Still lags while dragging words into search panel Noté 3 sur 5 étoiles

Searches in google instead of chosen search engine.

Yeap, only dragging into the bar. Typing manually goes as usual.
It happens not each time, but really frequently - i couldn't find the reason why. The browser just freezes with a screenshot like that
Default settings didn't help.
Error console screenshot. Don't know if it helps.

Cette critique est pour une version précédente du module (4.4.1-signed). 

Is there anything in the error console? If I understand correctly, this only happens when dragging words into the searchbar. Does it happen all the time?

Does it still happen if you change "extensions.quicksearchbar.setBackToDefault" in "about:config" to false?

Please respond to my e-mail. You can find it on the right side of the add-on's page here. It says "Support E-mail".
