I-Firefox Community Forum

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?

I've searched the community for support to add bookmarks inside my PDF files using Firefox, but all I get are articles and community posts from two or three years ago.

I currently see no features or buttons to edit the outline of a PDF using Firefox (153.0.4). Are there any Firefox extensions or other Firefox methods that I can use to do this in the meanwhile, or do I have to resort to using third-party software and solutions?

Where can I suggest to add this feature if it doesn't exist?

Thank you for reading.

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)

When I select text in firefox's built in pdf viewer, a menu with comment and highlight options automatically pops up. I haven't been able to figure out any way to turn this off. This is a problem because when I'm using the viewer at work firefox now puts this menu exactly over the next piece of information I need. (eg blocks the next row in a process log)

I am using Firefox 153.0.4 (64-bit). Windows 11.

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.

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 have Firefox set to always ask about how I want to open/save PDF files. Within the past couple weeks, I've encountered an issue with opening PDF files. When I click on a PDF and select "open with Firefox," the PDF opens in a new tab on Firefox, but it also opens in Acrobat. When I select this option, I just want the PDF to open in my browser, and I cannot find a way to stop it from simultaneously opening in Acrobat.

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 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
