Chrome’s Canary release brings a long-awaited feature: tab pinning. On Android, you can lock key pages to the top of the tab switcher for quick access and avoid accidental close.
Pinning tabs works similarly to desktop Chrome, but with added benefits. Pinned tabs maintain your browsing context, so you don’t need to worry about restoring it when opening new tabs. This feature is now live in Chrome Canary on Android without any feature flags, making it easily accessible.
