Google Preview is an extension for the Mozilla Firefox browser that is used to display screenshots of a web page in the form of thumbnails within the list of results of your Google or Yahoo searches.
This allows you to immediately access a preview of the website, without having to enter it. Once the program is installed, the thumbnail previews will be displayed automatically in each search you carry out. It also has support for search previewing on Amazon and other sites.
Google Preview is a completely free tool and does not take up a significant amount of disk space: just 20 Kb. You won't even notice that you have it installed.
You can free download Google Preview 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
