Very Weird Problem With Firefox

Hi Everyone.
I really hope that somebody can help, but like the title says, I have a very weird problem with Firefox.

I have an NFS share which I use as my Downloads folder sitting on my FreeNAS Server.

When I try to download from firefox to that folder I can get thousands of fragments along with the complete file. I attached a screen shot illustrating what I mean.

If I were to download the same file with Google-Chrome I don't have this problem.

I hope somebody has some idea why this is happening and how to get normal behaviour from Firefox.

Thanks

It works properly if I mount as cifs.
