I upgraded to macOS Mojave 10.14 Beta Using Nightly with a new profile the AwesomeBar stops being awesome and providing me results after a few uses. I have to close and re-open the browser to get bookmarks and search suggestions again. Steps to reproduce: - open Firefox with new profile - type "apple" into search bar (result: search suggestions) - clear the search bar - type "mozilla" into search bar (result: search suggestions and bookmarks) - open a new tab - type "mozilla" into search bar (same result) - open a new tab - type "apple" (result: no type-ahead dropdown!, expected: same as before) - open a new tab - type "mozilla" (result: no type-ahead dropdown!, expected: same as before) See animated gif video demonstrating this: https://thumbs.gfycat.com/ChillyGiantClam-size_restricted.gif

On Release (61.01 64-bit) following the same steps, I can not observe the bar providing me _any_ results (above example in Nightly at least gave me two).

Thanks, indeed there is a known bug with the MacOS Beta, you duped this properly.
