Google I/Oconference held for its developers revealed several  innovations, among those the first day of the conference discussed on extensions for Google Chrome.
For now, this is a limited system, because it exposes all the functionality available and its interface is limited, these extensions are developed using HTML, JavaScript, CSS, so they’re not difficult to write. These extensions do not require to restart the browser after installation,but according to my experience with present 3 first extensions require restarting the browser after installation,maybe this non- restarting concept will be applied to future extensions.

Another thing I noticed is extensions (like page rank) will appear on a bottom bar of the Chrome browser as demonstrated by Boodman, suggesting that the real estate at the top of the browser will remain reserved for bookmarks only, and not add-ons.The buttons that users click on to use a extension will look similar to that of the bookmark buttons. When users highlight their mouse over an extension, it will illuminate the extension, with borders around it to separate it from others.

Google will offer a housing system for extensions, which may be updated automatically. They will also be compatible with future versions of the browser, so there will be no compatibility problems with older versions.
