UPDATED: 1.0.2 adds support for POST search engines. You’ll have to install it manually if you have 1.0, since non approved add-ons don’t get updated automatically.
If you’ve been keeping up with the development of Firefox 23, you know that one of the big complaints is the change to keyword search. Starting with Firefox 23, searches in the URL bar will always use the search engine that is set in the search bar. So if you change your search bar to Wikipedia, and then do a search in the URL bar, it will use Wikipedia.
I’ve built an add-on that allows you to set the keyword search engine separately from the search bar. It can be any search engine you have installed. It’s called Keyword Search and it’s available from AMO.
Also note that this add-on includes DuckDuckGo as a recommended search engine. If you like the work I do, please consider trying it out and seeing if you like it.
