You probably use a search engine to navigate the Internet. However, you might not know that Firefox allows you to use bookmarks and the “add keyword” feature to directly search any website that has an input field. This provides a modest privacy enhancement since you're cutting out the middleman (your default search engine) and it saves time to boot.
Let's take Wiktionary as an example, a multilingual dictionary.
Navigate to Wiktionary and right click Wiktionary's input field. A menu should pop up.
Click the “Add a Keyword for this Search…” option. Firefox should now
present you with a dialog box asking for the name of the bookmark, the
folder to save the bookmark in, and a keyword (I chose wkt).
If you were following along, you can now type in wkt (or whatever you
chose as a keyword) into Firefox's search bar followed by a word and
find its definition. If you don't have any ideas, figure out what the
difference between somnambulism and funambulism is, and why the two
probably wouldn't go well together.
You can search the ArchWiki, Wikipedia, or whatever you want in this
fashion. In addition, keywords work with ordinary bookmarks too (for
instance, awl is mapped to the “List of applications” ArchWiki
entry on my
computer). The main difference with regular bookmarks is that you don't
type anything except the keyword since you're no longer performing a query.
I prefer the bookmark method over adding a site as a search engine for two reasons:
