User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:61.0) Gecko/20100101 Firefox/61.0 Build ID: 20180704003137 Steps to reproduce: Enter any text in url bar (part of url or text search). Select any of results. Open new tab Enter any text in url bar Actual results: Entering any test in text (url or search text) in url bar does not show dropdown after first time it was shown. Popup is invisible (it's possible to click links). Same thing with suggests from stored credentials. You still can select suggested items by arrows. But list is invisible. Tested on FF 61 & 63. OS MacOS Mojave (latest build) Tried safe mode, private mode, clean install, removing profile. Expected results: Dropdown with autossuggests should be displayed.

Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:63.0) Gecko/20100101 Firefox/63.0 (20180718100918) I have tested this report on Windows 10 x64, Ubuntu 18.04 and OS X 10.14 (Mojave Beta) using the latest Nightly and Firefox release build. I was able to reproduce the mentioned behavior only on OS X 10.14. After the first suggestion is shown and selected, then the suggestions are no more displayed in a new tab. I would expect the drop-down with suggestions to be displayed. Please change if this is not the correct component.

Thanks for reporting. More information is in bug 1468053.
