ESR31: about:tor shows "Tor is not working"
When running within an ESR31-based browser, the about:tor page always shows "Tor is not working in this browser". This happens because the mechanism Torbutton uses to detect load of the about:tor page has been removed from the Firefox code (specifically, the BrowserOnAboutPageLoad() function has been removed from browser.js). Kathy Brade and I are working on a fix.
