Here's my new favourite Firefox feature.

1. Go to Technorati (or anywhere that has a search box)

2. Right-click in the search field and select 'Add a keyword for this search'

3. Tap in a name for the bookmark and a short keyword (I'll use 'tech' here)

4. Now, in the browser address bar type your keyword followed by something to search for, eg. 'tech computers'.
