Select Privacy & Security in the left panel.

In the settings window, use the dropdown menu next to the https://www.adobe.com to change permissions, and then select Save Changes.

Find Local network access under Permissions, and select Settings.

Use the dropdown menu next to https://www.adobe.com to change permissions, and then select Save Changes.

As of today, every single time I try to download something, Firefox instantly cancels it and I'm not sure what the issue is. I've disabled adblock and Malwarebytes and refresh Firefox—same issue. Hitting retry from the download panel works but I can't figure out why the first download attempt is always cancelling, even if it's the same file. I'm not even downloading big files.

I've file download feature in my web application. When polling of file percentages is complete i am sending file to the client (browser) But in fire fox it downloading an .html file instead of actual file. Whereas in chrome it working as expected.

I had recently tried to download a .Zip file, which got corrupted. I tried twice again. Now every time I open the browser the three corrupted files pop up in the "downloads" window. It does not appear when opening a new tab, only when starting the browser. I have deleted the corrupted folders and don't want to retry downloading. I have tried both "clear all downloads" and "remove from history" in the downloads window, but the notification still shows up. Settings do not help.

How can I remove this pop-up? It blocks my toolbar and is a general nuisance.

I'm unable to download any of my Intel updates. I've turned everything off that I know could be blocking it and authorized Intel as a safe download. I don't know what else I can do please help. Google states that I should be able to go to the shield and the address bar and turn off the enhanced tracking protection however it will not allow. I've gone to the settings page and set it to custom as well as clear all check marks in that setting. Still nothing will not allow me to download my updates for my Intel drivers. Please help

simply that except for the odd ocassion, I cannot download documetns generated by Copilot when i'm using firefox. I uninstalled Firefox and it worked on Edge but for a while and then i started having problems with that as well. For several months when i first started usin Copilot, it worked fine and then suddenly I started having problems.

I am unable to download large files from an MS Sharepoint account in Firefox. Small files are fine (less than 100MB). Large files download fine if I use MS Edge browser but I don't want to have to use Edge unless absolutely necessary. Using Firefox Troubleshoot mode doesn't help. Clearing the cach/cookies etc doesn't help. When downloading a 600MB file, the download repeatably fails around 90-100MB. My OS is Linux Mint xfce64. Obviously MS doesn't like firefox for some reason, even in Troubleshoot mode. thanks in advance for any help.

All of a sudden I can't download files from apps I use all the time... and download files from all the time. I just tried in Edge & I can download just fine. This just happened this morning. I downloaded multiple files yesterday within firefox & the same apps I'm running today.

I'm running Linux devuan: Linux MikesPI 6.1.93 #1 SMP PREEMPT Mon Dec 8 02:37:53 CET 2025 aarch64 GNU/Linux and Firefox 140.4.0esr (aarch64).

For years now I've been downloading and saving Yahoo quotes as csv, now for the last week Firefox wants to save page image poping up an extra window that must be refused before I can continue using Firefox. Hopefully someone can tell me what new option in about:config can be turned off to stop this. Thanks, Mike

Hi-

In the past week or so, I suddenly stopped being able to download/save files or upload files from Firefox. I get a message that says something like "You don't have permission to open this file". This happens regardless of the location of the file (ie locally on the device, a USB drive, a server drive, one drive etc.).

This happens on two different workstations, one is Windows 11 and one is Windows 10 but both use the same Windows login.

If I try a different browser, I am able to save or upload so I don't think it is a network permissions issue.
