How'd I Get Here? - firefox addin

Use this extension to go to the page on which you first clicked a link to the current page. For example:
Go "back" even after opening a link in a new tab and closing the original tab.
Remember how you found a site you bookmarked yesterday.
When you are sent a link you have already seen, astound the sender by responding with a statement more precise than "I saw that on some blog a few days ago".

This extension does not work in Firefox 1.0

So I will test it later

Seems to be a nice find!
