A while back I announced that I was now using Firefox rather than Microsoft's Internet Explorer. However, until this week I didn't realize you could add "extensions" to Firefox. Some of these are great.
I now have even more tabbed browsing options, can control which sites I allow to run JavaScript, and have added FoxyTunes, which allows me to have control of my music in my browser no need to tab back to the player just to pause or fast forward. There are many, many extensions available. I haven't finished reading through them yet.
