Location of the suggestions Rated 4 out of 5 stars

I've noticed something strange. When I type into the searchbar, which is on the right side of the URL bar, the suggestion showed up under URL bar instead of searchbar. I am using everything latest. How do I troubleshoot? Thanks

This review is for a previous version of the add-on (2.0.5.1-signed). 

This is a known issue on windows. I have submitted a bug for Firefox and am waiting to see what Mozilla is going to say.

Shortcut Ctrl-K Rated 4 out of 5 stars

Ctrl-K used to bring cursor to the searchbar. Now with the searchbar hidden (option hide when empty checked), it will bring me to the homepage of the search engine. Can I restore the old behavior? thanks

Sounds like a good idea. I have created a feature request for you.
