Clear recent history
Some Tor Browser-Bundles ago you could click the button "Clear recent history". You would think that would accomplish nothing, but it indeed does clear the "Recently closed Tabs" and Windows history.
Currently there is no way to clear that list. I have to restart the whole browser bundle or i need to open 10 unrelated tabs and close them to overwrite tab history. This is bad. Either recent tabs are not written into that list or the button to clear recent history should be reenabled.
