When I try to download my credit card year end summary on my MacBook Air I get this message, "Your browser is unsupported and unable to display PDFs" I have done this for years and never had any trouble. I checked for Firefox updates for IOS and it says Firefox is up to date. It also says I am on the esr update channel. Why would this suddenly be a problem? How can I fix it? Thank you for any help or insight you can give me. PS I am old and no longer tech savvey. Technology has left me in the dust! So please be as untechnical as possible in a response if I am so lucky as to receive a response.

I am an academic. I use Canvas. When I am in Canvas and I try to open a document in it from Firefox, what I get are solid black pages. I do not have this problem with Canvas in Chrome or in Edge. I really don't want to use those Browsers. I actually have this problem with every PDF I try to open from all sites. This is a recent problem. But if I cannot correct it, I will have to use other Browsers.

The past two days Firefox has not been displaying PDFs properly, turning 2 out of 14 pages sideways. I restarted my computer but no change. The PDFs display beautifully in Edge.

When I try to download a statement from my bank I just get a blank page pop up. This used to work with Firefox and it works OK with Chrome. What has changed ...or is there a Firefox setting that is wrong?

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

I often use Firefox to read PDF, but whenever I add highlight to it doesn't save it to the same file but rather as to save a copy of file which is very annoying I end up with two version of same file I am reading and it because very irritating, how do I make it to update the file which was open rather than saving a new copy.

Up until a few days ago I was able to preview yahoo mail attachments (e.g. PDFs) before downloading them. I don't know what may have changed, but I don't recall doing anything on my end. Any suggestions or advice on what settings I should consider changing greatly appreciated. M

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?

I just had a Firefox update and it stated: Edit PDFs in Firefox. How do I find this feature? I've looked in settings and all things listed from the "hamburger" menu and can't find it.

Hi everyone,

I’m running into a frustrating issue where Firefox is opening PDFs in two places at once.

The Problem: When I click a PDF link, Firefox opens the file in a new tab (internal viewer) but also launches the standalone Adobe Acrobat app to display the same file. I only want it to open in Firefox.

Details: - Settings: My "Applications" setting for PDF is currently set to "Always Ask." - The Glitch: Even when I manually select "Open in Firefox" from the prompt, Adobe Acrobat launches anyway. - Timeline: This started happening 2 days ago without any manual setting changes (I think it might be after a firefox update? I might be mistaken)

- Troubleshooting done: I have tried toggling the action to "Open in Firefox" directly, but the dual-launch behavior persists.

Thanks

I create and save files in OneDrive. When I open a file, it always opens in the Microsoft Edge Browser which is a problem for the old guy, me. I prefer that they open only in the documents folder as their specific kind of document; Word, PDF, and Excel spreadsheet files so that I can then move my files into various folders and sub-files. Hopefully, someone can figure out what I have said and help me. • I'm uncertain if the topic I chose accurately describes my question.
