Windows 10 1803 default browser

Long ago MS stopped people using any browser but theirs from the Cortana \start menu\ taskbar search box- just search the internet for
'Cortana search browser' and you can read all about it.

However, I saw this recently which may help:

Let us know if it works for you.

Otherwise, yes, you should be able to set your chosen browser as default for file types, protocols so clicking on links opens your default browser. (Note- I have build 1709 as you can see from my specs).

How to Make Cortana Search with Google and Chrome Instead of Bing and Edge

I have 1803 and it astounds me that the default browser selections include only Microsoft Edge, Internet Explorer & look for an app in the store.

I have 1803 too, and on the two machines with Firefox installed it appears along side Edge and IE in that selection box.

But the OP wasn't asking about the default browser - they are asking why, whatever browser you set as default and whatever search engine it uses by default, the results from the Cortana/Search box on Start are always Bing in Edge. This is by design...

Microsoft have apparently blocked all the previously known ways of weaning Cortana from Edge/Bing, saying last April... {edit: that was April 2016}

...The only way we can confidently deliver this personalized, end-to-end search experience is through the integration of Cortana, Microsoft Edge and Bing – all designed to do more for you.

Starting today, to ensure we can deliver the integrated search experience designed for Windows 10, Microsoft Edge will be the only browser that will launch when you search from the Cortana box.

There is of course nothing stopping you opening Firefox and searching with Google, just not from Cortana.

The one and only concession is that you can still choose to launch IE instead of Edge from Cortana.

How can I make Cortana use Firefox and Google search engine?


PS: I have tested that in 1083 you can still choose to get Cortana to launch IE.

Although I saw some post including Cortana/Search box mentioned in some posts, I didn't see the OP mention he wanted to keep Cortana active in his original post...

The original question had two parts to it. From post #1...

I would like to use Firefox but I cannot find a way to set it as default browser, in particular when I open a search result from "start menu" Edge is fired up instead of Firefox; i searched but i'm not able to find a solution.

The OP's main problem was stated as an inability to set Firefox as the default browser (which you seem to suffer, but I don't). The OP then talked of the browser that launches from a Start search result (which is where Cortana comes into this, she does the Start searches). That's not related to setting a default browser, Cortana/Search results will launch Edge whatever your default browser is set to.

By post #3 the OP's focus had switched to the Search results...

That Setting is not enough, It is already in use and configured to use firefox, Edge is opened insted of firefox to display start menu search results.

As Microsoft stated in April 2016, by design it is no longer possible to choose which browser launches from Start's Search (aka Cortana),

...The only way we can confidently deliver this personalized, end-to-end search experience is through the integration of Cortana, Microsoft Edge and Bing – all designed to do more for you.

The solution Dalchina offered in post #12 is to use a third party utility that intercepts the call to open Edge...

EdgeDeflector is a small helper application that intercepts URIs that force-open web links in Microsoft Edge and redirects it to the system’s default web browser.
