Ok it seems that this is still an issue in Firefox 25.0.1 (on OS X).
I am using https://github.com/PixelsCommander/OnlineJS which sends XMLHTTPRequests to a server to check if the server is online. Sometimes the return status is 0. About 5 of 100 request the status is 0.

Other browsers are working without any problems.
Maybe someone can confirm this issue.
