This extension adds a button to your browser toolbar. Click the translate icon whenever you want to translate the page you're visiting.
The extension also automatically detects if the language of a page you're on is different from the language you're using for your Google Chrome interface. If it is, a banner appears at the top of the page. Click the Translate button in the banner to have all the text on the page appear in the new language.

NOTE: Please do NOT try this extension to translate this page or other pages on https://chrome.google.com/extensions. It does not work because Chrome does not allow extension gallery pages to be scripted.
UPDATE(v1.2): Now you can change the extension options to enable automatic translation or prevent the banner automatically popped up for specified languages and web sites.
