-automatic bing.com cache lookup
-automatic gigablast.com cache lookup
-suggest related pages if site cannot be found in any cache

Why do we need to access \"Your data on all websites\"?
We look for http headers to check to see when you reach a page with a 404 or other errors. This is the only content that we access while you are browsing the web. We use header and title information to guide you through the caches once you reach a page with errors. The sites you visit and their content are not recorded by this addon.
Additionally, if you're visiting a secure (https) website, we won't be interrupting your web requests, error or not.
