I just installed x64 CentOS 5.4. The Firefox that's installed is something like version 3.0.18, current version is 3.6.something. I tried downloading the new version from their site, but when I open the "new" untarred files, it's still v3.0. How do I update to the newest version? Help > Check for Updates just says that FF is up to date.

Help!!!

Firefox 3.0.18 was released about 40 days ago.
3.0.xx is also the stable one on CentOS 5.4 .
I have tried using 3.5.x : There were some issues,
not quite stable.

CentOS 5.4 is not really about having the latest software,
but about stability and being rock solid.

Almost all the installed programs are 2006 versions,
but with the latest security updates.

If you want all installed packages to be the latest
versions, Fedora 12 is the choice.
.....

It doesn't matter that the version seems old.
The point is that Fedora or Centos apply any recent patches to their versions without updating the version number to the same as the mozilla version.

So the recent security scare has in fact been covered even though neither Centos or Fedora are offering Firefox 3.6.2
Fedora 12 is on Firefox 3.5.9-1 still.

Well the problem is that a lot of addons require a newer version. Should I use something aside from CentOS then?

Inside the folder you untarred, there is an executable file called Firefox. Just double-click on it to launch the new Firefox. You can put a shortcut on your desktop if you like. It will not replace FF3.0 that was installed through your package manager; you will have both versions side by side.

CentOS is a terrible choice if you want to have the latest applications. It is all about older applications that are thoroughly tested and known to be stable. (That being said, I personally have FF3.6 running in CentOS 5.4 using the method I described above. )

I did that, still opens 3.0.

If I want an OS that runs well like CentOS, and acts as a good development environment, what should I use? I don't want to buy RedHat.

IMHO learning how to download, untar, and execute the latest Firefox from the Mozilla website is a good first step towards becoming a developer.

If you want the latest apps by default, Fedora is a good choice.

Try installing this one
http://download.mozilla.org/?product...nux&lang=en-US

back up your current ~/.mozilla folder FIRST !

I'm untaring and executing everything correctly, not sure what the problem is.
