I'd been trying to download 2 large files from Icann and kept getting premature completion with Firefox. It would be showing ##MB of 356MB downloaded for a few seconds and then out of the blues it just says completed. As you can see in the shared video, I've tried this several times.

I thought that maybe one of the Firefox addons was causing the issue so I tried Troubleshoot Mode but that resulted in the same behavior.

I then went into Firefox Profile Manager and created a new profile. But that too had the same behavior - 🤔!

So I then tried Chromium. It completed the download successfully and the file passed gunzip test.

So, why is Firefox, even with a new profile, failing to complete a download?

I have recently encountered reproducible failures when attempting to download files or save pages to local storage. The target directory is located on a mounted NTFS file system with the options umask=007, user=root, and group=disk. My Firefox browser is running under a non-root user account that is a member of the disk group. However, I consistently receive the error message: “XXX could not be saved because the source file could not be read.”

I would greatly appreciate anyone's assistance in resolving this issue.

I upgraded to Firefox 135.0 the other day and tried it out on a site I have used several times a week for at least 10 years. A .csv file that I regularly download failed to do so. The system simply failed to respond, and nothing appeared in the download window. The site offers the option of downloading the same data in a .xls file, and that worked. (My previous, obsolete, Firefox gave me the option of where to download to, and remembered the choice between vists. Such is progress!)

I received this download from Firefox today, July 22, 2025: xRqj7qhl.html - Size: zero bytes - Kind: HTML text . I've never experienced this before. Is it legitimate? Thanks

I access google drive through Mozilla Firefox and also zip file or other file download but since 1 to 2 weeks i faced issue to download files especially js file.How can I solve this?

Hi! I've recently found an issue with VirtualBox Extension Pack download in Firefox. Instead of downloading the file, it just shows me a web page with a lot of gibberish, like its trying to display the content of the file itself. I'm using Windows 11 and no extensions in Firefox. The only way i have for the moment to download that file is through Edge. Can you tell me why this happens? Here's the link: https://download.virtualbox.org/virtualbox/7.1.12/Oracle_VirtualBox_Extension_Pack-7.1.12.vbox-extpack Thank you and best regards.

I have been trying to save images from a game I play to file (locally). I've been doing this for years, but now all of a sudden within the last (week??) it's not doing it AT all.

For one thing it now opens my in-game image - into a whole new tab (which is absolutely bizarre and annoying!!)

When I DO go to 'right click' on this image to save, I have it PRE-SET to go to my preferred location to save as a PNG file.

I go to windows explorer and it's NOT there. I try it again! Saving it as a JPG, NOT THERE.

Restarted the browser... tried again (resumed the game, got to the place where I wanted the screenshot..it's an ingame 'screen shooter' that's worked for me for years in Opera and Chrome).

It GRABS the screenshot, no problem! But to save the image (no matter the file format) it WILL NOT DO ITTttttttttttttttt

I am going bonkers. I have double checked the file path. I've given it a VERY Specific name JUST in case if I DID save it somewhere 'stupid' lol!! I've checked my 'screenshots' folder! (Which is also bizarre to me!) These images *Are noooooooooowhere*

This is a very new thing for this browser (For me!)

i've gone through my Firefox settings insofar as I can see - with a fine tooth comb. I've cleared ALL CACHE and TMP folders, REBOOTED the system, restarted my browser (which is supposedly fully up-to-date! I Check on this *Daily*)

Can you please help me out here?? this is driving me bat sh*t crazy I'm the desktop PC/Windows 11. i've run scans for drivers! For any system updates! My browsers are ALL up to date!

I tried running this in Opera and it works!! But I need to keep things separate and chose Firefox for this particular game (in-browser).

I am at a loss and can't think of what else I can try to do! (if there's a setting I've over looked! if this is a known issue... I have lost the patience to try and filter through the help pages I'm so sorry) this has put me to my wits end.

Please help. Thank you so much.

I tried downloading an APK from memesAPK] but Firefox didn’t save it properly it just showed up weird instead of a normal APK file. Has anyone else run into this or know how to fix it?

Trying to download a zip file to be able to move forward with this job offer with Turbo tax and it will not let me. Need to find & remove the problem they said. I have no tech experience. Please help.

Hello, I am having problems downloading a torrents. When I hit magnet nothing happens, looks like its being blocked for some reason. I disabled Defender but that didn't help..

 Any help would be greatly appreciated .

obviously you think everyone is a programmer by the was your system does not work doing updates !!

I am hoping your not expecting an 80 year old lady to fix your lack of diligence? or should i just eliminate your program?

My downloads keep failing every time. I tried everything from this list but all I get is download failed, this has been an issue for years. I have to press the try again button about 3000 times for it to slowly download a bit by bit but for larger files its impossible.
