User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:38.0) Gecko/20100101 Firefox/38.0 Build ID: 20150525141253 Steps to reproduce: There is a common procedure I'm always doing: 1. Copy an URL to clipboard 2. Ctrl+N (open a New WIndow) 3. Alt+D (Addressbar) 4. Ctrl+V (Paste) 5. Enter Actual results: In IE8 this procedure goes great, but in FF not always it is going well, for some reason there is a Delay that makes problem. Expected results: Please change AddressBar behaviour to be like in IE8.

Hi reporter, I wasn't able to reproduce this on latest release(42.0) nor latest Nightly(45.0a1). The steps you provided are executed as expected(and as you described that works in IE). User Agent: Mozilla/5.0 (Windows NT 6.1; rv:42.0) Gecko/20100101 Firefox/42.0 Build ID: 20151029151421 User Agent: Mozilla/5.0 (Windows NT 6.1; rv:45.0) Gecko/20100101 Firefox/45.0 Build ID: 20151208030212 When opening a new window, you can select from Options -> General what that window will contain. If you select a particular home page to be opened, Firefox will open the window with the specific URL of your home page(as seen in your attachment). You can try to select other option inside the "When Firefox starts:" drop down. Can you please try to reproduce this on the latest release version(42.0) and latest Nightly(45.0a1) and provide the results? When doing this, please test with a new clean Firefox profile or maybe even in safe mode(https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems). Some of this issues are related to third party installs. Also, is there a chance that the behavior described here is related to yours (bug 1194056)? Thanks, Paul.

Hi Paul, I've downloaded and tested with this: http://portableapps.com/apps/internet/firefox_portable The problem is still there. Try to reproduce this by switching 2 bookmarks: Click on the first bookmark Now, click on the second bookmark, and right after, press F6 (=Alt+D). [Make it like pressing together] Expected: F6 should SelectAll Problem: Sometimes you will see a blinking cursor on the right. As for bug 1194056: In my computer, after Enter on URL, the URL is locked and I can't typing in the URL. I could reproduce what he said, in Google Maps: Clicking Google maps bookmark > F6 > Typing in The text I typed in was replaced by other URL of Google Maps.

Hi reporter, I understand now what is your problem and I managed to reproduce it. When you open a bookmark or a link, the page will start to load. If you are fast enough to press F6 and type something in the address bar before the page loads, what you typed will remain in the address bar. If the link appears before you type anything, the cursor will move at the end of the link and your input will continue from the end of that link. Considering this I will mark this issue as New and assign a component to it. Thanks, Paul.

I think there's a duplicate of this around, it's intermittent anyway, likely order is not well handled in the code.
