5.Seach Engines Cached pages
If you want to view the relatively newer version of any website, you can view the pages cached by search engines.
To do so, search the page you want to see, click the drop-down arrow beside the result’s URL, and click on Cached. The search engine will then display the latest cached version of the page instead of the live one. On Google, you will view Cached after clicking on the three-dot icon.
6.Web Cache Viewer
This extension makes viewing old website versions much simpler. Just head on to the website whose older version you wish to see, right-click on the screen, and choose Web Cache Viewer. The extension opens a new window showing the last cached page.
Although this extension pulls the snapshots from Internet Archive and Google Cache and has no record of its own, it allows you to view web archives easily.
