about:home search is broken
In Tor Browser, the search feature of Mozilla's about:home page does not work. Clicking the Search button does nothing. There are multiple problems:
Mozilla uses LocalStorage to pass info about the default search engine to about:home. They only set the info once (during browser "first run") and since the Tor Browser does not write LocalStorage to disk the info is lost.
The about:home search code does not support engines which use POST (Startpage is configured to use POST).
Should we remove about:home from the Tor Browser? Should we fix these problems (probably not too difficult now that we know what they are)?
