Secure WebSocket (wss://) doesn't work on Firefox
firefox, html, php, stunnel, websocket
Solution
If you work in local with auto-signed certificate, you have to approve it on both servers https:// running on port 443 and wss:// running on port 12345 here with Firefox.
I think your browser does not allow the secure websocket connection and that why some headers are missing.
[Update from @Faisal comments as it is really important] Answer is right but a little bit unclear. Ok here is it. When you would try to open up wss say using wss://mysite.com:12345, Firefox will keep on giving you error until you open up a separate Firefox tab and do try hitting URL [https]://mysite.com:12345 and Confirm Security Exception (like you do on Firefox normally for any https based connection). This is really weird and happens only in Firefox.
Problem
I have a working WebSocket non secure application. But my website uses https and I need a Secure WebSocket connection to avoid Firefox to complain about the fact that the connection is insecure. I am using php-websocket-server for my WebSocket server with PhP 5.2.9, so when i use WebSocket secure i can't decrypt packets with the openssl_decrypt function. That's why i used stunnel in order to decrypt packets sent by the client using wss, to do that i binded client WebSocket to 12345 port an server WebSocket to 54321 port, then i added a stunnel in server mode : ``` [wsServer] accept = 12345 connect = 192.168.1.227:54321 ``` With this configuration my application works fine on Chrome through https + wss. But on Firefox there's a problem during the handshake, it seems that `Sec-WebSocket-Version` and `Sec-WebSocket-Key` are missing in the header. I don't understand because it works on Firefox through http + ws. Thanks in advance for your help. Edit : i added an exception for the certificate on the port 12345, now the handshake is going well because i think Firefox now have the `Sec-WebSocket-Key`. Here the working header request with Firefox (bigger than Chrome request): ``` GET / HTTP/1.1 Host: 192.168.1.227:12345 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:14.0) Gecko/20100101 Firefox/14.0.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/;q=0.8 Accept-Language: fr,fr-fr;q=0.8,en-us;q=0.5,en;q=0.3 Accept-Encoding: gzip, deflate DNT: 1 Connection: keep-alive, Upgrade Sec-WebSocket-Version: 13 Origin: https://192.168.1.227 Sec-WebSocket-Protocol: HyBi-00 Sec-WebSocket-Key: 65nHN33M6drIPjQHcGK8pA== Pragma: no-cache Cache-Control: no-cache Upgrade: websocket ```
