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.

Trying to download Firefox.com. Screen states “ your download was interrupted “ No explanation why or what to do to allow download to succeed?

Using the Firefox 151.0 Mozilla Firefox for Fedora. Updated as of 23 May 2026, I use just a generic FireFox. I don't customize it, I just use it as it comes from the Fedora distribution.

I cannot save images (right click menu "Save Image As"). Nothing happens when that is selected. This worked a couple weeks ago.

Downloads are supposed to go to ~/Downloads. Checking the setting for this, Go to the three-line menu > Settings > General > Files and Applications, under Downloads, the "Save files to" value is set to Downloads, but the Browse button does not work to reset it. Nothing happens when I poke on the button. I can select the text in the box, but I can't change it.

I found the help page for "What to do if you can't download or save files https://support.mozilla.org/en-US/kb/cant-download-or-save-files and went thru every one of the steps there. None of them make any difference.

Strangely enough, there isn't even a "Downloads button" in the top toolbar. If I right click on the top toolbar and select "Customize Toolbar" it shows a downloads icon as already being in the toolbar, but when I click Done, it goes away.

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.

In some regions, the offline translation language packs fail to download properly in Firefox. Users are unable to complete the download, which prevents the translation feature from working offline. Please look into potential regional network restrictions or server accessibility issues. Thank you.

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

Hello. I have a question regarding a problem with exporting files in Firefox. For about four days now, when I try to export files in Firefox, it fails. I've looked into it, but haven't been able to find a solution. Could you please give me some advice? I've tried various things within my capabilities, but nothing has worked. Firefox 150.0.1 64bit

Mac Tahoe 26.4. Any attempt to download or upload results in a file chooser/picker/browser panel that shows part of the finder interface but not all. Can't interact with it besides switching between sidebar items, no files visible, can't close or exit this window, can't interact with anything else. The only active button on the top of the window is the fullscreen button. Have to force quit firefox every time.

I tried troubleshoot mode and it did nothing. There is a workaround for some download links where I can open them in another tab and they automatically download without opening the window. Drag and drop options seem to work for uploads when they're available.

I took screenshots and was going to attach them, but this problem prevents me from doing that. This browser's sorta bricked for me at the moment.

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.

Hello all.

For a while, all downloads have failed on Firefox (150.0.1), Windows 11. No file downloaded, and download tab shows a 'failed' underneath the file name. This holds true when downloading any file type, via firefox directly, or an outside app (Discord, for example) that hooks into the browser. Downloads work on other browsers (Chrome).

• I have checked about:config and reset the recommended options from other articles ("...lastDir" was the only one of the list that had an entry).
• Starting in Troubleshooting / Safe Mode does not fix.
• I currently run Norton - disabling it did not seem to fix.
• I don't have a Family group, so it's probably not the parental controls issue (though I think that was solved?)

I recognize that the lack of ability to download in Safe Mode points towards the possibility of an outside program blocking downloads, but I'm at a bit of a loss, since other browsers do work.

Thanks in advance for any ideas or suggestions.
