Firefox Community Forum

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 often open PDF links in Firefox. I can choose to open the PDF in a Firefox tab. If I leave the tab open and restart my computer, or look for that tab sometime in the future, I often see a page that says File not found (see picture). Somehow the page is being cleared out of the cache. Not sure if Firefox is doing this, Windows or some other program. Any ideas to keep these pages so I can see them in the future?

Trying to read PDF pages in Firefox. When I click on a file it says "You do not have OpenText Content Server Browser Web Extension 2.0.10 installed, or it is not enabled. Follow these instructions to install and enable the extension." I've looked in the extension add ons but cannot find the appropriate add-on and when I go to download from file, there are no files that would are appropriate either. Any suggestions? Also, I'm using a federal government laptop if that has anything to do with it.

Thanks guys for any help you can offer....

I have Firefox set to always ask about how I want to open/save PDF files. Within the past couple weeks, I've encountered an issue with opening PDF files. When I click on a PDF and select "open with Firefox," the PDF opens in a new tab on Firefox, but it also opens in Acrobat. When I select this option, I just want the PDF to open in my browser, and I cannot find a way to stop it from simultaneously opening in Acrobat.

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.

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.

Mozilla/Firefox is my browser. Lately, every time I am on a website where I need to open a pdf document, like a bank statement I want to download, a pop-up appears that advises me to sign on the dotted line or anywhere and shows a little pen writing something. Underneath is this sentence: "Draw, type or upload your signature, then place it exactly where you want. Save your go-to signature for next time."

Where did that come from? It blocks my view of the document and if i try to capture it in a "screenshot" nothing appears. Is this a Mozilla/Firefox thing or a (Acrobat) pdf thing? And what can I do to stop it?

Hello Mozilla Support Team,

I have been using Firefox for a long time, and recently I upgraded my Windows system. Before the upgrade, I had set Firefox to open PDFs directly in a PDF Reader other than Firefox’s built-in PDF viewer, and it worked perfectly. However, after the upgrade, Firefox now shows the "Opening when completed" message and opens PDFs slowly, instead of opening them immediately in my chosen PDF Reader.

I have checked the settings, cleared the cache, refreshed Firefox, and even tested with other software, but the issue persists. The settings for handling PDFs are still the same, but they don't seem to work as they used to.

Can you please assist me in resolving this issue? Any help would be much appreciated.

Thank you
