Hi Firefox Team,

Why suddenly today there's no PDF preview for all PDF file sent or received on browser (i.e whatsapp web) Attached latest screenshots

Please assist.

Regards, Novie

I am an academic. I use Canvas. When I am in Canvas and I try to open a document in it from Firefox, what I get are solid black pages. I do not have this problem with Canvas in Chrome or in Edge. I really don't want to use those Browsers. I actually have this problem with every PDF I try to open from all sites. This is a recent problem. But if I cannot correct it, I will have to use other Browsers.

Hi, I am having an issue in mobile on iPhone 13 mini where I am trying to view a PDF (a bill so I can’t share the link) and it just opens to a about:blank page that says:

“Your bill is almost ready. Please wait.

Are you using a Chrome browser? Check your browser’s Downloads folder for a PDF of your bill.”

I wait and nothing happens. When I try in chrome it opens immediately in another tab (and doesn’t go to the downloads folder funny enough).

It isn’t in my downloads folder here either.

I don’t think it’s the site since it works in chrome.

I tried turning off pop up blocker, clicking the link again, and it didn’t change anything.

I also notice it is labeling the blank page as an insecure connection. It is from my city electric company so that wouldn’t be likely.

Thank you

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)?

this is supposed to have a QR code, but it does not load. I have attached a still screenshot below.

I also cannot upload images using Firefox to Messenger. The large purple image is a result of an upload, but it should be a picture of a woman saved from Krita.

I tried a setting called "Refresh Firefox" and that fixed it but only for less than a day. whats going on?

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.

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.

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?

Whenever I open up PDFs within the Firefox browser, they have a black background and the text and images do not appear. I can copy the text and images out of the pdf and into a word document and it works out fine. Also opening it up on other applications works out fine. Attached is what happens when I open up a known working pdf in Firefox. The browser version is the current version, 135.0.

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.

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

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?

I am using Android 14 and Firefox for Android version 134.0.1 (Build #2016067655).

How do I edit PDF files in the Firefox Android app? I chose the Settings category at random when I entered this post because I couldn't find one that was applicable to the question.

I did a lot of searching in the Firefox Android Community and Firefox Android Support areas, as well as Internet searches but I couldn't find anything that was specific to Android.

Thanks!
