Hello, I have Firefox for Android 151.0.4 on a Samsung A50 with Android 9. On the SD card of the device I have several pdf files which can be opened with Adobe Acrobat with no problems. Instead, when I go to the device's file manager, move to that SD card, long-tap on one of those pdf files, tap on the three dots to see more options, choose "Open with" and finally select Firefox, I have that Firefox opens with a "File not found" page and the address bar shows, for instance "content://media/external/file/22098" while the pdf file I tried opening is "/SD Card/Test.pdf".

Is it possible to open local pdf files on my device with Firefox for Android? In the positive case, how can I do it in my case?

Thank you

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.

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.

I go to various websites, in this case https://go.valcom.com/EZ-GW1Rezipinstallationmanual (as well as other pages on this same site) and when I try to look at a manual or specs in pdf format, I get a blank screen and the URL looks like the go. and everything after the .com are grayed out. These work fine in Edge and Chrome. This also happens in Troubleshoot mode. No hardware or software changes on my desktop.

I have my settings set to open PDF files in Adobe Acrobat, but the latest version of Firefox has started opening them in their own viewer, which is NOT near as useful, and I then have to download it to open in Acrobat like I used to do. Why? Is there any way to fix it back?

Pressing print/pdf button for screenshot then pick the folder destination documents then press save and what it's used for is decrease the size of the screenshot with pinching the screen then retake the screenshot of desired smaller size however for the first time it has an error in documents folder the says "can't open pdf" and then I tried the 3 dot menu in upper right corner to use an app to open it up and I went through all of them and nothing works

I am currently revising for professional qualifications and the PDF study manual I am using is extremely large.

I have seen tutors be able to use the document outline on the left sidebar to be able to filter through different chapters.

However, I do not have that option - I only have the option to view page-by-page which is not very helpful.

How can I get the document outline to show a chapter-by-chapter outline?

Hi,

I'm wondering if fonts installed locally on Windows/PC can be supported in Firefox PDF Editor any time in the future? If you add this feature, it can bring huge productivity boost to us, the Firefox users. Just wondering if there is any development (or even a consideration) on this.

Best,

Anytime that I open a pdf using firefox the page will load but will just leave a blank page with nothing displayed. Reloading does not help and I have tried to change my settings around to no avail

Hi Mozilla Support Community,

I use Firefox Desktop as my primary browser for running a corporate consultancy agency. Recently, I've noticed an issue with Firefox's built-in PDF reader (pdf.js) on certain official interactive forms.

When downloading, previewing, and filling out business registration forms, MOA templates, or tax certificates from corporate web portals (such as the SECP Portal Pakistan for company name search and FBR verification tools), certain custom font fields in the PDF appear overlapped or fail to display input text properly.

System Details:

Firefox Version: Latest Desktop Release (Windows 11) Issue: Form text fields in interactive PDFs fail to render non-standard font glyphs properly. I wanted to ask:

Is there a specific preference in about:config to force Firefox's PDF.js viewer to fallback to system fonts for interactive form fields? Is there a way to reset pdf.js rendering cache without clearing general site cookies and sessions for web applications? Any troubleshooting tips or about:config tweaks would be greatly appreciated. Thanks! https://secpportal.com.pk/

When viewing a PDF in Firefox the URL bar indicates the file was downloaded to a temporary folder. If I then select "Save" from the PDF toolbar; or if I right click and select "Save page as" it opens a save dialog to the location I previously saved the same category of PDF to. For example I have separate folders for invoices, if the PDF is my electricity invoice it somehow knows and opens the electricity folder. If it is a water invoice, it automatically opens the water folder.

Whilst this is indeed quite handy, I do not understand how Firefox is doing this; nor do I understand whether this may be a privacy risk in some circumstances and should therefore be configurable.
