I-Firefox Community Forum

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.

So PDF's can no longer be set to open in Adobe, but it now requires clicking before the document opens in Adobe. No setting whatsoever can change this. Is this a permanent setting? Will have to move to another browser now. What a hassle. Got to move bookmarks, set up home pages etc. Ugh. Bey Firefox....

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?

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.

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.

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.

Hi,

I added some annotations to a PDF using Okular on CachyOS. When I open the PDF in Chromium’s built-in PDF viewer, the annotations appear in the correct positions, just as they do in Okular. I also checked using a few online PDF viewers, and the annotations display correctly there too.

However, when I open the PDF in Firefox, all the annotations appear in different positions than they do in Okular.

When I set Firefox as my default pdf viewer and click in Macos Finder to open multiple files nothing happens. Clicking on one file it opens it fine. Used the "Troubleshoot menu" to disable extensions and disable custom settings, same behavior. At one point I disabled "hardware acceleration" and it actually worked. Then it stopped working, not sure why. Any ideas?

Thank you.

Your browser needs immediate attention! I have windows 11. When I visit websites via Firefox and click on a link that takes me to a document, a large pop-up on the lower right side of the screen appears blocking half the page and preventing me from downloading or printing it. The pop-up depicts a cartoon-letter with a highlighter pen traversing its cartoon-text, below which is an enthusiastic missive stating (and I quote): "Now you can highlight your PDFs! With our new highlighter tool, you can read and edit PDFs in one place." Because of this infernal nuisance, I cannot print or download web pages. This has been going on for WEEKS! (That pop-up is USEFUL?! Who thinx up this stuff??!!) Apparently you're having trouble fixing this problem ... I understand--I'll just use Edge or Chrome from now on. Sorry if I woke you.

When filling in the PDF documents, at each section/line I move too, the font reverts back to the super large size, without being prompted too. Is there a way to set the font, so it remains the same, unless prompted? When attempting to adjust the font, it goes from super large to super small, any suggestions to set the font in between these two sizes?

• • I opened up the document from my email and began working from there. Should I use a PDF program and not from the email?**

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 closed a PDF file but can not move it to another folder. Windows says it is open in firefox. I closed firefox and it still says it is open in firefox. I even restarted windows and it still says it is open in firefox. How do I get firefox to close and release the file?

I have looked at some of the comments about Firefox automatically opening pdf docs. Myu concern is twofold. Most importantly the password in the doc is somehow being overriden; that is a severe security issuen for me. Destroys the whole concept of security. Makes me very uncomfortable and may discontnue using Forefox after more than 15 years. Secondly this caught me by surprise; it only occurred for the first time this morning. How can i overcome this to prevent Firefox from performing merely as a browser?
