New Tab Customize Option missing in Edge
You have two options to fix this issue:
Reset Microsoft EdgeCheck your Hosts file.
Reset Microsoft Edge
Backup your Favorites, etc, and reset the Microsoft Edge browser and see if that helps.
Check your Hosts file
What helped me was this. To make Edge load faster I had added the following entry to the Hosts file and that was the issue: You may need to edit the Hosts file. So open your Hosts file using Notepad which is located at: If you see this entry, delete it. You may use HostsMan to edit the Hosts file, or simply remove it via Notepad. If you are unsure, you may simply reset Hosts to its default format.
Having done that, restart Edge and see. It should be back! Reads that may interest you:
