I am using Firefox 157.0.1 (64-bit) on Windows 10. When I browse papers on https://www.sciencedirect.com(https://www.sciencedirect.com) and click the "View PDF" button, the page that opens is completely blank. The same PDF loads normally in Microsoft Edge.

I have already tried troubleshooting steps: I cleared cookies for this website and disabled Enhanced Tracking Protection for [sciencedirect.com](https://sciencedirect.com), but the blank page issue still exists.

Thank you for your attention and assistance.

Ich öffne ein PDF File in Firefox. Er wird in Firefox angezeigt und sofort öffnet sich die Datei zusätzlich Adobe Acrobat. Das soll es nicht. Ich habe geändert: - in firefox im Menu download: PDF öffnen: Firefox - in Windows 11 Standard APP für PDF: Firefox - in Windows 11 Standard Browser: Firefox

Ich weiss nicht, wo ich jetzt noch die Einstellungen ändern kann, damit sich eine PDF Datei nur in Firefox öffnet und nicht automatisch nochmal Acrobat.

Hi,

I added some annotations to a PDF using Okular on CachyOS. When I open the PDF in Chromium’s built-in PDF viewer, the annotations appear in the correct positions, just as they do in Okular. I also checked using a few online PDF viewers, and the annotations display correctly there too.

However, when I open the PDF in Firefox, all the annotations appear in different positions than they do in Okular.

After the last Firefox update, I can no longer open download files (PDFs) from websites in Mac Default Viewer. I have tried the other settings such as open with Adobe, Ask, etc., but they continue to only open in the browser. For work, I download hundreds of documents from a county site, so having them open in my default viewer when I click the link was very useful for a productive work flow. I have tried to open files with my viewer from other sites, but it fails with those too. My tech team tried to help but seems to be a Firefox issue. Settings - Downloads - Files and Applications - PDF - Use Preview (or anything else) is not working. Firefox 157.01, Apple M2 Pro, Tahoe 26.6.2.

Pressing print/pdf button for screenshot then pick the folder destination documents then press save and what it's used for is decrease the size of the screenshot with pinching the screen then retake the screenshot of desired smaller size however for the first time it has an error in documents folder the says "can't open pdf" and then I tried the 3 dot menu in upper right corner to use an app to open it up and I went through all of them and nothing works

I hope this is a simple setting issue. I believe I have tried everything others have recommended.

When I open a PDF I get a black background and a grey block. One for every page in the PDF.

When filling forms using the nightly build `148.0a1` on ubuntu 24.04, all date fields seem to default to `mm/dd/yyyy` when I want to use `dd.mm.yyyy`. I cannot seem to find anywhere in firefox settings to change this default, and this makes it impossible to fill some forms correctly (as in the case of e.g. government forms in Germany, only one date format is accepted)

Is there a setting in Firefox where any PDF's last read position is saved? If not, will this feature be available in the future? Note: Edge browser has this feature.

Version 157.0 (64bit) has updated and resizing has caused issues. Previously, on my laptop screen, when I was viewing pdfs in browser I would navigate to the Tools dropdown and view the document properties at the very bottom of the dropdown. Before the update, all of the menu items fit without needing to scroll (when the window was fullscreen). Now, i must scroll in the dropdown to access Document Properties. The update resized the menu, making it longer and now it overflows. Please consider resizing back to original size or allowing users to adjust the dropdown menu.

When I set Firefox as my default pdf viewer and click in Macos Finder to open multiple files nothing happens. Clicking on one file it opens it fine. Used the "Troubleshoot menu" to disable extensions and disable custom settings, same behavior. At one point I disabled "hardware acceleration" and it actually worked. Then it stopped working, not sure why. Any ideas?

Thank you.

Firefox just updated to 157.0 and will no longer open PDFs in a default viewer even when I change the settings. My setting say they are set to open in Mac Viewer, but continue to open in browser. I even tried to set it to open in Adobe still opens in my browser.

I used Quickfile for my accounts. Until the most recent Firefox update, I could create invoices within the software which seems to use Firefox to create them. this no longer works - within firefox it looks like it is creating the file, but doesn't seem to create a file that is able to be opened. Therefore I am using the Print Preview within Firefox, and selecting Print/Save to PDF and this works ok, but is another couple of clicks which is annoying.

Whilst Firefox may not be at fault, the issue isn't there on other browsers and it happened with the big update last week.

I use Firefox to read a lot of PDFs. Some of the documents have their own internal sections embedded into them. Because of this, Firefox PDF organizes the page numbers in a strange way. Instead of just page 1 through page 112, each section will have its own numbers starting over from 1. Thus, when I try to skip to page 3, it doesn't actually bring me to page 3 of the entire document, it brings me to page 3 of whatever section I'm in.

A large part of my job is digging through documents, and I don't have time to try and figure out which section of the document I'm in. I need page 3 to be the actual page 3. And I refuse to go back to Edge or Adobe.

I know there's a way to fix this in about:config because I've done it before on a previous computer, but I recently got a new computer and all my settings are gone. How to I turn on just regular page numbers in about:config?

The "New" PDF previewer sucks, can we revert to the old one that actually worked ?! It's a "Preview" , maybe don't try to open everything and BE a PDF program inside the browser, the whole point is to get a "Quick" look so you can decide to open , or, delete it ! This is as Bad as MS Edge trying to take over for PDF's , Revert this change, or Give us a way to choose to use the old way ! Thank you.

Firefox 157.0 (aarch64) macOS Tahoe 26.7.1

When I click on the link to a PDF to open it in Firefox and click on the Save icon in the file viewing UI (see attached image pdf-save-icon.png) to save it to my local device, no File Save dialog box opens and nothing happens.

If I right click on the link to the file instead of opening the file, the file is saved silently to the Downloads folder with a name that ends in .pdf.part (see attached image filename.png). That typically indicates a partial, failed download, but in this case, if I remove the .part from the filename, the result is a viable PDF.

The "Report Broken Site" is grayed out in Firefox. I tried all the fixes offered in Firefox. I checked my data settings in Firefox to make sure that Mozilla was included and could receive data. I cleared my history. I restarted my computer. No help. I restarted Firefox. I cleared my history. I restarted my computer. No help. I replaced Firefox. I restarted my computer. I cleared my history. No help. I tried the fixes offered on Google. I cleared my history. I restarted my computer. No help. Nothing seems to be working. Is there any help out there?

This is what I get on the Chase site in question when I look to see my statement. @ secure.chase.com/web/auth/pdfviewer?docKey=21743136-8056-4785-a682-0fd001b36caf&sor=STAR_MS&adaVersion=false&csrftoken=fdaab518f892e949fe5eef858b07f7eb 3 The page where the statement is supposed to be visible is blank.

It downloads the statement instead. I have been able to see the statement online previously, but now I can't. Would like to be able to see it.

Some of our property reports go to tenants as PDFs for a signature, and a few of them only use Firefox, so I'd like to point them to the built-in PDF viewer rather than asking them to install anything.

If someone signs with the draw tool and then saves with the download button, does the signature stay in the file and show up properly in other readers like Adobe Acrobat? And is there a better tool in the viewer for signatures than freehand drawing?
