User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:75.0) Gecko/20100101 Firefox/75.0

Steps to reproduce:

When clicking the new address bar, it shows a list of shortly visited sites, bookmarks and open tabs.

This is a privacy concern, since now at every click at the address bar, part of my history/bookmarks are shown.
This means clients I use my computer in front of at my homeoffice or colleagues (when I bring in my private laptop) might see them too.

Actual results:

When clicking the new address bar, it shows a list of shortly visited sites, bookmarks and open tabs.
One can deactivate search in history, bookmarks and open tabs "about:preferences#privacy", but then neither the list will be shown, and there will there be no search on typing.

Expected results:

Either the results should populate only at typing (as it was before), or there should be an option to disable this separately from the existing options.
