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.

I am using Firefox version 136.0.1 and we have multiple PDFs that are password protected (please see attached screenshot from Adobe Acrobat).

When the PDFs are opened in Firefox, it allows the user to add annotation/text/draw which we do not want to happen hence we added restrictions to the PDF. It seems to me that Firefox does not respect the security added to the file. How can I restrict annotations to the PDF or at least require password when the user tries to add text to it?

The following viewers/editors ask for password before you can edit them (expeted): - Chrome - Edge - Adobe Acrobat Pro

Thank you.

When I open a PDF in Firefox, a box covers the right half the page demonstrating the highlighter tool. It never leaves. It blocks half the page and prevents me from reading and/or printing. Please help. It's making my work impossible.

Hello,

I have a PDF that opens and displays correctly in Adobe as well as the Edge Browser.

However, when I attempt to open it in Firefox in Windows 11 it doesn't show the letter "i" - - - I swear I'm not making it up. I had a friend try to open it in her Firefox (Windows 10) the letter "i" is also missing.

I wish I could attach the actual PDF so others can test but I will add a screenshot to this message.

Regards,

Paul

As long as I have legitimate antimalware running, even with exceptions added for firefox, almost every single page comes up with one of the unique-to-firefox security errors rendering it practically useless. And the recommendation is to disable my antimalware? This is not an acceptable solution. I certainly don't trust Firefox to call the shots regarding my security over a reputable antimalware company. Especially when firefox is the only browser that has a problem. If you're going to to make yourself useless, you might as well let me access a page with a valid certificate and signature. Can we have an option to turn off your faulty security measures please?

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.

I've been using the firefox pdf viewer for quite some time and it's worked quite well. Within the last few days though I've developed an issue.

When I open a pdf it opens correctly for just a brief second (standard text, white background, nothing unusual) and then switches to something like the attached image (black background/ text and such). I have not changed anything that I'm aware of, though I did just recently install a new firefox update (136.0 64-bit windows 11). I didn't notice any articles or comments about this particular issue here yet, so figured I'd ask for some help.

Anyone know how to resolve this? Or other things I should look into?

Thanks for your time, Derek

How do I get the PDF viewer to work again? For years I have used the setting "save" to automatically download. Now I am unable to view them without going in and changing the settings to "open in firefox". I would like to continue to use the save setting without having to constantly change this back and forth. When I click to open the file, all it does it grey out.

So I download the latest update of Firefox. New feature: Edit PDF's in Firefox. Sounds great.

Click on the Try it Now link ... downloads PDF to computer. What? What happened to Edit in Firefox? What am I doing wrong?

When viewing a PDF, I selected some text, right clicked and chose the "Highlight Selection". The selected text was not highlighted. Instead, the "highlight" button on the top right corner pop up and the freehand highlight was triggered, while all my previous selection was lost.

I image this was not the intention of the "highlight selection", and I was also wondering if there is a shortcut for highlighting text in pdf.

I use Xero accounting software and used to be able to view pdf within the software up until the recent update. Now it just sits with a spinning wheel. I've found that if I change the setting within Firefox to open the pdf within Firefox the issue is fixed in Xero. But then all pdf's open in Firefox instead of the usual Adobe. This breaks other workflows within my organisation as I need to email the pdf straight away when I download it, so my Windows was set with Adobe as the default for opening pdf's but now Firefox has taken that over. There does not appear to be any way to email the pdf from Firefox other than to save it and then find the file and email it from there which is very time consuming. I don't know what has changed in Firefox, but please can you fix it. I see I'm not the only person with this issue.

When I am using the highlight tool in my firefox browser, the drop-down stays open and there appears to be no way to make it invisible. It takes up a chunk of my browser window so that I can't read the part of the pdf it's covering. Is there a way to make it go away while I am continuing to highlight in my pdf?

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
