Note: This article was published in September 2018, and since then, the mentioned changes have been canceled. I have also switched to Edge.
I don't know when it started, but the address bar of browsers will hide the "http://" protocol by default, while the green lock version of "https://" will remain visible.
Although it is an important part of the URL, we rarely need to pay attention to the protocol name.
When manually entering a URL, we rarely type it specifically because the browser will autocomplete it. In places where manual input is not possible, we use copy and paste or bookmarks. We don't really care whether the protocol is included or not, it just happens to be automatically included most of the time.
However, the part following the protocol name, which is most commonly referred to as the domain name, such as "www.bilibili.com", "www.zhihu.com", "www.baidu.com", is often the same when accessed in a browser with or without the "www.".
For copy and paste scenarios, whether there are four extra characters or four fewer characters doesn't matter. However, if we compare the number of times this part is manually entered to the protocol name that has a very low presence, we can imagine the magnitude of the difference... Well.
Because of long-standing habits, the "www" subdomain and its root domain are used together. Although it can't be considered a problem or an impact when distributed to each individual, I still struggle for a moment and choose to use the "www" subdomain when naming website folders and databases...
Google's "attitude"? Or maybe no attitude at all--
Regardless of the purpose, idea, or consideration, Google Chrome 69 has invested its attention and action in this seemingly "can remain unchanged" area.
↓Firefox↓
↓Chrome↓
In the new version of Chrome browser, not only the protocol name but also the "www" subdomain is hidden by default...
It is reasonable to say that this is a small change in the entire version update, although it is more easily seen directly, although it directly led to me writing this article, although it may cause trouble in foreseeable subsequent use (such as confirming the effect of 301 redirection).
Although my own perspective is completely unrelated to software technology and experience...
