Now in the Play Store appeared Chrome Canary is the least stable and experimental version of a browser.
The number of errors and defects, is superior to Chrome Canary Stable, Beta and Dev together. If the last two can be played impatient geeks, the "Canary" is designed for experienced developers, consciously running the risk.
Canary – advanced version, so new features will appear there much earlier. However, the quality of work will leave much to be desired.
