Firefox Community Forum

I have looked at some of the comments about Firefox automatically opening pdf docs. Myu concern is twofold. Most importantly the password in the doc is somehow being overriden; that is a severe security issuen for me. Destroys the whole concept of security. Makes me very uncomfortable and may discontnue using Forefox after more than 15 years. Secondly this caught me by surprise; it only occurred for the first time this morning. How can i overcome this to prevent Firefox from performing merely as a browser?

On one PC, pdf files [Type of file : Firefox PDF Document (.pdf)] display with a PDF icon but on a second PC, pdf files [Type of file: PDF File (.pdf)] display with a Firefox icon.

What changes are needed to have pdf files display with a PDF icon on the second PC?

I go to various websites, in this case https://go.valcom.com/EZ-GW1Rezipinstallationmanual (as well as other pages on this same site) and when I try to look at a manual or specs in pdf format, I get a blank screen and the URL looks like the go. and everything after the .com are grayed out. These work fine in Edge and Chrome. This also happens in Troubleshoot mode. No hardware or software changes on my desktop.

Download Issues My downloads have stopped displaying. Each page of a download is now just a black screen. Any advice as to how I can restore them?

When I try to open a pdf on a certain site I get the pdf, but there is an overlay of a pencil editing a ghost document. How can i get rid of this overlay? I've tried everything.

Hi Firefox Team,

Please assist.

All pdf files show all pages blank. It affects both those newly downloaded in Firefox and those I have stored on my PC and open with Firefox. I think this started from when the latest Firefox update was installed this week. I am up to date on Widows 11.

Well, there is a bug with your downloading files configurations that REALLY ANNOYS me, which is, i want to always select where to save my downloaded files, no problem with that, i just set all configurations to "always ask", but sometimes, especially for pdfs, i want to just open them, without the need to save them to my computer, so the only one i have set as "open with firefox" is the pdfs, and if i want to download them, i just do so by clicking the download button on the corner. BUT, with this configuration, if there is a button to download a pdf, without opening it previously, it will skip the "ask where to download" pop-up, which is a pain in the ass, as usually want my stuff in specific folders, not the general downloads one. And even iff i set pdfs to "always ask" and then chose to open with firefox, it will automatically download it (???????) to the downloads folder, and then open it from my pc, even tho it could open it from the file in the server, which is what i wanted. I just switched to firefox, please fix this awful feature and dont make me find another browser.

When I click on a PDF link it will auto download the PDF but then if I click on the same link again it opens it inline. I want it to always open inline and if I wish to save it I'll manually do that.

I've looked around and I found this that mentions using browser.download.start_downloads_in_tmp_dir and browser.download.open_pdf_attachments_inline. While setting the downloads to be in the tmp dir is nice for not clogging up my downloads it still doesn't solve the issue of opening and not saivng. The setting for opening pdf attachments inline sounds like it should fix it but still every time the first time I click it, it starts downloading it.

Is there any other setting that could stop this or some reason why those settings might not apply in all situations?

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

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.

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.

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.

I am currently revising for professional qualifications and the PDF study manual I am using is extremely large.

I have seen tutors be able to use the document outline on the left sidebar to be able to filter through different chapters.

However, I do not have that option - I only have the option to view page-by-page which is not very helpful.

How can I get the document outline to show a chapter-by-chapter outline?
