In some SSL enabled websites I see "411 Length Required" error. When I change browser everything works great. It seems, that only Firefox has this issue. Additional text showed in error page:

Length Required A request of the requested method POST requires a valid Content-length.

How to fix this issue? Any ideas?

Your system details show that you have Bitdefender installed.

Another user reported that disabling Bitdefender solved the problem. They then disabled protection and re-enabled it;   problem solved.

Worth a try .....

Sounds that the servers is possibly misconfigured and sends incomplete HTTP response headers.

Can you post a link to a publicly accessible page (i.e. no authentication or signing on required)?


Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window
