The one thing I always, always miss when I attempt to switch from Firefox to Safari is how Firefox automatically executes an I'm Feeling Lucky search from the address bar. It's an even better feature now that it searches my history/bookmarks first, allowing me to save the I'm Feeling Lucky step if I find a match first.<p>Safari mimics the live search of bookmarks/history in Safari 4, but what happens if I don't find a match there? I'm left with the search term in my address bar, and now I have to jump over to the Google Search field, <i>retype</i> my query, execute it, and then mouse down to the search results to get where I'm going.<p>Sigh.<p>Of course, if Firefox didn't regularly take up 15-20% of my CPU resources after having it open for 10 minutes I wouldn't be trying out new browsers every 3 months!
