After browsing the web for a while, I want to delete my history. So I press CTRL and H keys, and click the Edit items on the blue bar at the top of the page. Then I select the checkboxes for the items I want to remove. Then I click remove selected items.

When I go into any of my open tabs, their history isn't deleted.

Without restarting the tab or the browser, is there any way to clear the history within a tab?

I also want to know how to clear just one tab's history, without needing to know all the pages that the tab had visited, then going to the history page...
