Remove in Firefox new tab

To remove
1) type  about:config in the address bar and press Enter, there is a warning message about `promising careful`` and click it
2) The list is quite long. In the search bar, type browser.newtab.url to narrow down the items only containing ``browser.newtab.url``.

to new address, such as

another options:
(i) Page thumbnails (default)
browser.newtab.url = about:newtab
(ii) Blank tab
browser.newtab.url = about:blank
(iii) Built-in Firefox home page
browser.newtab.url = about:home 
5) You do not need to restart the Firefox. Open new tab, now the default 
website for new tab is:
