After complaining that
Microsoft has made choosing a browser other than its own Edge too difficult with Windows 10, Firefox officials have taken browser-choice into their own hands.
Firefox 40 for Windows 10, made generally available on August 11, includes new "support materials to
show you how to restore or choose Firefox as your default browser in Windows 10."
The new Firefox for Windows 10 goes further. When Windows 10 users look to the Cortana search box built into the task bar, web searches done from that search box will "show results in the default search engine you choose in Firefox," rather than defaulting to Bing, Firefox officials said.
