I-Firefox Community Forum

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.

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 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?

I use a notetaking app called xournal++, which is helpful with graphic tablets.

There is this issue that seems persistent, When I annotate anything via xournal++, I export it to pdf and view it on firefox, The highlighting which is supposed to be slightly transparent, Appears completely opaque, blocking text underneath it

Now I Would normally contact the xournal team, but it seems this issue is only present in mozilla's pdf reader

I have tried opening other pdfs, although the same results occur

(Also apologies in advance I have no clue which category this should be in)

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?

Trying to not just edit a PDF in Firefox on Linux but actually edit the document using its Dynamic-XFA format elements of that PDF. XFA is an Adobe proprietary format that they depreciated several years ago but it still works in Adobe Acrobat Free. (I use a Windows guest VM for this as a workaround for now but I'd rather not since it takes extra resources and time). Elements can be filled in FF and some menu drop downs work in FF but other dynamic XFA element buttons don't respond like the one I attached.

In Acrobat the "X" and "Add Contact" buttons will add or remove some elements to the document.

Can this be done in FF desktop?

Version 151.0.1 (64 bit) on desktop PC.

In about:config I know there are a lot of options to modify under the search term "pdfjs" but I don't know what element would allow this to possibly work if its supported.

I wish I had other better options but government documents are what they are.

The original post is one of the top search engine results, and provides a bandaid solution, without addressing the proper root cause, so I want to help whoever stumbles over this.

Original problem:

Dale 1/9/21, 8:26 AM

Firefox Developer Edition 85.0b4, macOS 10.15

If I Google for a PDF and click a link, I get the Firefox download dialog. If I select "Open with Firefox [Developer Edition]", the following things happen:

   The PDF is downloaded to ~/Downloads
   The PDF is opened in a new tab, with that new tab's location bar holding a file:///... URL to the downloaded PDF 

What I would instead like to happen is:

   The PDF is downloaded to some temporary directory where I won't have to worry about deleting it manually
   In whatever tab the PDF is displayed in, the location bar contains the URL where the PDF was (temporarily!) downloaded from 

How can I achieve this?

Not having the URL where a PDF was opened from is very annoying when, for example, I open a bunch of PDF search results to read and review, and I later want to share links to some of those PDFs. Best I can do to find their URLs to give to others is then to try and remember which tab corresponds to which search result, or do mine the downloads tab.

Contrast this with Chrome: I click a Google result for a PDF and the PDF just opens in the current tab with the URL to the PDF in the location bar. No dialogs, no PDF files hanging around in my home directory, and I can just copy the URL to the PDF the same way I'd copy the URL to any web page.

Thank you!

Sigh. It appears the problem was one or both of the following preferences:

   pdfjs.enabledCache.state: false
   pdfjs.migrationVersion: 2 

I deleted both, and now clicking on a PDF just opens in the sane, normal way in Firefox that I desire.

Naturally I have no idea how those got set.

I just went to The IRS and filled out a pdf form to change my address and the print or font was in blue text I Want it it to always be in Black font text please let me know how to do it. I have font contrast and blacken as extensions. Do I need to do t in my windows 10 computer

Editing a PDF is a great feature. Entering a text in Hebrew results in a PDF that, in some viewers (like your own) , the text disappears. When opening the file saved in Adobe Acrobat, it's fine.

All pdf files show all pages blank. It affects both those newly downloaded in Firefox and those I have stored on my PC and open with Firefox. I think this started from when the latest Firefox update was installed this week. I am up to date on Widows 11.

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.

I was having an issue with pdfs on firefox; all my pdfs were showing up as black. To fix that, I refreshed firefox, which solved the problem just fine. Unfortunately, once I did all my extensions stopped working. The page looks like this.

For most of my extensions, I can just solve this by getting rid of them and adding them again, but if I do that for onetab I'd lose all my stored tabs. How can I get this back?

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 opened a new window and dragged a PDF into it. While the icons in the upper right do not include Edit, I just went to the field I needed to change (an alarm permit renewal, change of email). A box opened "somewhat" over where I clicked, and I was able to enter the new email, but I could not delete the old one. After saving and opening in Acrobat, both emails are written over each other, making both unreadable.

I cannot highlight my old email in the original form in order to select Delete. When I type my new one, a trash can appears, but that is for deleting what I just entered.

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?
