As you know, luakit is fast browser based on webkit engine and I want to use it for TOR. Unfortunately luakit publish a very unique useragent and http_accept headers. This problem can be solved by adding two lines at the end of ~/.config/luakit/globals.lua
globals.useragent=("Mozilla/5.0 (Windows NT 6.1; rv:24.0) Gecko/20100101 Firefox/24.0") --Like a TORbrowser
soup.accept_language ="en-us,en;q=0.5" --locale language like a TOR
