Download3k search plugin for Firefox allows you to search and download Download3k's daily updated software applications database from within your Firefox browser. The results of your search are sorted by relevance and include both freeware and shareware programs. You also get a suggestion box for related searches and easy access to the most downloaded programs in the last 7 days through another box above. In order to install the plugin follow the instructions in the install screen or extract both files from the downloaded archive to your Mozilla Firefox "searchplugins" folder. After that restart your Firefox browser and select the new search engine from the search engines tab (usually located in the top right of your browser).
