Chrome is a fast, simple, and secure web browser, built for the modern web. Chrome is designed to be fast in every possible way. It's quick to start up from your desktop, loads web pages in a snap, and runs complex web applications lightning fast. Chrome's browser window is streamlined, clean and simple. For example, you can search and navigate from the same box and arrange tabs however you wish -- quickly and easily. Chrome is designed to keep you safer and more secure on the web with built-in malware and phishing protection, auto-updates to make sure you have all the latest security fixes, and more. Chrome puts you in control of your private information while helping protect the information you share when you're online. There are tons of ways to customize Chrome and make it yours. It's easy to tweak your settings and add apps, extensions, and themes from the Chrome Web Store. Signing in to Chrome brings your bookmarks, history, and other settings to all your computers. It also automatically signs you in to all your favorite Google services.
Passwords Not Saved Between PCs By Default: Google Chrome stores passwords in such a way that they are encrypted in a way tied to current PC. While the passwords are not kept or left behind on the PC itself, they won't be retrievable when you move to a new PC. There is added password portability as an advanced option, though, which you can enable by reading the help.html file.
Certificates Not Portable: Google Chrome has no certificate manager. It uses Windows' certificates manager. So, any certificates you install through the Google Chrome interface are stored on the current local machine and will not travel with you. Thus, you should not use any private certificates with Google Chrome except on your own PC.
Some Settings/Extensions Locked Per PC: Google Chrome locks specific settings to a given PC. Details are included in this post. This behavior is by design by the Chrome team. If you would like this changed, please file a bug with the Chrome team. A suggested workaround is to sign in to Google to restore all settings and extensions and to use an extension such as Session Buddy to maintain your session state as you move PCs.
Note that other portable browsers such as Mozilla Firefox, Portable Edition do not have any of the issues mentioned above. These issues are specific to Chrome due to Chrome's design and not something we can work around without fixes to the base app by the Chrome developers.
