Flickering video during playback on YT and FB

If I play a video on MPC its fine, but if i play a youtube video or facebook video it flickers...is there a fix for this as ive literally fresh installed this 2 days ago and nothing but problems with it and thinking about loading my win7 backup back on

running latest nVidia driver

edit: also youtube videos 60-70% of the time wont play straight away and have to wait 10 seconds

system is 3.6Ghz Core-i5 / 8Gb / GTX650 / Samsung 850 EVO 250Gb

if anyone can help I would appreciate it

thanks

Which browser are you using? Ensure flash is up to date if using a browser that doesn't handle this for you.

Hi it was firefox and flash was up to date and even when i removed it to rely on HTML5 it still did it - however i have since clean installed it and all is ok EXCEPT on major important factor...I use DAWs and VST's and my GTR Stomp Box 3 plugin wont work on it and i need it desperatley to addd effects to my guitar in real time (well 0.014 seconds)

gutted gutteed gutted

also the default app option has stopped working and you have to do it the old fashion way by right clicking on the file and "open with" - so windows 10 is probably the best looking but WORST to public release yet....they should stick to 5 years and research it heavily as the BETA testing group is probably small and the real problems only come out when it hits the masses this is why ive waited 9 months hoping they have ironed them out,,,, doesnt look like it

.....continued....seems the video flickering issue is back and i THINK its firefox only as chrome is fine..no flash installed on firefox (does same with it installed) - going to try chrome but i need that plugin to work for my guitar

..well its plagued with issues - setting default apps has to be done the good old fashioned windows 7 way (set default apps or in properties of a movie/music file) as the option in settings wont change to anything for anything...only option that works is LOOK ON STORE

i get the feeling Windows 10 is probably doing this to force users to use APPS instead of PROGRAMS

Old thread but maybe some people will still land here...Go into your Mozilla options->Advanced->General Tab
and disable Hardware Acceleration. Restart browser and try again.
