Search Autocomplete от EcceNux

Using this add-on is rather simple. Just go to the address bar and type in `sa` and your search engine keyword (after space).

For example when you type in `sa en Some` in the address bar you will see a list of articles starting with "Some" from English Wikpedia.

By default there are two search engines available -- English and Polish Wikipedia [en].

Open settings of this add-on to view and manage your search engines. It's easiest to add another Wikipedia, but you should be able to add almost any search engine with autocomplete. More information is available in the readme: Custom search engines.
