Firefox Community Forum

I have Firefox set to always ask about how I want to open/save PDF files. Within the past couple weeks, I've encountered an issue with opening PDF files. When I click on a PDF and select "open with Firefox," the PDF opens in a new tab on Firefox, but it also opens in Acrobat. When I select this option, I just want the PDF to open in my browser, and I cannot find a way to stop it from simultaneously opening in Acrobat.

I have set the setting for PDF files to Always Ask. When I select the "Open in Firefox" option from the dialog, it opens the PDF in a new tab in Firefox and ALSO launches Adobe Acrobat and opens there. I have not seen this bizarre behavior before today. How do I fix it?

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

In February this year I started having an issue with reading pdf formatted statements from my bank' (bank and personal information removed). Initially I thought it was some change at the bank so I sent the letter below to my bank.

Further experimenting with Microsoft Edge and Firefox leads me to believe the issue may be with recent changes to firefox. The attached jpg file shows the problem, though not a solution.

I would be curious to know if there is some (new) setting in Firefox to correct the problem.

re: document access on site

You have evidently made some changes in your account display and I have to tell you there are issues with it.

Previously the account document came up as PDF. Today I accessed the current statement and immediately noticed the change in display format.

I usually do two things here. First I print the document. The print button worked as expected. Next I SAVE a copy for future reference. The download button DID NOT WORK.

I had to use the print save to file function. This is where I found the problem. I saw this when I checked my print queue as well. Instead of PDF the document is now PDF.js viewer.

I have to ask why you went to java script when the original PDF format worked properly every time?

On the plus side, my pdf viewer still reads the saved file. It is the unnecessary print to file step to which I object.

I am not at all happy with this change and would encourage you to return to the previous process. Since it was NOT BROKE I am at a lost to understand WHY YOU FIXED IT.

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.
