Hello,

I can't use the built in Highlighter anymore on locally saved PDFs. It only works on PDFs that are properly scanned in and where i can actually select the words. 2 days ago, I was still able to basically use the highlighter on all PDFs and draw on them however I liked. I haven't installed anything new or changed anything.

I also have tried to reset Firefox and reinstalled it. It's still not working.

I would really appreciate any help. I couldn't find anything based on my problems.

In the past, I was able to freehand highlight PDFs that did not recognize the Text. I was using this function this week; maybe the newest Firefox update is at fault. Without this, half of my documents are not really usable in Firefox. Everything else works. If it recognizes the text, I have no problems; the pencil tool also works just fine.

I read Firefox's suggestion to use the browser to edit pdf's and thought I'd give it a try, thinking I might be able to use it instead of my old Adobe Acrobat editor.

But I immediately noticed that there's no way to draw a shape with the Firefox pdf editor - a circle for example. The Help says I can select shapes from the Draw menu but the only thing that appears on my Draw menu is a line (see the attachment).

What am I doing wrong?

Since this morning, Firefox previews any PDF I click on, and then I have to manually download it for it to open in Acrobat. Acrobat is set as my system default. I have tried other suggestions found here, such as going into the troubleshooting and checking the folder profile, but nothing works. It is very frustrating.

idk, what i did, but i assume it's most likely user error. but i don't even know where to go from where i'm at.

ok, i'm going to attempt to identify what is happening. [guess] .pdf website previews are messing up the font when converting the .pdf to an image asset for the website to use as a current web asset, when the .pdf is updated. (makes sense really, smart drag & drop update of a .pdf menu, has instruction to make the end users browser do the work for you. kind of a one and done webpage coding for older guys that can't type, let alone edit Html, or even use Wix. some people just don't "compute" hard R or not. lol )

i don't even know where to start. i mean Mozilla is probably referencing it's own "lib.moz" which is just probably it's own personal link to an existing Lib file so it can pull it in and do what it needs to do with it without Root etc.

that is probably working fine as it renders (opens) the .pdf fine whence it's downloaded it. so all that i've talked about might not be the problem.

there is probably some mozilla function calling that to convert the .pdf as an image web asset so that it can show a preview of the current .pdf available for download.

that converter is messing up the font recognition, and building a preview image with messed up font characters (why it looks like Wing-Dings). but i don't even know where to start, and i don't think a new install will solve this (kinda overkill, and any residual files may still remain.)

i'm adding a fastfetch

Mozilla Firefox 152.0.1 " updates are manage by your operating system."

re-posted from; [[Why is Firefox PDF printing so strange?|https://support.mozilla.org/en-US/questions/1275786#answer-1276068]] and edited: reasons; support ticket gudelines [[Posting support requests|https://support.mozilla.org/en-US/kb/mozilla-support-rules-guidelines#w_subjects-covered-in-the-support-forum]]

[[i somewhat found an "answer" though i'd hardly call that "solved."|https://support.mozilla.org/en-US/questions/1275786#answer-1276068]]

i still say a Lib in a repo needs updated, within, or perhaps up stream of the project to reflect "commonly used fonts" if applicable (i know that's the trick, 'is it FOSS') yet other browsers use it, though idk if they're FOSS... i'd need to know what i'm looking for to confirm that or not, and do something about that (again most likely upstream, as the PDF Viewer is probably it's own project (or even several), retooled by Mozilla for Firefox.

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?

Once comments are added to a .pdf in Firefox, how can the comments be saved? The highlights show up in downloaded.pdf but when opened again in Firefox, the comments are gone. I want tosave the edited [with comments] document..how can I do that?

How to download a pdf without secure download ? I thought windows defender was the problem, but I can download a pdf without cleaning it with chrome.

My tax return declaration is made using a spreadsheet like pdf document, and when downloading it with firefox, the cleaned document cannot be filled in.

I clicked on a PDF website while searching for articles on relations between Ukrainian settlers and First Nations people. Instead of opening so I could read it, it was automatically downloaded as a file into Firefox. Unfortunately, I noticed the title had random parentheses in AFTER I clicked on it to read it. I updated Windows defender, and ran the offline scan. I also uploaded and ran MSN.com M.S.R.T. and Malware Bytes, but they found nothing.

What happened? Did I unwittingly install Russian malware into my computer, or does Fire Fox automatically download some PDF websites as files?

Thanks,

Charlotte

On loading some documents a popup appears asking me to "Sign on the dotted line". This shows a pencil making a signature. I am unable to move or delete this popup and therefore cannot read the document fully. I can't print it either as the popup obscures the printer instruction area. I would be very pleased to know how to remove/block/disable this uncalled for obstruction

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,

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/

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

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.
