I had tested this issue on Windows 10 x64 with latest Firefox Release(57.0.4) and the latest Nightly (59.0a1-20180116220110) and haven't manage to reproduce the issue.
On a website in the search bar (google, youtube), after typing any word or characters, when search suggestions are displayed if a suggestion is selected using the mouse, the corresponding webpage is displayed.

Here's a screen recording: https://goo.gl/bHbt9r

Can you please retest this using a new clean Firefox profile (https://goo.gl/x4EdXd), maybe even safe mode, to eliminate custom settings as a possible cause (https://goo.gl/fPLNDn)? Could you also test this using the latest Nightly build (https://nightly.mozilla.org/)?

I found the cause of this problem. It is an installed and activated extension that causes this problem.

I have disabled all extensions of Firefox and I will activate one by one the extensions to find the faulty extension of this problem.

Thank you for your reply and sorry!

I'll give you the name of this extension. I'm doing the tests now.

I ended up finding the extension that causes this problem: 

Enable Right Click and Copy  - Version 2017.4.12
https://addons.mozilla.org/en-US/firefox/addon/enable-rightclick-and-copy/?src=api

Thank you for finding the extension. Normally we don't support third-party extensions, however I'm concerned that this one could be using an API that needs fixing, or there's something being injected in too many places - since the search results shouldn't be affected.

Hence moving this to WebExtensions, so they can take a look at what is happening.

This extension injects a content script that installs event handlers for mouseup and mousedown among other things.  I believe everything in the browser is working correctly and this is a bug in the extension, your best bet is to report this to the author of the extension.
