Diễn đàn hỗ trợ Firefox

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.

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/

I'm having trouble downloading product specification PDFs in Firefox from Formers Paper, a thermal rolls manufacturer. Some files open correctly, while others fail to download or display properly.

Has anyone experienced similar issues when accessing documents from a thermal rolls manufacturer website? Are there any Firefox settings or troubleshooting steps I should check for PDF downloads and file handling?

Thanks for any guidance.

Hello,

I can't save and download a modified PDF file.

To put it simple: I open a PDF file on Firefox; Rotate it clockwise; Open the Tools menu (»); Click Save; The saving window opens; I save the file; When I open it, the file is as at start, before rotating.

Windows 11 25H2 26200.7623, Firefox 147.0 Thank you for helping.

I'm begining to regret installing v146.0!

One of the most useful features of Firefox is the PDF editor and with this update, I've found that after annotating a PDF with several text boxes, clicking the text box icon (as shown in the attached screenshot) does absolutely nothing and it is impossible to enter any further text. The only way out of this is to refresh the pdf (after saving otherwise all changes will be lost) and then starting all over again only for the error to repeat itself making the editor almost unusable. Would really appreciate knowing how to work around this especially since to make my notes clearer, I change the color and the font size which is all lost everytime I have to refresh the PDF :-(

Incidentally, why are there so many updates? I prefer stable software that works rather than 'new features' that I never use!

Finally, Firefox used to have an amazing facility of making the Firefox private browser the default browser for Windows 10 but this was removed some years ago and can only be reinstated by changing registry keys. Everytime there's an update, these registry keys are overwritten :-(. Why was such a useful feature removed please?

Thanks in advance.

Certain PDFs only allow page view when opened in Firefox. When opened with other PDF viewing software or browsers (Microsoft Edge, Adobe Acrobat, Google Chrome), these PDFs allow continuous scrolling. I don't have this issue for most PDFs.

I've tried fixing the problem by editing the PDF settings in Adobe Acrobat but to no avail. When combining a PDF that works fine with a PDF that doesn't allow continuous scrolling in Firefox, it seems to take on the settings of not allowing continuous scrolling.
