I've been using that Firefox extensions for a long period of time now and I definitely recommend it. It has kept low the memory usage of the browser and on top of that it will speed up loading more and more the more tabs you have open. Thus I definitely recommend it! I may make a list of my favorite few and place them on here, or do one a week or something (but look how our plans go, they don't, especially with so many video games to play).
Will there be more craziness later in the week? we'll see!
