Why do my Firefox quick searches not work anymore?
For anybody who’s interested, I’ve decided to give up on quick searches altogether, and on the basis of this comment change the keyword.URL value to “http://yubnub.org/parser/parse?command=”, meaning that anything I put into the address bar is executed as a YubNub enquiry, so I can do all sorts of searches and commands without having to bother with the whole keyword malarkey.
