Google shared details on a recently introduced Chrome feature that changes how cookies are requested, with early tests showing increased performance across all platforms.
Modern browsers like Chrome use multiple processes to improve performance and security.
This allows Chrome to check if a cookie has the latest data without making repeated requests.
According to Google engineers, this change has reduced the number of cookie-related messages by 80% and sped up cookie access by 60%. "The idea is that each value of document.cookie is now paired with a monotonically increasing version. Each renderer caches its last read of document.cookie alongside that version," Google explained how the feature works.
Google Chrome change that weakens ad blockers begins June 3rd. Google rolls out Chrome fix for empty pages when switching tabs.
Google Chrome is getting native support for YouTube-like video chapters.
