Revive Pages is an extension for Firefox (up to version 57), Seamonkey, Pale Moon, Iceape-UXP and other browsers that support extensions created using XUL overlay technology, intended to solve this task by using of dedicated Web sites (mirrors), which hold copies of other Web sites.
In order to do this, it adds to the standard browser Error page its own buttons with which you can try to open a copy of the page saved in one of these archives:

Apart that, it adds a new menu item for this operation to context menus of web pages and links on them:

Identical items it adds to context menus of the Page Source window and links in it:

And yet one "Revive this page..." menu item it adds to the "Tools" menu (if this is not disabled in the extension settings).
Also during browser UI customization you can drag extension button to any of browser panels:

By clicking on any of the above-mentioned elements you will open a window for selection of the desired archive:

Revive Pages is very similar to the famous Resurrect Pages extension, but have some advantages over it. Most important of them:
- Revive Pages works not only in main browser window, but in Page Source window too.
- Revive Pages dialog does not block browser, you can open it and continue browsing without necessity to open archived page immediately.
Moreover, you may keep as many opened Revive Pages dialog windows simultaneously as you wish.
Also I hope it will be available soon at https://addons.palemoon.org/addon/revivepages/
