I'm begining to regret installing v146.0!

One of the most useful features of Firefox is the PDF editor and with this update, I've found that after annotating a PDF with several text boxes, clicking the text box icon (as shown in the attached screenshot) does absolutely nothing and it is impossible to enter any further text. The only way out of this is to refresh the pdf (after saving otherwise all changes will be lost) and then starting all over again only for the error to repeat itself making the editor almost unusable. Would really appreciate knowing how to work around this especially since to make my notes clearer, I change the color and the font size which is all lost everytime I have to refresh the PDF :-(

Incidentally, why are there so many updates? I prefer stable software that works rather than 'new features' that I never use!

Finally, Firefox used to have an amazing facility of making the Firefox private browser the default browser for Windows 10 but this was removed some years ago and can only be reinstated by changing registry keys. Everytime there's an update, these registry keys are overwritten :-(. Why was such a useful feature removed please?

Thanks in advance.

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 am no longer able to open in Mac Preview or save when hitting Command + P, then 'print using system dialog'. It will only print instead. For instance, I save certain web pages as PDFs using the print dialog and now it will only print when trying to use either the save or preview options. Command + P, print using system dialog, then I choose either save as PDF or open in Mac Preview, but as soon as I do one of these it will only print. I am able to use save in the drop-down list of printers, but I need to be able to open in Mac Preview.

I'm trying to use Firefox to fill out my tax forms, but while I can save them and view them with Firefox, they're blank when I open them with Adobe or print them. This is, to say the least, NOT USEFUL. What is happening?!?? I'm using Win10 and the latest version of Firefox, and I tried it on an old Mac with the latest version of Firefox as well.

For the past YEAR or more, every time I choose to download a PDF (whether by saving a web page via file/print/save to PDF or by downloading an actual PDF via emailed link) my saved PDF has a padlock. I am forced to remove each padlock individually by adding 'users' under permissions. There is no way to do this for more than one file at a time.

This never used to happen in the past and I've made no changes to my PC or to my Firefox settings. I know it's a FF thing because if I save my own MS Word files to PDF there is no padlock.

Is there ANYTHING I can do to finally stop this and download PDFs without a padlock?

Thanks.

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.

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

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.

I have a question about using Firefox PDF Editor. I copied some text from a PDF document that is on my computer, by highlighting the text and then hitting Ctrl+C. The text copied onto my clipboard OK. Then I opened a blank PDF document in the Firefox PDF Editor and tried to paste that text into the blank document, but I wasn't able to do so because when I right-clicked on the blank document and then clicked on "paste", nothing happened. This apparently is because the word "paste" is faded-out in the drop-down menu (i.e., it does not appear in prominent bold print). Google's Artificial Intelligence seems to indicate that the technique I used would work (see screenshot which I've uploaded). But it didn't work, so can anyone please tell me how can I paste text into that blank document?

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?

Starting a couple of weeks ago I haven't been able to open PDFs in my Firefox browser. Although there are other pdf viewers, Firefox has features that I use that the others don't. I've tried all the various ideas I've found elsewhere online but none worked. I submitted a ticket to our IT helpdesk, but they say it's a Mozilla Firefox issue. The error message isn't helpful at all, considering there is no web server involved.

I get the error below:

Access to the file was denied

Firefox can’t connect to the server at local file What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

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

I often save to PDF or mark text then transfer it into a document. Firefox renders many letter combinations as ligatures: ff, fi, ffi, fl, and more. I don't want ligatures. The cures proposed have involved forbidding pages to use their own fonts. Is there another way?

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.

When viewing pdf files created from MS Word (.docx) documents and sent to me I see white lines across some images but not all. This happens with Firefox on Windows 11 and linux mint (various versions). It is present on the images from the file as received and after uploading to a website. The images are OK if viewed using Opera or other browsers but the same problem is present on Thunderbird. The file below has the problem on 2 images when viewed on Firefox. https://www.kass.org.uk/Documents/NewsletterFrom251114/20260304%20March%20Newsletter.pdf I have caused the writer of the article a lot of trouble because I blamed her file which seems to be OK. Can you help? Thanks Brian

Hello,

I can't save and download a modified PDF file.

To put it simple: I open a PDF file on Firefox; Rotate it clockwise; Open the Tools menu (»); Click Save; The saving window opens; I save the file; When I open it, the file is as at start, before rotating.

Windows 11 25H2 26200.7623, Firefox 147.0 Thank you for helping.

I often open PDF links in Firefox. I can choose to open the PDF in a Firefox tab. If I leave the tab open and restart my computer, or look for that tab sometime in the future, I often see a page that says File not found (see picture). Somehow the page is being cleared out of the cache. Not sure if Firefox is doing this, Windows or some other program. Any ideas to keep these pages so I can see them in the future?
