In recent months the Mozilla team has not been very cohesive, something that seems to have touched the famous browser. In recent months, with the latest versions of Mozilla Firefox, the browser has introduced some serious security bugs as well as has incorporated interesting news like Pocket or as the inclusion of particular add-ons such as drm support or Mozilla Hello. But this circumstance is incompatible with Ubuntu as the release of the popular distribution is every six months. During this period the browser update is slow compared to other operating systems.
However there are other solutions to remedy this and get the latest version of Mozilla Firefox for our Ubuntu without having to wait for the Ubuntu update. As on many other occasions, the answer lies in the incorporation of a PPA repository. Using this PPA repository will make us always have the latest version of Mozilla Firefox on our Ubuntu.
All you have to do is open a terminal and type the following:
sudo add-apt-repository ppa:ubuntu-mozilla-security/ppa sudo apt-get update sudo apt-get upgrade
After these commands the system will start updating to the latest version of Mozilla Firefox and that will happen when a new stable version of Mozilla Firefox comes out.
Although many think that it is not very important and that with a beta repository works the same or better, this eventually creates many security holes and vulnerabilities in our system that can cause us to have serious problems, which is why it is interesting and important to have the latest version of Mozilla Firefox on our system and more if it is our default browser.
Personally it is one of the PPA repositories that I have in my Ubuntu and that I add after installation because unfortunately and until Ubuntu is rolling release, Mozilla Firefox update will always arrive late.
