# Installing Firefox

In the past I struggled to get this to work, I'm going to try again.

Try installing

yum install  xorg-x11-server-Xorg xorg-x11-xauth xorg-x11-apps -y

If the repo is down try installing this way

wget http://mirror.centos.org/centos/7/updates/x86_64/Packages/xorg-x11-server-Xorg-1.20.4-16.el7_9.x86_64.rpm

mkdir /srv/tools
wget -O- "https://download.mozilla.org/?product=firefox-latest-ssl&os=linux64&lang=en-US" | tar -jx -C /srv/tools/

Create a symlink to a newly downloaded /srv/tools/firefox/firefox executable.

ln -s /srv/tools/firefox/firefox /usr/bin/firefox

Start the latest Firefox browser from GUI menu or by executing the firefox command.

firefox

If you get an error like this:

libgtk-3.so.0: cannot open shared object file: No such file or directory

Then you need to install GTK3

yum install gtk3-devel

# Run Firefox again
firefox

Getting this error?

Error: no DISPLAY environment variable specified

That means everything is working, now you just need to specify your local display for displaying the browser, for that you need to have X11 forwarding and an XServer. But no big deal, just two quick steps here
