A few days ago, after a Firefox Update (I think), I discovered that my Homepage and default search engine had been changed from Google.co.uk to Google.com. Now every time I open Firefox I have to search manually for Google.co.uk before I can search for anything else. Google.com does not work if I enter anything else in the search box. I've been going round in circles trying to work out how to change it back again, but nothing I've tried has worked. Help! Peter
