How to update Mozilla Firefox web browser on 64-bit Ubuntu 12.04 LTS in a safe, secure, reliable, efficient and easiest way?

Solution 1:

You should find out what the latest packages available are, by first running:

sudo apt-get update

and then install the latest firefox:

sudo apt-get install firefox

Or you could install the latest "everything" with:

sudo apt-get upgrade

Ubuntu should have an updater (don't remember exact name) that checks for and asks you about installing (or optionally automatically installs) newer packages/software. Is yours not running or set to keep quiet?

And there's also apt-get dist-upgrade that upgrades Ubuntu to a newer release, but it's traditionally less reliable than a fresh install.

Solution 2:

1. Download the Latest Firefox version from here

2. Move this folder to /opt/

3. Open your terminal and type "./firefox"

4. Voila! Your New Firefox Version is running.

5. If you want to make this the default browser first go to /usr/bin and rename the previous version's Firefox executable to firefox-old and then move the new Firefox executable in /usr/bin

Solution 3:

Remove old version firefox from ubuntu using "softwarecenter", then again install firefox from "softwarecenter". It will automatically update firefox(only).
