You should know the newest web browser from Mozilla. Firefox 4 was downloaded about 45 million times since release in 22 March 2011. It has better support in HTML 5 and CSS 3.
Here is a screenshot of Firefox 4 in my Fedora.
In Fedora, you can easily upgrade to Firefox 4 by activate Remi Repository. If you didn’t activate it, you should follow this instruction. Here is some command to upgrade your firefox:
$ su -c "yum -y update firefox --enablerepo=remi"
Done. :)
