Hi All,

I've set Firefox to open PDFs in the default system application (I'm on Linux, KDE, Firefox 146). With previous versions it worked fine. Now, it won't open the file; instead it shows a popup that I have to click to open the file.

Is there a setting I can tweak to get the old behavior back?

Thanks

I'm viewing a pdf that seems to be made of stacked images. While viewing this pdf in firefox it has these black lines between images, as seen in attachment, these change slightly as I zoom in. These lines do not appear when viewing the pdf in brave, see other attachment.

Also, this happens both on my desktop and laptop that have very different firefox setups.

How can I fix this without fixing the pdf?

How could I even fix the pdf?

Firefox is not rendering/displaying charts (e.g. on Etrade), some graphs, and embedded pdfs (ex. on TaxCaddy--cannot see pdf files embedded into the web page). When I use Chrome, the problem goes away. I'm running 136.0.4 (64-bit) on Windows 11.

What can i do to fix this?

Every time I try to view a pdf file on Firefox I can view the file but in the lower right 1/4 of the screen I get a graphic of a page with shaded areas representing lines with writing on them. There is a type of pen cursor moving along the line.

This happens with different pdfs - from the internet and from my saved files. This doesn't happen on another computer with Firefox.

I've deleted and redownloaded Firefox an number of times, also tried troubleshoot mode - no improvement. Virus scanned, restarted a number of times.

Pdfs work on edge and chrome and reader with no problem.

I have a screenshot.

Any Ideas? Thanks

When printing a PDF with custom page ranges, the footer text in the print preview (see image) does not match the actual page. As shown in the example image, if I want to print pages 2-16, the preview indicating page 4 is actually page 5.

So, if I want to print with a very custom range, such as 2-4, 6-10, 12-14, 16, it will be very confusing and will take longer to adjust.

And I also print custom ranges like this very often for daily tasks. I’m not sure if this is a bug or just a minor adjustment needed in Firefox’s coding. Thank you in advance for your help.

Your browser needs immediate attention! I have windows 11. When I visit websites via Firefox and click on a link that takes me to a document, a large pop-up on the lower right side of the screen appears blocking half the page and preventing me from downloading or printing it. The pop-up depicts a cartoon-letter with a highlighter pen traversing its cartoon-text, below which is an enthusiastic missive stating (and I quote): "Now you can highlight your PDFs! With our new highlighter tool, you can read and edit PDFs in one place." Because of this infernal nuisance, I cannot print or download web pages. This has been going on for WEEKS! (That pop-up is USEFUL?! Who thinx up this stuff??!!) Apparently you're having trouble fixing this problem ... I understand--I'll just use Edge or Chrome from now on. Sorry if I woke you.

Every time I open a file that is downloaded the box showing info on the highlight tool comes up and then I have to hover over it and hit escape............I do not want it to open at all so how do I stop it..............

Is this an extension on the browser ? Do not see how it functions... Many Tks

While using Dext there is a visual of the uploaded pdf file. Now there is a notice that my Firefox settings need to be changed. Dext does not have instructions for Firefox and I have not yet located the spot in settings to adapt for this. Looking for directions.

Hi, when I work in Xero, the pdf documents will not open. Firefox is up to date and I have wiped all cookied and history. Is there anything else I need to do please?

Thanks Amanda

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?

Hello Mozilla Support Team,

I have been using Firefox for a long time, and recently I upgraded my Windows system. Before the upgrade, I had set Firefox to open PDFs directly in a PDF Reader other than Firefox’s built-in PDF viewer, and it worked perfectly. However, after the upgrade, Firefox now shows the "Opening when completed" message and opens PDFs slowly, instead of opening them immediately in my chosen PDF Reader.

I have checked the settings, cleared the cache, refreshed Firefox, and even tested with other software, but the issue persists. The settings for handling PDFs are still the same, but they don't seem to work as they used to.

Can you please assist me in resolving this issue? Any help would be much appreciated.

Thank you

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.

Hello all,

I know this feature is brand new and awesome! I have a question about the statement below from the FAQ.

What does the statement "When editing with Firefox, your documents generally stay on your local device" mean? I am just wondering about the "generally" portion.

I sometimes have to edit sensitive documents and want to make sure that this editor is a viable option. Will there be a prompt if the file has to be uploaded to a server?

Just some security concerns.

Thanks in advance for your help.

Mozilla/Firefox is my browser. Lately, every time I am on a website where I need to open a pdf document, like a bank statement I want to download, a pop-up appears that advises me to sign on the dotted line or anywhere and shows a little pen writing something. Underneath is this sentence: "Draw, type or upload your signature, then place it exactly where you want. Save your go-to signature for next time."

Where did that come from? It blocks my view of the document and if i try to capture it in a "screenshot" nothing appears. Is this a Mozilla/Firefox thing or a (Acrobat) pdf thing? And what can I do to stop it?
