Firefox Tekoha Aty

I am using the FireFox PDF Editor to annotate a PDF, however, no method of me saving the document (whether that is save as, or save as PDF) will allow me to save any annotations on the document. If I try doing save as PDF, the preview shows up as blank sheets of paper, when I click "save as" it only saves one page of the 31 as BLANK. If I try doing normal save as, the saved file is un-annotated.

Please help... thanks

Recently, I am unable to open PDF's on Firefox. When I go to another browser and access the same site (such as a bank) I am able to view the PDF. I have tried some of the suggestions regarding extensions etc, but nothing seems to work. Is there a solution? Thanks, SVS

Firefox screws up showing .pdfs. The first view is fine but scrolling seems to overprint the first view without erasing it, if that makes sense, sorta like a double exposure. I can't get a screen cap either, which might just mean it's not a firefox issue at all, but I can view and screen cap .pdfs from any other application. I'm running Debian 12 up to date. When I need to view a .pdf I use Chromium, but I do prefer Firefox.

Dear Firefox Support Team,

I am encountering an issue where PDF files fail to display properly in Firefox, appearing as blank pages. This problem persists across multiple PDF documents, suggesting a potential browser compatibility or configuration issue.

Request: Please investigate this behavior to identify the root cause (e.g., rendering engine, plugin settings, or recent updates). Adjust Firefox’s default PDF handling settings or implement necessary fixes to ensure proper PDF display.

Additional Details:

• Firefox Version: All
• OS: Windows & Mac
• File link: https://res.mdpi.com/data/pharmaceuticals-18-00847-v4.pdf
• Steps to Reproduce: Open any PDF file → Blank page appears.

This issue impacts productivity and user experience. Kindly prioritize resolving it or provide workarounds. Thank you for your attention.

Best regards, Mia Yu [email removed]@mdpi.com/[email hidden]@qq.com

Lately, whenever I try to open a PDF from a website open in Firefox, the tab crashes and the PDF does not open. An error stating that the Windows file-dialog has crashed is displayed at the top of the tab. I tried to attach a screenshot of the error but that action only generates another error.

This condition does not occur when I try to open the same PDF from the same website open in either Chrome or Edge, the PDF opens properly which leads me to believe the problem is in Firefox and not my Adobe installation.

Thank you

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?

Every document like the below one does not display in firefox esr 115:

https://support.hpe.com/hpesc/public/docDisplay?docId=c01081836&docLocale=en_US

I get an empty pdf viewer frame. Also the debugger shows the following error;

Uncaught TypeError: Promise.withResolvers is not a function

Is there some way to overcome this problem? a future release of firefox esr?

Hello: recently I decided to ditch expensive PDF Converter apps for my desktop pc as overspecified for my purposes. To date, I haven't found any guidance to use the Firefox Easy PDF Converter - usually required to convert Lotus Word Pro or MS Word text documents to pdf format. As a second request, can it be used to reverse convert e.g. pdf to docx etc. I have already added it to my Firefox app, but can't go any further. Thank you for helping. Geoff Pickerell (UK)

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.

Firefox 137.0.2 64 bit

I've recently set up on a new desktop running windows 11.

My previous setup had windows 10, but the same version of Firefox.

In the past, when building web pages in php, I'd always used Firefox to preview the html elements of pages offline. I've not used a testing server on Windows as I'd rather test the PHP elements on the live server. Firefox was just for testing the html / css design elements, which it worked very well for.

Now, on my new computer and windows 11, when I try to open a php page offline with Firefox I get a window asking me what to do with the file - "open with" or "save file". When I choose "open with" and choose Firefox, Firefox opens up another tab with the address of the file in the address bar, but no content below, and then another window pops up asking me what I want to do with the file. This goes on indeffinately if I keep clicking "open with". There's no issue with the files I'm trying to open as I can open the exact same files on my win 10 computer with the same Firefox version and the display just fine. What's going on?

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?
