Since the update to Firefox a few days ago, I am no longer able to view PDFs in the browser. They still open, but they show up as blank pages. Is there a way to fix this or to revert back to the previous version of FF?

Thanks.

On loading some documents a popup appears asking me to "Sign on the dotted line". This shows a pencil making a signature. I am unable to move or delete this popup and therefore cannot read the document fully. I can't print it either as the popup obscures the printer instruction area. I would be very pleased to know how to remove/block/disable this uncalled for obstruction

Editing a PDF is a great feature. Entering a text in Hebrew results in a PDF that, in some viewers (like your own) , the text disappears. When opening the file saved in Adobe Acrobat, it's fine.

I'm having a problem with Firefox when opening PDF files. The electronic signature appears inaccurately, making it difficult to complete tasks using that signature. Please improve the quality of the simple electronic signature and make it more accurate so I can finish my remaining work.

I am writing the following sentence in html: <a href="https://www.users.no/ingehelland/Desktop/QDT_article.pdf">QDT_article</a>. Firefox refuses to open the file

Hi everyone,

I’m running into a frustrating issue where Firefox is opening PDFs in two places at once.

The Problem: When I click a PDF link, Firefox opens the file in a new tab (internal viewer) but also launches the standalone Adobe Acrobat app to display the same file. I only want it to open in Firefox.

Details: - Settings: My "Applications" setting for PDF is currently set to "Always Ask." - The Glitch: Even when I manually select "Open in Firefox" from the prompt, Adobe Acrobat launches anyway. - Timeline: This started happening 2 days ago without any manual setting changes (I think it might be after a firefox update? I might be mistaken)

- Troubleshooting done: I have tried toggling the action to "Open in Firefox" directly, but the dual-launch behavior persists.

Thanks

Up until a few days ago I was able to preview yahoo mail attachments (e.g. PDFs) before downloading them. I don't know what may have changed, but I don't recall doing anything on my end. Any suggestions or advice on what settings I should consider changing greatly appreciated. M

Chrome based browsers display dark pdf correctly. Firefox does not. see attached images. all extension are disabled.

Why has Mozilla decided to COMPLETELY IGNORE security settings applied to PDF documents? I have a number of PDFs secured so as to prevent the ability to print or copy text. When opened with Firefox, all of these settings are ignored.

When I try to download my credit card year end summary on my MacBook Air I get this message, "Your browser is unsupported and unable to display PDFs" I have done this for years and never had any trouble. I checked for Firefox updates for IOS and it says Firefox is up to date. It also says I am on the esr update channel. Why would this suddenly be a problem? How can I fix it? Thank you for any help or insight you can give me. PS I am old and no longer tech savvey. Technology has left me in the dust! So please be as untechnical as possible in a response if I am so lucky as to receive a response.

I am unable to open PDFs from my bank. I tried the following steps;

Change Default PDF Viewer:

   Go to Firefox Settings.
   Scroll down to the Applications section.
   Find Portable Document Format (PDF) in the list.
   Change the action to Open in Firefox or Preview in Firefox.

Clear Bank Cache/Cookies:

   Go to Settings > Privacy & Security.
   Select Cookies and Site Data > Manage Data.
   Search for your bank's website and clear its data.

Hello,

I can't save and download a modified PDF file.

To put it simple: I open a PDF file on Firefox; Rotate it clockwise; Open the Tools menu (»); Click Save; The saving window opens; I save the file; When I open it, the file is as at start, before rotating.

Windows 11 25H2 26200.7623, Firefox 147.0 Thank you for helping.
