ChromeOS 135: Discover New and Removed Flags for Enhanced Browsing (Updated)

Want to peek under the hood of ChromeOS? Google regularly tweaks experimental features, accessible via chrome://flags, to improve performance and introduce new functionalities. Upgrading from version 134 to 135 brings a fresh set of changes. Let’s dive into the new and removed flags in ChromeOS 135!

Please note: These are experimental features! Enabling them could lead to data loss, security vulnerabilities, or privacy risks. It's best to back up your data before experimenting. These flags apply to all users of the browser and should not be used in a production environment if you are a company administrator.

What are Chrome Flags?

Chrome Flags are experimental features in the Chrome browser and ChromeOS that aren't yet ready for the general public. They allow developers and enthusiasts to test out upcoming features and provide feedback before they're officially released. Access them by typing chrome://flags into your address bar.
