One of the beauties of Firefox is its extensibility. The Mycroft project lists search plugins that use the small search box next to the browser address bar to search specific websites. All your favourites are there - Google, Amazon, Wikipedia, etc.
We have found these very useful, so have knocked together a few of our own. Click on the search title below to install the search plugin (in Firefox, you will need to check the "Allow web sites to install software" box in the "Tools | Web Features" menu.
I love this industry and industriousness.
Has anyone sorted Google PageRank for Firefox yet??
