but with other browser (like Internet Explorer , Opera , Chrome) when i try these tar (tar.gz) , the archive file rightly could be downloaded.
P.S : this problem not happened with all tar (tar.gz) files and firefox , with some of them happened . ( i mean , with other sources, except the link  bellow, in some other web pages , when with firefox tried to download tar files , same problem happened

Does the issue still occur if you start Firefox in Safe Mode?

How about with a new, empty profile?

WFM with latest nightly

I am able to open the file you attached using 7-zip with all versions of Firefox I tested. 

How do you know these files are corrupt? What zip program are you running? You may want to try 7-zip from

Well , i tried with winrar .
Now , i try with 7zip , confirm u (i mean after downloading with firefox , 7zip could extract it , guess 7zip automatically make repair when user extract ...)

Anyway still the problem is concern about firefox (not winrar problem) because when with other browser like chrome , IE , i download the same link , even with winrar could extract it well here . but when use firefox + winrar -> error log shows the file is corrupted.
would u please try once with winrar ( i am sure , u could reporduce the problem with firefox and winrar .

Thanks in advance
