Checks webpages for phish based on snapshots of known-good sites.
AuntieTuna is a browser extension that checks if each visited page is a
potential phishing website based on snapshots of known good websites
that a user adds.
For example, a user adds a snapshot of Bank of FooBar. The extension
then checks every other page the user visits to see if it looks like
Bank of FooBar–if it does, it's likely phish and blocked.
