Describe the bug

If I want to upload .exe files in firefox, it looks weird: there`s a progress bar on file uploading status and it goes like 10%-100%-20%-100%-30%-10%-40%... and keeps coming until timeout reach. This only occurs in firefox browser, tried different version (1.7.0,1.8.1,1.9.1), if i try to upload different extension (.jpg,.html etc) it works fine.

I've make some research on this problem, and there`s something with "Upload?token" response: it keeps making responses until it reaches 200 status.

@Ank2503 This was a dupe of #4704 and should be fixed now on tip-of-tree!
