Chrome/Firefox: Google’s Chrome browser and Mozilla Firefox both offer lot of built-in tools to manage or erase your browsing data. If you need more control, Click&Clean can help you out.
The extension allows you to automatically clear your data every time you close the browser, manually browse through your cache, and add a “Forget this page” button to the context menu. The extension also provides quick links to some of your browser’s more useful, if hidden features, like Chrome’s memory manager and experiments page.
