I cannot reproduce your problem, I know that some add-ons cause this, but you said that this is a fresh profile, so I have no idea how to reproduce. What is the location bar input field value when you click on the address bar?

I am surprised that you say you cannot reproduce the bug. I can reproduce it every single time on Windows 10 x64, Windows 7 x64, and Mac os Sierra. I have attached a video here to show you the bug which I have recorded on a freshly installed Windows 7 in VM. https://dropfile.to/ErgUGdt Please leave your development environment and use a fresh environment as I have displayed in the video, I'm sure you will be able to reproduce. 1- Go to any web page 2- Click on any link to go to another web page and wait for it to load 3- Click on the location bar (as if you want to enter a new address) and just press "Enter" Firefox suddenly moves to the web page in step 1, instead of refreshing the current web page. I'm a Software Engineer and I can assure you this is a real bug, and it is very annoying.

Yes, I agree this would be an high priority bug, but I still cannot reproduce, I wonder if it involves something more that we are missing (For example, I'm in another country and the yahoo page differs). Does this happen on any webpage, or mostly on this Yahoo page? Drew, can you reproduce this on any of your systems?

Brindusa, can you help us to reproduce this?

It's a dupe of bug 1334844.

It happens on any web page (as I mentioned in my comment) and every single time.

I can't reproduce this or bug 1334844 either.

Can you find a regression range using mozregression if you can reliably reproduce this?

let's dupe for now, but feel free to report here or in the other bug whatever may be useful to us to moving this forward (regression range would indeed be useful)

Btw, there is indeed a possible bug involving CTRL+ENTER, so would be nice to know if yo uused CTRL+ENTER to visit the first page.

Very interesting! I can confirm that the bug happens when visiting the first web page with Ctrl+Enter, but the bug DOES NOT happen when entering the url manually!

The bug is not resolved! I'm so frustrated that you all say that you cannot reproduce the bug! :-(

NEW DEVELOPMENT! NEW DETAILS DISCOVERED ABOUT THE BUG! PLEASE READ! Steps to reproduce: 1- Launch Firefox (Fresh install, No addon, history cleaned) 2- Enter "google" in location bar and press Ctrl+Enter and wait for the page to load 3- Click on "About" link in the bottom of the page and wait for the page to load 4- Click on the address bar and press "Enter" Note: google is just an example. The bug happens with any web page that after pressing Ctrl+Enter does not redirect you to a different URL. For example if you enter "ibm" and press Ctrl+Enter you get automatically redirected to "http://www.ibm.com/us-en/", NOT "http://www.ibm.com/", which makes the bug not happen. But for any other website that if you enter "domain" and press Ctrl+Enter and you are directed to "http://www.domain.com/", the bug definitely happens as I described here. So if in your particular region after entering "google" and pressing Ctrl+Enter you get redirected to any web page other than "http://www.google.com", please find another web site. Actual results: Firefox goes back to https://www.google.com/ !!!!!!!!!! Happens in Firefox 51.0.1 and Firefox Developer Edition 53.0a2 on Windows 7 x64 and Windows 10 x64. Doesn't happen on previous versions of Firefox. Expected results: Firefox should refresh the current web page https://www.google.com/intl/en/about/

There is no new details there, so no reason to reopen

Are you still unable to reproduce?!?! Did you read my new comment? Did you read the important "Note" part? That is why you weren't able to reproduce with yahoo.com
