web.archive.org unofficial WaybackMachine extension

With a click of a mouse, the extension uses web.archive.org's internet archiving Wayback Machine to view the current website you're on in the year and month you specify.

If the website you're viewing wasn't crawled by the machine at the specified month or year, it takes you to the nearest crawled version and opens it in a new tab.
