Hi there, since you're using a Linux distribution - you'll have to rely on your package manager for updates - your distro CentOS7 generally uses older packages than others for 'stability' purposes. And this distro is usually used for hosting servers, not desktop use.

It is my recommendation that you - download the tarball from the official download page, and read documentation on how to configure that or move to another distro - like Ubuntu, Mint, or Manjaro for the newest packages.

Hope this helps!

@bobamz,

As cOS7 is still officially supporting the older ESR (Extended Service/Support Release), you would use the same method as you (or your IT dept did to install anything newer (52.0.2+). If the event you have forgotten how (or your IT department did it initially) the process is below (assumes firefox-61.0.tar.bz2, which is the latest non-developer/beta release.

``` code: wget \ https://download-installer.cdn.mozilla.net/pub/firefox/releases/61.0/linux-x86_64/en-US/firefox-61.0.tar.bz2 \ ## Downloads the official Mozilla tarball

tar -C ~/.mozilla/firefox firefox-61.0.tar.bz2 ## Extracts the tarball into the finally location of ~/.mozilla/firefox

cd ~/.mozilla/firefox

sudo yum builddep firefox # su -c 'yum builddep firefox' would also work, this step recursively checks any new or updated dependencies and installs them.

./firefox &u # you can also simply symlink the ~/.mozilla/firefox/firefox bianry to /usr/local/bin/firefox if desired/allowed in your org.

```
