Keeping Firefox + Java up-to-date on a Linux Mint

1) UPDATE FIREFOX

Copy the link of updated Firefox from ftp://ftp.mozilla.org/pub/firefox/releases/ (navigate through the right version / platform /  language)

$ cd /opt
$ sudo wget FIREFOX_DOWNLOAD_LINK
$ sudo tar xjf firefox-VERSION.tar.bz2
$ sudo mv firefox firefox-VERSION
$ sudo rm firefox-VERSION.tar.bz2
$ sudo ln -sf /opt/firefox-VERSION/firefox /usr/bin/firefox

(ref: # ln -sf TARGET LINK)


2) UPDATE JAVA

Copy the link of updated Java from http://www.java.com/en/download/manual.jsp list (Debian like users should choose "Linux" or "Linux x64")

$ sudo wget JAVA_DOWNLOAD_LINK
$ sudo mv DOWNLOAD_FILENAME java.tar.gz
$ sudo tar xzf java.tar.gz
$ sudo rm java.tar.gz

You should have a new /opt/jreVERSION

Now update the Java sym links:

$ sudo ln -sf /opt/jreVERSION/bin/java /etc/alternatives/java
$ sudo ln -sf /opt/jreVERSION/bin/java_vm /etc/alternatives/java_vm
$ sudo ln -sf /opt/jreVERSION/bin/javaws /etc/alternatives/javaws


3) UPDATE USER FIREFOX JAVA PLUGIN LINK

And last update the user Firefox Java plugin sym link:

$ ln -sf /opt/jreVERSION/lib/amd64/libnpjp2.so ~/.mozilla/plugins/libnpjp2.so
(if the platform is 64bits)

Restart Firefox and... voilá!
