A statement from the company said Vivaldi 3.3 also had a new default them for using private windows, base domain highlighting, clickable parts of URLs in the address bar, and an improved tracker and ad blocker.
The Break Mode had been introduced to boost health and productivity and helping people to switch off.
“We want to give our users the tools they need to stay productive, but we also want to empower them to manage their time and balance all the things that are important to them”, Vivaldi chief executive Jon von Tetzchner said.
"Easily triggered with a pause button at the left corner of the Status Bar, Break Mode mutes and stops HTML5 audio and videos, hides all tabs, panels, and other content leaving the screen clean," the company said.
"Alternatively, Break Mode can be activated with Quick Commands or its shortcut Ctrl + “.”
"Once the browser is paused, users can interact with the physical world – communicate with their colleagues or loved ones, make a phone call, jot down those creative ideas on a piece of paper, exercise, take a power nap, or grab a cup of coffee in peace."
The base domain highlighting feature is meant to help users clearly see the URL of a Web page that is malicious.
