Google Chrome 100 Beta Release: Marks the End of User-Agent Strings

Google Chrome and Firefox browsers are about to release version 100, and now Chrome 100 has reached the Beta channel.

In a Chromium blog post, Google wrote: “Chromium 100 will be the last version to support unreduced user agent strings by default (and related navigator.userAgent, navigator.appVersion and navigator.platform DOM APIs). Allows site testing to be fully The Origin Trial for the Reduced User-Agent will end on April 19, 2022. After that date, the User-Agent string will be gradually reduced”.

User-agent strings have been a core component of web browsers for decades, allowing websites to change their behavior based on the browser, browser version, CPU architecture, and other data . Browsers have slowly started to limit the information in user agent strings (eg, all iPhone user agent strings do not include the iPhone model) because they are easily used for fingerprinting. Google recommends using the newer User-Agent Client Prompt API instead, which is more secure than user-agent strings and less likely to break websites.

Chrome Beta 100 also includes some other new features. On desktop platforms there is a new multi-screen window placement API that allows websites to detect the monitor connected to the user’s computer and place different windows on specific screens. There’s also Origin Trials for the Digital Goods API and some new JavaScript features (basically opt-in testing of web features).

In other respects, Chrome 100 will also have new icons, the mobile version of Chrome 100 will remove the data-saving Lite mode, the Android version of Chrome 100 will introduce an optional confirmation dialog that closes all tabs at once, and provide a download information icon on the top taskbar Wait.

On all platforms, Chrome Beta supports running with other versions of the Chrome browser.
