searching from about:tor brings me to duckduckgo but my query is discarded
Go to about:tor and in the text box in the middle of the window, type foo and then either hit enter or click the magnifying glass.
It brings me to duckduckgo, but it doesn't carry the search query along with it -- I have to do my search query again once I'm at duckduckgo.
Things work fine from a blank tab, or from the little search box in the upper right.
