    Hi,

    Anytime I download a file using Mozilla firefox it appears to download, but when I try and open it, the file is corrupt. If I download the same file using IE, Opera or Chrome it works fine, however I hate using those browsers as I am so used to Firefox

    I’ve tried a clean install and using a previous version, does anyone have any ideas?

    Using Win 7 Home Premium 64bit, system specs on left

    Thanks

    are you sure its not a harddrive or memory problem? i had faulty memory before and it would cause large files to become corrupt. It could be the harddrive and where its downloading the files to, try setting Firefoxes download directory to the same directory as IE or Opera and see if its the same

    Try starting a new profile for Firefox too, and try the latest 4 beta to see if that's any different.

    Good idea to test your memory, and if you're overclocking, try resetting to default speeds to see if that helps as well.

    Hi,

    I've tried downloading to a different hard drive, still the same! The same files download fine with Opera, so weird

    My memory isn't overclocked. Could it be firefox having a problem with my 16GB of RAM? Sounds unlikely i know, but i can download files fine with the same version of firefox on my media centre

    I'll leave memtest running overnight but i doubt it's faulty at stock.

    Keep the ideas coming, i love firefox and HATE opera!!

    EDIT - Just installed the new firefox Beta, same problem!

    you mean when you DL some stuff it leaves it in .part and when you try to run or delete it, it says it needs permission or something like that..


    well i have that lately, idk could be SP1 RTM fault, i just tried it now and it happened again,..

    So i re downloaded FF3.6.13 with Opera, reinstalled it, tried to DL with FF again and it stopped idk looks like its fixed.

    Never seen this but possible that firefox is corrupt therefore try all the steps here

    http://kb.mozillazine.org/Uninstalling_firefox

    btw do you mean corrupt downloads as in the file cannot be read when launched or do you mean its hanging at the end of the download

    Try it with a new fresh install of firefox without any addons at all (Remember to backup your bookmarks before fully unistalling)

    The download completes successfully, but when i open the zip or rar or try and run the .exe it tells me "the file is corrupt"

    I ran memtest overnight and got 6 clear passes on all 16GB of my RAM

    I'll try removing every single thing pointing to Mozilla later on

    thanks for your advice

    Try re-installing the driver for whatever network device you use.

    If you download the file with another browser is the file corrupt?

    Try Internet Explorer or Google Chrome for the test.

    Man, I had this a few months ago with Firefox 3.5. I tried a new profile, un-installing, re-installing and what not. Nothing would fix it.

    I even want as far as to completely reformat my computer. That still didn't fix the corrupt download with Firefox problem.

    It ended up being the fact that my RAM had just died. I know that your RAM is passing Memtest whereas mine was not, but I figured I would share my experience so you would know you aren't the only person that has encountered this before.

    I will be watching this thread and I hope we can all figure this out.

    I don't know if this will work but you could try disabling Firefox's built in virus scanner. It always gave me problems and would prevent my downloads from finishing. Sometimes it would crash Firefox altogether. Disabling it solved my problem.

    The problem must be to do with me having 16GB of RAM. Every other browser is fine, just Firefox with the problem

    Using *takes deep breath* IE9 at the moment

    I just can't get used to Chrome or Opera!

    I have the EXACT problem as yourself, only not with firefox but with ANY other browser.

    Supposing I am downloading some porn from rapidshare, if I was to use firefox it would download 100% no problem...

    However, If I was to use opera or internet explorer, the download may reach 10% or 20% and then it randomly stops, so it's incomplete and does not work...

    Still unsure why it does this...

    Files download perfectly fine with ANY other browser

    So strange, but extremely annoying

    I might take my RAM sticks out one at a time and see what happens.......

    Same here

    Same here, and for a long time. In fact since version 3.6, in all version, up to version 15, across 2 different computer, an old one with XP and my brand new one with 7. I now use Waterfox 64bit version 15, and it's the same problem.

    The problem I have is the file size that is smaller than it should be. So obviously, the archive (zip, rar, 7z.) is corrupted. I managed to drill down what trigger the error and found a partial solution around thew problem (never really solved it).

    I rarely download to the default folder. Instead, I browse to the folder where I want the file to go to. That takes time and the thing is, as soon as you click a download link, the download actually start in the background to the temporary folder. This is where the problem happen. If I fool around too long (say over 10 seconds) to get to the destination folder, the file is always corrupted.

    I also found that the smaller the file, the less time I have to select my destination folder. It seems the bug is proportional to the size of the file you download. At some point no matter how large your file, if you wait too long, it' will get corrupted. Note that oddly enough, is the file is very small, say below 300-400K, it's never corrupted.

    I have found that if I select my folder and click "save" withing 5 second, the vast majority of my files are NOT corrupted. So the whole problem is how Firefox manage the buffered download until you press "save".

    My PC is 100% stable (prime95, Intel burn test, 3dMark, all pass 24H loop). Every BIOS, firmware and driver up to date. No crash or odd behavior whatsoever on my network, with my NAS, HTPC or other network devices. I tested with fresh install of Windows 7 SP1 and fresh install of both Firefox and Waterfox. Download are always 100% OK with IE or Chrome, no matter if I leave the file requester open for hours before I press "save". (actually tested it)

    This is clearly a Firefox issue, has been for a long time, and it's reported elsewhere on the web.

    ^Holy thread necro batman....:3eyes:


    It's probably your memory, Mozilla is very sensitive to unstable/faulty ram for some reason.
    I've used FireFox and now Waterfox...never had a problem, can't say I've heard of many others with your issue either....
