Firefox Support Forum

Up until a couple weeks ago right clicking on a pdf and selecting to take a screenshot was doing just that - allowing me to take a screenshot of the pdf in the page. Since then whenever I try to do the same, I get an error saying that this is not a standard web page. Any advice?

Since updating to Firefox 36.0 (OS 10.9.5), PDFs no longer preview in Firefox: I'm prompted to download and save them -- even though in Firefox Preferences, the default selection reads: Preview in Firefox. Help, please.

I cannot open pdf files in Firefox. (I can in Chrome). I tried Menu - Preferences - PDF - Use Adobe Acrobat Professional. Also tried the same with PDF Browser Plugin 2.4.4 Clicking on a PDF link just opens a blank page.

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.

A weird one. I'm using Windows (7 or 8.1) and Firefox 40.0.3 – some setting must be screwed up.

When I click on some links on The Australian news website, it goes to that page, and automatically opens an associated PDF. This is a recent problem, on both my computers.

How can I stop this?

Thanks

For some reason, Firefox is now not displaying parts of the page correctly. I've noticed this mostly in my Wordpress Jetpack stats, but as I've gone around the web, it's been doing the same with PDFs as well. Videos and regular images are fine.

Here are some sample images. These are supposed to be JetPack stats, you should see line graphs, but it just looks like you changed the TV channel to a non-operating signal.

Here's what I see on a PDF: http://queenoftherandomjob.com/Bernie.jpg And the actual link to the PDF: https://berniesanders.com/wp-content/uploads/2016/01/Wall-St-Letter-1.pdf

I spoke with Jetpack and they said it definitely was a browser issue...I have checked in Safari and Opera and everything is rendering fine there. PDFs, Wordpress...no issue.

This issue started just last week, and I haven't installed or changed anything. Everything was fine in the morning, and then in the evening, it went all wiggy. I do not have Avast anti-virus (this seems to be the culprit in other people's issues,) and I'm on a Macbook. I have uninstalled and reinstalled Firefox, cleared the cache, etc. I'm still having issues.

If anyone has any advice, I'd really appreciate it! Thanks!

Hi,

I have one problem.

In firefox v.41, when I previewed a pdf, if the pdf had a links inside, there was no problem, but from I updated Firefox to v.42, the links don't work. In fact, when I click in the link, it doesn't do anything.

The problem is, I manage a web with some norms in Spain and this is a important problem for our users.

The document is http://www.codigotecnico.org/images/stories/pdf/seguridadIncendio/DccSI.pdf (Page.32)

Thanks in advance.

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.

Hello,

I really enjoy Firefox, but lately I've been having to go back to Chrome to get things done. The latest is that when I view a PDF in the browser the option to download the file does nothing. I then tried the same website on Google Chrome, the button worked and I was able to download the file.

I tried setting Firefox to open the PDF in Acrobat but there were no changes. I also tried using Firefox in Private mode in case an extension was causing a problem.

The website is the county records search site for Miami, Florida. Search for any name, view a record, the click on Document image. A PDF opens in the browser with a print option, and a download option. The download option does nothing when clicked on. Do the same on Google Chrome, then it does work.

Thanks for any help!

Firefox does not show up as an option for pdf files under Control Panel's "Choose default apps by file type".

The problem is on my wife's laptop, (a Dell Inspiron 5759). (Her Windows 10 is up-to-date.) She got a red screen phishing page on Firefox last week. (It claimed to be from Microsoft, and told her to call a certain number -- we did not call.) It essentially locked up her computer -- the mouse wouldn't move, even the power button didn't respond most of the time. I eventually had to unplug her power supply, and remove the battery. When it came back up from that, it responded; so, I uninstalled Firefox and deleted her cache folders.

I've reinstalled Firefox; but, now I can't associate pdf files with Firefox on her machine. Only Microsoft Edge is shown as available in "Choose default apps by file type".

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.

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.

Hi :) I have a problem with FireFox and I hope someone will be able to help me sort it out :) After the last update there is a new "feature" that is driving me insane and it's slowing me down to the point I'm ready to ditch FF. I'm talking about the "Open with Firefox" option, under "What should Firefox do with this file?". Is there any way for me to remove this "feature" from the dialog and to revert to the old "Open with..." and "Save File" list? Why is this thing there in the first place, I wonder?!

Thank you for you time and help!

When I used to click on a PDF file, it would automatically open in my default PDF viewer. Now it askes me to save even though I have set in preferences that PDF should be opened automatically with my PDF viewer.

Now I have to wait for it download, then click on it again. I do not want these files saved permanently, they should save to the %temp% directory and be automatically opened in the default program. Please tell me what I need to do to get this working again.

Thank you!

A number of months ago, using a previous FF version, I noticed that I could no longer open or download Adobe PDF files. No error, no blank screen, nothing - the only evidence of reaction to my mouse click is that the Adobe symbol on the page would disappear and turn into a circular progress bar (the usual reaction) but instead of anything coming up, the Adobe symbol would return. Nothing opened, nothing downloaded. I would check "Show all Downloads" and there would be none for the session. I spent an hour or two searching for advice (variations of this problem appear to be common) but nothing suggested there helped. Eventually I just gave up and reset FF back to its default settings. Everything worked fine after the reset, although I don't know how often I used it after that (but I'm pretty sure at least 5 or 10 times, successfully). Since then I know that I've had at least one, maybe more, FF install updates (automated, not by me). As of today I'm back where I started from - the same reaction when I click the link (momentary circular progress bar) but no view, no download, no blank page, no error message. I've repeated my 1+ hour help search online today (like before) to no avail. I assume I could reset to factory defaults but that is going to be a recurring waste of time, given how often FF updates, if that is the only solution. Surely there is SOMETHING I can change inside FF (or elsewhere) without always having to do a full reset (and lose any changes I've made). Here is my info regarding system and software and settings: Dell Laptop Windows 10 Firefox 43.0.3 Adobe Acrobat Reader DC Version 2015.009.20079 Up-to-Date Kaspersky license

As for my FF options and add-ons, I've tried every variation under the sun. In Options/Preferences/Applications I've set PDF Files to every available choice, including Save File, Preview in Firefox, Always Ask, Use Adobe Acrobat Reader DC (default) and Use Adobe Acrobat (in Firefox). Nothing worked. Under Add-Ons/Plug-Ins I have Adobe Acrobat 15.9.20069.28170 installed and I've set that to either "Always Activate" or "Ask to Activate," to no avail. Be aware that every time I've changed one of these settings and tried to download a PDF, the reaction was ALWAYS BEEN exactly as described in the opening description in this email - no variation in response to changes to any of the Add-On settings or the any of the settings for the Application Preferences for PDF files.

Any suggestion would be appreciated. For now I'll just have to go to IE.

I used to be able to read and print pdf files such as bills that are regularly sent to me on the internet. After last update Adobe can't can't read the files or print them directly from Firefox browser. I get a message to save file. I have to save the file to computer then use Adobe to read the saved file. How do I fix?

I know how to change the reader for PDF files to open with Adobe, but Firefox changes it back to the Firefox reader and I have to change it back to Adobe all the time. Why can't Firefox just KEEP my preference for Adobe????

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
