Google is preparing to release a new Chrome update which will give users one of the most requested and most complained about feature that is missing from Chrome, user-created extensions or add-ons.
"Chromium can't be everything to all people," according to the extensions document.
"User-created extensions have been proposed to solve these problems: the addition of features that have specific or limited appeal; users coming from other browsers who are used to certain extensions that they can't live without; bundling partners who would like to add features to Chromium specific to their bundle."
While Google is in the very early stages of developing the new extensions, the survival of Chrome depends on it. I would expect to see this release in an update in a few months.
