For eg: open email@example.com in one window and firstname.lastname@example.org in another Separate personal stuff and your work stuff Allow your family member to login without you signing out These are the main reasons I use multiple profile in google-chrome.

For case in point you are browsing facebook.com and your sister wants to open the same site for quick check, you can either open different browser or open the same browser that has different profile. (or open in private mode too) Both my favorite browsers Chrome and Firefox supports multiple profile. For now I'll write instructions for Chrome: Right click your panel, select add to panel and select custom application launcher (if you want to add in panel) or Right click the menu , se
Is your Android market giving you problem? And by problem I mean while installing apps it will download all the way but fail to install saying "Download Unsuccessful". I really don't know what causes this "download unsuccessful" error in Android market. But the fix is very simple and as follows: Go to Settings - Applications -Manage Applications Choose Download Manager In Download Manager option choose "Clear data" If "Clear cache" is not disabled clear cache also. Do the same for "Market" which you will find in similar way in Settings - Applications -Manage Applications If you can't find any of the above app, they may be hidden by filter. Its available under "All", not "Downloaded".
