Like Firefox and Chrome, Vivaldi browser too doesn’t display a website’s full URL in the address bar, it hides the protocol. For e.g. for my site, the URL bar shows ‘techdows.com’, instead of ‘http://techdows.com’. Don’t worry! You can disable this and set Vivaldi to show the complete URL in the address bar, here is how that can be done.
Make Vivaldi to show full URL in Address bar
1. Visit Vivaldi Settings > Address bar
2. Under Address bar options, check ‘ Show Full Address’.
This is one of the changes you need to remember and make when you freshly install or reset Vivaldi browser.
