Firefox Community Forum

Since the update to Firefox a few days ago, I am no longer able to view PDFs in the browser. They still open, but they show up as blank pages. Is there a way to fix this or to revert back to the previous version of FF?

Thanks.

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.

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?

I'm filling out an appcation for a study permit in canada. My university website said that i should download adobe acrobat reader and use it to open the application pdf. I didn't want to pay for adobe, so i opened it with firefox instead. In the document, there are tab selections that it allows so you can select answers accurate to you and fill out the document. But at the top of the document it says I should enable javascript by going to preferences, then edit, and and then reopen the form. How can I enable javascript in firefox? I'm having difficulty finding the preferences and edit sections.

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 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.

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?

Why has Mozilla decided to COMPLETELY IGNORE security settings applied to PDF documents? I have a number of PDFs secured so as to prevent the ability to print or copy text. When opened with Firefox, all of these settings are ignored.

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

Well, there is a bug with your downloading files configurations that REALLY ANNOYS me, which is, i want to always select where to save my downloaded files, no problem with that, i just set all configurations to "always ask", but sometimes, especially for pdfs, i want to just open them, without the need to save them to my computer, so the only one i have set as "open with firefox" is the pdfs, and if i want to download them, i just do so by clicking the download button on the corner. BUT, with this configuration, if there is a button to download a pdf, without opening it previously, it will skip the "ask where to download" pop-up, which is a pain in the ass, as usually want my stuff in specific folders, not the general downloads one. And even iff i set pdfs to "always ask" and then chose to open with firefox, it will automatically download it (???????) to the downloads folder, and then open it from my pc, even tho it could open it from the file in the server, which is what i wanted. I just switched to firefox, please fix this awful feature and dont make me find another browser.

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.

When I try to select some object on a pdf page, a little window appears with "select" and "comment", and the window blocks other objects of the page. How to remove that forever? That is very inconvenient.
