How to Change the Number of Thumbnails on Firefox’s New Tab Page

Firefox is indeed an awesome web browser. Firefox comes first when someone talks about security, performance and overall stability. Although, some people use Google Chrome for getting faster speed but Mozilla Firefox is not also lagging behind other browsers as this web browser provides a good internet browsing speed. The most important thing is it has better security and private browsing mode than any other standard web browser.
