have been adding PDF files to a FB page, but cannot open the document when browsing in Firefox. I can open it, when using EDGE.

When I try to open a pdf on a certain site I get the pdf, but there is an overlay of a pencil editing a ghost document. How can i get rid of this overlay? I've tried everything.

I am attempting to read through the ARRL Antenna book (https://home.arrl.org/action/Store/Product-Details/productId/2014032576), which is a series of locally stored PDF's with links to separate PDF's of each chapter. In Firefox, the bookmarks resolve to the currently open file, rather than the appropriate file, thus not working (see "Firefox_Incorrect_Behavior.png"). In Adobe Acrobat Reader, the links resolve to the correct chapter PDF in the <Program Files (x86)>/ARRL Antenna Book 25th Ed/ARRL Ant Book 25th Ed. Content/ folder.

I closed a PDF file but can not move it to another folder. Windows says it is open in firefox. I closed firefox and it still says it is open in firefox. I even restarted windows and it still says it is open in firefox. How do I get firefox to close and release the file?

hi team, recently i can not open any PDF when i am in gmail using Firefox Browser is updated to latest verison, i have also check settings under application and whatever i choose, when click in PDF in my gmail, i can not open it directly, i need to go right click on it, open in new tab, then it downloads to my PC and open in new tab?. stupid isnt it? i have tried many settings and nothing seems to be working, any chance that i can just click on PDF and it opens in new tab or my Adobe app, without download it to my PC, cause sometimes i just want to see wtf is the attacment...

Hello. I have a question. When I scan a PDF file in Firefox, it opens in a new window. Why? I don't mind it opening in a new tab, so I would prefer it to open in a tab.

Hi everyone,

After enabling `privacy.resistFingerprinting = true` in `about:config`, I noticed that Firefox’s built-in PDF viewer (`pdf.js`) is always displayed in **light mode**, even though my system and browser themes are both dark.

I understand that RFP forces `prefers-color-scheme: light` to prevent fingerprinting, but this also affects internal components like the PDF reader. Unfortunately, the PDF viewer doesn’t provide a manual dark mode toggle.

Is there any **official or safe workaround** that allows keeping RFP enabled while still having the PDF viewer use dark colors?

Thanks!

Using Firefox 143.0 on Ubuntu 24.04, when loading PDFs into the browser window, the PDF does not get properly rendered. Instead, when scrolling part or all of the PDF just show the desktop or windows behind Firefox. This usually happens after opening several PDFs and then keeps happening until I restart Firefox. Is there an issue for this extremely annoying bug?

On one PC, pdf files [Type of file : Firefox PDF Document (.pdf)] display with a PDF icon but on a second PC, pdf files [Type of file: PDF File (.pdf)] display with a Firefox icon.

What changes are needed to have pdf files display with a PDF icon on the second PC?

I have a pdf document with live hyperlinks to websites. However, when I click on them, they open in Edge and not my default browser Firefox. Any suggestions? Have set default browser to Firefox and default PDF to Acrobat reader.

I am a Dropbox user. I have until recently been almost strictly a Google Chrome user. The PDF seamless behavior I have been seeing in Chrome is like this: 1. If I click on a search engine result for a PDF, I see the PDF opened in the browser. 2. If I click on Download at Dropbox, the PDF is downloaded to my PC.

On installing Firefox, the behavior I saw was like this: Whether I clicked on a search engine result or Download at Dropbox, I saw the PDF opened in my browser.

When I changed the Action for Portable Document Format (PDF) (application/pdf) and Portable Document Format (PDF) (application/binary)to "Save File", the PDF downloaded to my PC. But so did search engine links.

I seem to have fixed the issue by making my settings like this: 1. Action for Portable Document Format (PDF) (application/binary) to "Save File" 2. Action for Portable Document Format (PDF) (application/pdf) to "Open in Firefox"

Fingers crossed. ??? I was wondering why it wasn't set up this way on installation.

I am a magazine editor right on deadline and as my Firefox inisted it must be updated I endeavoured to do so and now it will nor allow me to open up and forward any pdfs.Please help.

I'm trying to use Firefox to fill out my tax forms, but while I can save them and view them with Firefox, they're blank when I open them with Adobe or print them. This is, to say the least, NOT USEFUL. What is happening?!?? I'm using Win10 and the latest version of Firefox, and I tried it on an old Mac with the latest version of Firefox as well.

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?
