I switch a lot between different search enigines, such as IMDB, Mirrium-webster, Wikipedia, YACY ans so on, and with the prior versions when I chose a new Search Engine from the dropdown list it didn't instantly start a new search. I don;t want a new search commenced until I either press Enter or hit the Search Icon. How do I stop FF from doing this? The reason I don;t like FF doing this is because I don;t want the already searched for terms to be automatically used in a new search engine choice. THAT's the reason I choose to use another search engine previously.
