It seems by what I can tell that you are experiencing a driver issue with graphics care. Please update your drivers or uninstall and re-install your drivers to get rid of error messages that I see. This could be the issue you are having. Please read this https://support.mozilla.org/en-US/kb/upgrade-graphics-drivers-use-hardware-acceleration

If this works please remember to let us know and to mark this as solved please. If needing further help please post telling us that you have updated and what further issues you may have. Thank You

Hi   !

Just in case the above doesn't solve the problem :

Would you please disable   Kaspersky   and see if that makes a difference   ?

Yes, Thank all you, i disable Kaspersky then i see i can connect normally

Hi! Kaspersky here :)

Couple of questions so I can raise this my support team:

• Which version of Kaspersky are you currently running? (Internet Security 2017/ Total Security 2016, etc)
• Which version of Windows are you running?

Thanks! :) ^David.
