Mozilla has just released Firefox 10. If you’re using an older version, now is the perfect time to upgrade. Firefox 10 is much faster than it’s predecessors, more secure, uses less memory and is more stable as well.
To upgrade just go to Help, About Firefox and click the Check for Update button. Firefox will download the update and you will be prompted to install the latest version.
If you don’t currently use Firefox and want to see what all the fanfare is about, you can read more (and download it) at the Mozilla Firefox website.
