Firefox browser occasionally downloads unknown htm files with 0KB size. If I open the file, what I see is just an empty file opened in firefox browser. I have absolutely no idea why this is happening or in what situation this happens. Has anyone heard of or solved this kind of situation before?

Getting zero-byte .htm files can be caused by downloading a file over an insecure HTTP link from a secure HTTPS page (i.e. mixed content is on the page) or by Firefox sending a HTTP background request in HTTPS-Only mode and "dom.block_download_insecure = true" You can try:

  • about:config => dom.security.https_only_mode_send_http_background_request => false

You can open the about:config page via the location/address bar. On the warning page, you can click "Accept the Risk and Continue"to open about:config.

Dude, same thing has been happening to me for past week, since last update that happened on 23th.

I googled this problem, and it has been happening to people during last 6 months, so we are not only ones. It is pretty rare. Conclusion that this people made has been that it is a Firefox bug.

Do you by any chance got logged out of most websites as well? This happened to me today, about 2 hours ago. Not sure if a bug a virus, but couple of programs that I used have not found anything.
