Searching had been never so easy without google and now this Addon 'Customize Google'makes it even better. 'Customize Google' lets you customize many features of Google Search. It lets to block the Google ads in almost any Google Page also including Gmail(I loved this one). It remaps Google Images search results to point directly at the images (no longer will you need to click through the originating site). Customize Google lets you add links from other search engines directly into your search results. It can also block Google click tracking and allows you to connect to Google Calendar and Gmail securely (https).
Have you tried the Microsoft's SkyDrive? Here's the one from on your Gmail to store your files(although there is Gdrive on the line). This is not provided by Google but is provided by third party as an add-on and connects to Gmail drive as a new network share on "user's network station".
