Forum communautaire Firefox

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.

When I click on a PDF link it will auto download the PDF but then if I click on the same link again it opens it inline. I want it to always open inline and if I wish to save it I'll manually do that.

I've looked around and I found this that mentions using browser.download.start_downloads_in_tmp_dir and browser.download.open_pdf_attachments_inline. While setting the downloads to be in the tmp dir is nice for not clogging up my downloads it still doesn't solve the issue of opening and not saivng. The setting for opening pdf attachments inline sounds like it should fix it but still every time the first time I click it, it starts downloading it.

Is there any other setting that could stop this or some reason why those settings might not apply in all situations?

I use Firefox as my default program for opening PDFs. But if I try to open more than one at the same time it will always leave one out and instead open a "New Tab" that I don't need. Can't figure out why or how to fix it.

Example: If I check (windows 11) files A, B, C, D, and E. It will open A, B, D, & E and a "New Tab" and leave out C.

Any Solutions?

Hi, Firefox is hard to use for me right now. The screen turns sometimes black while using the browser. Especially when opening pdf documents in Firefox the screen turns black before the document opens. Also, after switching to another tab or App the pdf is not visible anymore and also black (see sreenshot). I have tried reinstalling Firefox and also start in troubleshoot mode. What is the issue??

Thanks.

Sebastian

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)

Hello I just filled out a pdf and the font or writing came out blue I want it in black is there some where in Firefox i can get it in black w font or writing please Advise thank you

I recently noticed that EVERY pdf I open for reading is being saved in my computer's Downloads folder! DESPITE my Settings "Ask where to save files before downloading" and "Ask to open or save files." I am enrolled in an online certification program: There is LOTS of reading. LOTS of information being shared through the class portal. I just discovered this mess a couple of weeks ago.

Today, I added a check mark to Other Files under Settings: "Delete private window downloads on close." I'm hoping this will resolve the problem. Am I missing something??? WHY is my longtime browser doing me like this?

FYI: I'm using the Windows 11 OS on my six-year-old laptop. My Firefox (152.0.5) stays current.
