I-Firefox Isithangami Sokwesekwa

Firefox shows a PDF invoice provided by my internet bank. The PDF is readable on screen but when I print it out, all the text is scrambled (see enclosed scan). What happens? I have to go the long way and download the document and read it with Adobe Acrobat Reader and print from there to get it right. Or I can use Chrome, from there it will print OK.

For the last several versions of Firefox, all attempts at PDF downloads fail. On rare occasions I can go to Save As..., get a dialogue box and save the file. But 80+% of the time it just fails and I have to go and paste the URL into Safari to get the file. Every time Ffx. upgrades I think this might get fixed, but it hasn't. I'm running AdBan and Do Not Track Me in both browsers, so that shouldn't be the issue. Please advise.

If I'm in Firefox and want to print an editable (to highlight) pdf page, I go to "Print" then choose either "Microsoft Print to PDF" or "Wondershare PDF element". What is displayed is never right. It may show the 1st page . . but not the rest; or nothing at all. I was going to try "Nitro Pro 12" but it appears that there is no way to install its "plug-in" now with Firefox.

    The end I want to get to is to have the ability, from within Firefox, to convert or "print" a pdf, that is editable, and will allow highlighting, from the webpage HTML.  It would be nice if it could be done, all at once right from the browser, without having to go through multiple steps - like taking a "screenshot" then uploading that image to some other site - which has also had unsatisfactory results (each "step" having the potential for some other unforeseen screw up or incompatibility).  I've spent a lot of time searching and can't find anything.
    Any help would be appreciated.

Firefox PDF reader is not showing watermarks.

People can see (and print?) my free samples minus the watermarks that are in them.

eg at lauriewilliamsmusic.com/composers/laurie-williams/auld-lang-syne/

Watermarks were put in by PDFill Free PDF Tools and always show up in Adobe Reader.

I never imagined that such a failure could happen until I was checking things today and saw it. Not good.

Just realised that this thing is asking about my browser. I'm writing this in Chrome but I have the latest version of Firefox.

I am running FF 77.0.1. This has been an issue for awhile however. In Options, under Applications/PDF, there is no Preview in Firefox option. I've tried quitting FF, renaming/moving handlers.json; but on re-opening the relevant section remains the same(action=0). I discovered about:config pdfjs.disable=false, previously it was set to true. Then in Options/Applications/PDF, "Firefox" is an option to open, and the action=3 in handlers.json, however the behavior of downloaded pdfs is the same (downloaded). (This is trying example pdfs from different sites). I've tried changing about:config security.cps.enable=false, no change. I've also seen a plugin to "fix content types" that shows up on this site, but it didn't change anything. From what I gather, action=3 should be Preview in Firefox, not Firefox, and all pdfs are being downloaded. Is there a way to fix this? Not seeing pdfs in browser is significantly annoying.

The settings are proper ; Text Only Zoom is unchecked & Minimum Font Size is None. However, the text is cut off in the sentences when PDF is opened in Mozilla. The same looks good in IE and Chrome.

I am currently using Firefox version 77.0 in windows 10. I noticed few things that when I try to open some of the PDFs it shows "This PDF document might not be displayed correctly" and just blank white page shows up (image included).

I use few extensions which I disabled them completely when I read PDF but still I am unable to access PDF. While same PDFs are easily readable by other browsers like Chrome or Edge.

Please let me know is it a bug or there is some settings to tweak. Thanks in advance.

I would like to use the Nitro PDF viewer plugin as I view hundreds of PDFs a week in my browser. Often, I will email the PDF with a quick link. Now that the ability to view PDFs in the browser is limited to the built-in Firefox PDF viewer, you will need to upgrade it's capabilities to meet the flexibility of the other PDF plugins that can no longer be used with Firefox. Nobody wants to be forced to save every PDF to their drive, and then go find it and open it in their 3rd party viewer to view it properly or email it off.

Please add an "Email PDF" button, as well as an "Open PDF" (with the default PDF viewer) button to the integrated Firefox PDF interface.

Thank you, Joe

I updated to FF 73.0.1 a couple days ago and now when I navigate to a PDF file, it no longer will Preview in Firefox. Instead, it goes to the Save File option.

I've tried setting it in the Options/Applications and all the other choices work fine except the Preview in Firefox.

So I'm trying to change my default PDF viewer to Mozilla, but it won't change from Edge to Mozilla. I have set these settings "Preview in Mozilla". Also, if I try to change my default PDF viewer in Windows, it won't even let me change to Mozilla, it just pop backs to Microsoft Edge. However, if I try to set my default PDF viewer to Adobe or anything other than that, that totally works fine.

I am embedding a PDF in an iframe like this:

           <iframe id="pdf_frame"></iframe>

I load the image using this Javascript:

       let frame = document.getElementById("pdf_frame");
       frame.src = pdfUrl;  /* URL of the PDF */

At night, my web page will be in a night mode (with a black background). I'd like to launch the embedded PDF viewer in night mode as well. Are there URL parameters to do this? Does the built-in viewer even support a night mode? I know that Acrobat supports a night mode.

I think my one sentence does it. I am using Firefox as my pdf browser. I click on a file in Explorer, then it keeps opening the file continually in Firefox. If I catch it in time, I can close firefox. If not, I cannot even use the Task Manager. I have to hold the off button until my machine turns off. Thank you for any thoughts on this. I believe it is a bug. WR/~ David

Essentially the same problem as https://support.mozilla.org/en-US/questions/982704.

Links in a PDF file viewed with the internal viewer in Firefox 38 (specifically 38.0.5) on Win 7 (64bit) do not open and are seemingly unresponsive. The PDF was created from the File+SaveAs PDF option in Microsoft Powerpoint 2010. The links are relative (e.g., test.mov, ../newdir/test.html as opposed to absolute like http://test.com/test.mov). Hovering the pointer over any of the links shows "resource://pdf.js/web/". Clicking a link results in no response.

On Internet Explorer (IE) 11, hovering the pointer over any of the links shows the expected (relative) URL. Clicking a link results in the expected URL opening.

Question 982704 noted in January of 2014, "It is already fixed in a future version of the built-in PDF Viewer...when Firefox 28 gets released in March..." Is it broken again, or is there an option which needs to be set either in Firefox or in the creating of the PDF in Powerpoint?

Plugins: Adobe Acrobat Reader is set to "Always active" Options/Applications: PDF are set to open with Adobe Acrobat Reader (in Firefox)

Before (1 or 2 weeks ago): some PDF opened directly in the browser. For others a dialog box appeared, giving me the choice to either save or open the file. If I chose to open, it opened in the normal Adobe Reader (that's still OK, but why do they not all open in the browser?)

Now: what I described above still works with the integrated viewer (i.e. when I change settings to "Preview in Firefox"). With the Adobe plugin, PDF that opened automatically in the browser still do, for the others I don't even get the dialog box. They are just being saved and that's it. How can this be changed?

I went to option/applications set pdf to open with reader in firefox but this is not working Whenb I have a PDF link it always open with Internet download manager

I went to about:config , reset the string: plugin.disable_full_page_plugin_for_types did not work

hlp please

Hi, I'm currently running version 63.0.1 , something has changed with my browser, previously when I clicked on a pdf file it would automatically open within the firefox browser. It's rather frustrating to me as a user of this great browser when a pdf file attempts to open using something other than firefox. I feel sure there MUST be some method to correct this issue. Thanks, David

The scrollbar is not visible in the PDF viewer. It is when I click on the right side of the window, but it's always a blind attempt since I cannot see where it is and therefore I loose the page I was reading. I have just updated to 62.0 but the issue is still there. I use Ubuntu 18.04.1.

- Fully updated FF + Windows 8 64-bit (9200) - Set up FF as the default program for PDF documents in Windows' Control Panel - Set up FF as the default program for PDFs in FF options

FF still asking me what to do every time I click on a link to a PDF file and the option "Do this automatically..." is grayed out.

Any fix?

Thanks

When I uncheck the option "allow pages to use their own colors..." in preferences, and view a PDF using the built-in viewer, all text in PDF documents appears to be printed twice with the default color (usually black) then printed again with my preferred color slightly shifted giving the appearance of all the text having shadows. I usually set my color preferences for pages to have a black background and a light gray text. This may be a bug.
