Option to disable welcome screen

### Issue Details

Wanting to implement Adguard extension to protect several users, however if I push the extension to users devices they all get the Adguard welcome screen opening which causes unnessesary confusion. Is there a way to not display any welcome screen to make it easier for organisations to deploy it across multiple devices? Even better would be a way topush out some pre-configured options but I'm not sure if modern browsers would allow that.

### Proposed solution

Allow disabling the initial welcome screen and load the extension with it's standard defaults.

### Alternative solution

Provide a way to push configuration settings via intune or other services.
