Rated 5 out of 5 stars

I was really happy when I found this add on after updating to FF23 (Win8). I worked perfect. Just as I hoped.But since 2 days FF23 behaves as if I don't have this add on installed. I have no idea why: I didn't change anything, I didn't install other add ons, I didn't change any FF-settings. But all of a sudden searches in the URL bar get redirected to the search engine selected in the search bar although I have selected Google in the add on. I tried uninstalling the add on and reinstalling it, but it didn't change anything. So I'm totally clueless what happened.

Edit: 08-17-2013: The problem I mention above is the result of a conflict with the add on "TabMixPlus" set to open a new tab for every entry in the URL bar. If this is turned off (for addresses and searches) keyword search works like a charm! Thanks a lot to Mike!

This review is for a previous version of the add-on (1.0.5.1-signed). 

I'd love to figure out what's going on here. Can you contact me via email to try to debug - mozilla@kaply.com
