Chrome tests whether “Chrome/100.0” User-Agent will cause website errors
In order to deal with the alternative millennium bug problem, Mozilla began testing to modify the Firefox browser version to version 100, and then visited a large number of websites for testing.
The reason for this test is that the UA string of some browsers will contain the browser version, and some websites will return different content based on the browser information.
If there is a problem with the processing mechanism of the website, it may cause an abnormality after the version number is upgraded from 2 digits to 3 digits. In fact, the test shows that there is indeed an abnormality.
During the test, Firefox engineers found that the well-known website Slack had abnormalities, including some buttons that could not be clicked, messages that could not be displayed, and other abnormal situations.
In terms of version update progress, Google Chrome will actually reach version 100 soon, and the Chrome 100 stable version is expected to be officially launched at the end of March 2022.
So now Google Chrome is also beginning to test this issue. Google Chrome tries to modify the browser version to version 100 and then collect website visit information.
Of course, this may still have to rely on user feedback, because some abnormal browsers may not be found through automated testing, so they cannot be fixed in time.
If you are interested, you can install the Google Chrome Canary version, visit chrome://flags and search for “user agent”, in the dropdown for “Force major version to 100 in User-Agent” select Enabled and restart the browser.
Therefore, Google may directly remove any information such as the browser version number in the future, and even prohibit the website from identifying the user through a computer or a mobile phone.
