Excellent but serious bug needs attention Bewertet mit 4 von 5 Sternen

Brilliant in it's simplicity. However, as mentioned by others but clarified here, there is a bug:
If you have multiple firefox windows open...
...and leave a value in the search box from a search...
... and then switch to another window and there do a new search...
...this will cause the search in the last window to activate, at whichever tab is open there and with whichever search engine that was passive in the search field.

PLEASE correct this in an otherwise most excellent add-on.
