Google Voice Search Never Works
When I started to use Vivaldi, I noticed that the voice search for Google never seemed to work and I just hated that this browser which I believe is chrome based cannot even utilize the voice search option on Google.
What happens is that the voice search says its offline when there is clearly a connection to the internet in this screenshot below:
As you can see there is a connection to Wi-Fi down below but Google's Voice Search never knows that it is online and you can see in the address bar that permissions are given to Google.
Problem already known and in the list of bugs to be solved!
