Trying to not just edit a PDF in Firefox on Linux but actually edit the document using its Dynamic-XFA format elements of that PDF. XFA is an Adobe proprietary format that they depreciated several years ago but it still works in Adobe Acrobat Free. (I use a Windows guest VM for this as a workaround for now but I'd rather not since it takes extra resources and time). Elements can be filled in FF and some menu drop downs work in FF but other dynamic XFA element buttons don't respond like the one I attached.

In Acrobat the "X" and "Add Contact" buttons will add or remove some elements to the document.

Can this be done in FF desktop?

Version 151.0.1 (64 bit) on desktop PC.

In about:config I know there are a lot of options to modify under the search term "pdfjs" but I don't know what element would allow this to possibly work if its supported.

I wish I had other better options but government documents are what they are.

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.

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.

Download Issues My downloads have stopped displaying. Each page of a download is now just a black screen. Any advice as to how I can restore them?

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.

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.

All pdf files show all pages blank. It affects both those newly downloaded in Firefox and those I have stored on my PC and open with Firefox. I think this started from when the latest Firefox update was installed this week. I am up to date on Widows 11.

Starting a couple of weeks ago I haven't been able to open PDFs in my Firefox browser. Although there are other pdf viewers, Firefox has features that I use that the others don't. I've tried all the various ideas I've found elsewhere online but none worked. I submitted a ticket to our IT helpdesk, but they say it's a Mozilla Firefox issue. The error message isn't helpful at all, considering there is no web server involved.

I get the error below:

Access to the file was denied

Firefox can’t connect to the server at local file What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

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?
