For many, many years Firefox has been my default browser. Even now, when Mozilla has ruined the Android version I have persisted, but it's got to the point I have to give up. Several weeks ago I visited Paris for six days and now Google in Firefox for Android has decided I'm French. Everything in settings is set to UK English and locale to current, in both Firefox and Google. On my laptop everything is fine, but on my phone all google results (although in the English language) are from France and shopping results in Euros. I have deleted the app, I have cleared the data, I have re-installed multiple times, but nothing has worked. All other browsers work fine, with the correct results from UK and in pound sterling, but in Firefox for Android it's France and Euro's. Is this some mind experiment?
