TLDR: This app helps find a web page when it cannot be found on the original site.
NotNotFound (NNF) automatically redirects you to a cached version of a webpage when you encounter any error while browsing the web. 404 Not Found, server errors, and other web interruptions won't stop you from finding the content that you need.
Our Recursive Cache System currently checks through Google Cache and Archive.org's Wayback Machine. If the page cannot be found in either cache, you are taken to a page with further caches to manually check.
-webcitation.org cache lookup (coming soon, version 0.5)
-ability to exclude a page/domain from the extension (coming soon, version 0.5)
-automatic bing.com cache lookup
-automatic gigablast.com cache lookup

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.
