Just updated and I'm happy so far, everything seem to be working OOTB! ;)
Good to see a new one.. I was having issues with 3.9-10... Scrolling with the mouse within Iceweasel caused CPU spiking that caused lags that sucked... I have seen this same thing in past kernels
Will let you know if it resolves it once I update
3.9-11 has corrected the issues I was having with scroll and mouse movement in Iceweasel...
Same issues here with the scrolling. -11 has seemed to correct it as VastOne says! Everything working OOTB for me as well. 8)
