This is where the Resurrect Pages add-on for Firefox comes into play; it does its best to make this happen for you. This add-on searches through five big cache/mirrors in order to find that specific web page. In many cases, it can resurrect dead web pages in a snap. Once installed, if you come across a web page with a “net error” page, you’ll see options on the right side to resurrect it. However, you can also use the right-click context menu to resurrect a page, as well as to view the page at an earlier date (using The Internet Archive). Resurrect Pages Add-on Image Credit: CyboRoZ
