- Based on Webkit, but using a custom regression and testing system.
- OS-level address separation between the loaded sites/tabs. This is described as running multiple processes, so you get the full memory and system resources back after you close the tab.
- Processes run inside a sandbox with varying trust levels for extra protection. The browser includes a process manager.
- Since plugins cannot be sandboxed efectively they run inside a dedicated process .
- Google Gears is included by default.
On the user interface side:
- The address bar is below the tab bar like in Opera.
- Full drag and drop, detachable tabs like in Safari.
- Fancy completion support in the address bar.
- A tiled view for new, empty windows/tabs, similar to Opera.
- Popups are launched in a minimized state inside the tab that created them, and can be dragged out when needed. This alone could be the killer feature for Chrome.
Update: official announcement of a beta version:
We will be launching the beta version of Google Chrome tomorrow in more than 100 countries.
