My Firefox Extensions

As in the previous entry “Goodbye Internet Explorer”, I strongly encouraged people to use Firefox for power surfing. By itself, Firefox is a lean and fast browser, and if you want it do more for you and remedy the situation that it lacks some of the functions that we’ve come to take for granted from Microsoft Internet Explorer, the add-on extensions maybe the best choice. They can do loads of tasks, from blocking pop-up ads to see the weather forecast—and even viewing a Web page as if it were in IE.

There are numerous extensions available and the question is where to start. Which extensions are worth downloading and installing? The answer is depending on your own needs. I just share my extensions for your reference here :

Tab Mix Plus 0.3.0.5 (strongly recommended!)

But I think you should’t install lots of extensions, since it will make your Firefox slower.
