the awesome thing about duckduckgo is that it can be like a search engine for search engines! they have a feature called "bangs" that let you hop from one site to another just by adding an ! and a letter (i.e. g for google (i.e. !g ='s a google search)) here is how you can use start page: https://duckduckgo.com/bang?q=start I use it all the time to hop from google, to amazon, to ebay, to newegg when I know that is the site I want to use. all I have to do is open a new tab in firefox and then use a "!" (bang).
