How do you tell Microsoft that you do not like their new web browser?

not using it is a good start.

Three dot menu > about > send feedback 

Even if you do send feedback they probably won't listen.  A better way to show them would be not to use that software, you don't have to and one less user actively using Edge is going to send them a message, I certainly am not going to use that crappy web browser, good for edge for not having linux support like Chrome and Firefox do!!

If you really want to do what Ducky said. 

It's honestly pretty pointless. The good part, though, is that the new Edge is an optional download (unless the new feature update changed that, I haven't checked).

It and Chrome (which is still the best option) are based on the same engine.

You can send feedback using the feedback hub app https://support.microsoft.com/en-us/help/4021566/w...
