Why is 127.0.0.1 used for a computer's localhost address?
The Internet Protocol address 127.0.0.1 is a special-purpose IPv4 address and is called the localhost or loopback address. All computers use this address as their own, but it doesn't let computers communicate with other devices as a real IP address does.
The loopback address is only used by the computer you're on, and only for special circumstances—unlike a regular IP address that transfers files to and from other networked devices. For example, a web server running on a computer can point to 127.0.0.1 so that the pages are run locally and can be tested before being deployed. For more information and to discover why that "Home" number may have been chosen, see this early discussion.

New Privacy Controls for Maps, Assistant, Youtube
The first change is to Google Maps, which is now getting an "Incognito mode." This works similar to the Incognito mode found in the Google Chrome browser.
Once activated, Incognito mode means details of where users search for will no longer be saved to their account and won't affect personalized experience. However, while in Incognito mode, users won't see any personalized information such as automatic updates on their commute.

Vivaldi makes web browsing more efficient
Vivaldi launched in 2015 to make up for the loss of features in other browsers. From the very beginning we’ve focused on building our own, highly customizable UI.
We often get asked about the relationship between Vivaldi and Google Chrome. The truth is, while we rely on the Chromium engine (maintained by the Chromium project set up by Google), this is where similarities end. Let’s take a look. Below the UI of a browser – the part most people see and interact with – there’s a rendering engine responsible for displaying the requested content in the browser window, as well as a browser engine responsible for bringing together the rendering engine and the application’s UI.
Different browsers use different engines and when it came to picking ours, we found that the Chromium engine code was secure and the most widely used – things that were important to us. Other pieces of code were either unavailable or undergoing significant re-writes. Developing a new engine from scratch would not have allowed us to focus on what mattered to us the most – it would have taken far too long to do and required significant resources. There is a reason why no one has built a new engine from scratch in 20 years.
