http2 profile and Firefox

Question

Hi,&nbsp;
I just started to play with http2 and spdy. Both profiles are working when Chrome (42.0.2311.135 m) is used. When tested with Firefox (37.0.2) is used only spdy profile is working. With http2 profile I am getting empty page.&nbsp;
In HttpWatch I can see first GET request with result NS_ERROR_ABORT.&nbsp;
I wonder if this is only my setup or there is some general issue with Firefix, F5 and http2 - will appreciate if someone could check/confirm.&nbsp;
Test was done using 11.6.0HF4 and default http2 profile. VS is as well using AAM Web Acceleration profile but this is working OK on both Firefox and Chrome when http2 is not enabled.&nbsp;
I wonder as well how LTM is handling browser requests when both http2 and spdy profiles are used. Is there any fallback mechanism based on browser agent reported - like if browser is not compatible with http2 use spdy, if both http2 and spdy are not supported use http 1.1?&nbsp;

Is it possible a non-TLS cipher is being negotiated prior to the GET request? Firefox only supports HTTP/2.0 use over TLS connections? Worth checking.&nbsp;

Thanks, will check https handshake, could be the reason.

Hi,&nbsp;
Checked ssl handshake. Negotiated cipher is TLS_DHE_RSA_WITH_AES_256_CBC_SHA.&nbsp;
After server is sending Change Cipher Spec (over TLS 1.2) client response is FIN, ACK.&nbsp;
So it seems that this is not non-TLS cipher issue. Any other ideas?&nbsp;
