Chromebook Chrome settings for Browser category suggest 5 search engines (Google Chrome set as default); Firefox (subversively) is not listed. To add it, and make it the default browser in Chrome settings (I made Firefox default in Firefox settings but the preference did not carry over), you must go to the ADD Search Engines category and type the precise Name and precise URL -- what should we Chrome emigrants put on the Chrome side for Firefox for Mobile 7.1?? for Chromebook? I downloaded Firefox traditional after repeated efforts with both that and Android Beta, and and don't find much in support for Chromebooks that are not Android and don't have settings/menus like Android. Firefox developers should obtain a load of factory-refurbished ACER R11's (cheapest touchscreen) for testing and for documenting for us documentation-forgotten souls (Chromebooks were the fastest growing market segment and are acquired in the schools down through the third grade, so such labor and materials would be a well-spent investment). Google's newly augmented and "customized" (for whose benefit?) URLs are concerning.
