Is there a way to add Duck Duck Go to the firefox search bar? I really like using keywords to launch searches (since I use VIMperator) but I can't seem to add arbitrary keywords to my knowledge.
To add it to the address bar, type about:config into the address bar, search for keyword.url and then change it to http://duckduckgo.com/?q= (or https://duckduckgo.com/?q= for SSL).
Add it to the search bar
In the search bar dropdown, click "Manage search engines"
Select DDG and set a keyword. I use "d".
Then, search using e.g. "d Hacker News"
:dialog searchanginesActually, it's much simpler than that: just right click on the search field and choose "Add a Keyword for this Search…".
I also use Vimperator, and have a DDG keyword search.
