I closed all the TABS, went into tools/clear private data and cleared cookies, cache, history and offline web data and then closed Firefox completely.

My History under tools/options/privacy is also set to ZERO days.


But if I open a new Firefox browser and when I click on the down arrow in the Address Bar, I get this:



the ones in red are the pages I visited previously and this shouldn't be showing because I cleared all private data.

the ones in blue are pages under my bookmarks that shouldn't even show because I haven't visited them in a while.

if I highlight each one of them in blue with my mouse and keep pressing the DELETE button, they will go away but as soon as I click on the down arrow again, they are there again.

How do you make them disappear permanently?

This means I can clear everything, close Firefox and if someone were to open it, they can STILL see where I been and what's under my bookmarks.
