My Firefox browser language is set to english (UK) When I go into private browsing mode, the first search screen correctly displays in english. However, after inputing a google search term, the next screen to display is the Google screen headed "Before you continue to Google search" and asking to Agree, bu this is in language NL (Netherlands). I am able to change the google language option to english, but the search criteria results in may instances of nL websites being found. What have I to do to reconfigure Firefos and/or Google?

Thanks
