The 'All in one sidebar' (AIOS) is a sidebar control system that was inspired by that of Opera’s. Having it installed lets you gather information on a website, view your active downloads, display a website’s source code and your bookmarks.

It is a useful add-on for the Firefox browser that really sets it apart from internet explorer. It acts as an assistant that can even verify the identity of a website by viewing its security certificate.

The sidebar can be customised with themes and various other extensions, thus allowing the user to add a touch of creativity to their browser.

Overall, the 'All in one sidebar' is a must-have download that will improve both the function and aesthetic of your browser.
