Well guys, If you're a Firefox user you have quite a few choices. The Remove/Hide Gmail Ads user script should work in both Firefox and Chrome without requiring you to install an entire extension. It'll hide ads all along the side and top of your messages, without getting rid of Gmail's new contact info. So, you won't be able to save any of that white space, but at least everything will look a little less cluttered.
You can install the Ad-Blocker for Gmail Chrome extension, or the Gmail Ad Remover extension for Firefox.
And now there is adblockplusandroid, you can install this apk, and get rid on ads on your android, its is not yet proved to be the considerable but you can try.
