I have Firefox version 42.0. I get the Firefox homepage, but as soon as I enter my first search I get the browser page from the chosen search engine e.g. Google, Bing etc.. These browser pages have none of the Firefox features. I have tried all the recommended fixes such: Setting Firefox as default browser. Setting up Firefox as a default App in Windows 10 and restoring Firefox. Therefore I can change my search engines but I cannot keep Firefox as my preferred browser even though the home page always opens, it just goes straight into a Google / Bing or whatever 'search engine search I have set. I am coming to the conclusion that this is the way the latest version works but older versions always retained Firefox as the browser.

Any ideas. Ian
