I have started using Firefox instead of Safari as my main web browser. I have used Firefox off and on for quite a while, but couldn’t quite make the just, there was always something I liked better about Safari. This morning, while playin around with my bookmarks in Firefox I think I found the feature they will help me make the switch for good: Quick Searches. Quick Searches allow you to give a bookmark a keyword and format the URL properly to quickly search on external sites. For example, I just added a Quick Search bookmark for Wikipedia:

http://en.wikipedia.org/wiki/Special:Search?search=%s

They make Firefox for Mac, Windows and Linux. I suggest you make the switch, as well.
