Life Hacker: "Last time we compiled our must-have Firefox extensions, it was two years (and one browser version) ago. Our new list keeps some, tosses others, and remains our go-to, Grandmaster list of the best Firefox add-ons.
All four of the editors you see posting here daily were asked to name the extensions they think have the most day-to-day value while also adding something new and unique to the open-source browser. It was reassuring to see that more than half of the extensions we featured last time 'round are still on the list, as they obviously kept their value. But four newcomers cropped up in the two years since then, and were innovative enough, or showed enough potential, to make it on our new compendium."
