Firefox 3.5 was released this week. Initially, I was ho-hum because I thought it was just a speed upgrade, and the only time I remember being impressed by browser speed was when Chrome came out last summer. But there are a few more interesting changes. Lifehacker provides an overview of more important Firefox 3.5 features. My favorite is pulling tabs out to new windows or merging them into existing windows. Reopening closed tabs also seems useful.
