How can I install Iceweasel in Ubuntu 15.04, and keep assured that it will not be replaced by Firefox in the future upgrades?

It is actually quite weird that sudo apt-get install iceweasel installs Firefox instead of Iceweasel on Ubuntu 15.04. I think that is not supposed to happen.

The reason is that Firefox started to use DRM - which I don't want.


Iceweasel web browser is a fork from Firefox for the purpose: backporting of security fixes to declared Debian stable version and no inclusion of trademarked Mozilla artwork.

Beyond that, they will be basically identical.

  • To get started, press Ctrl+Alt+T on your keyboard to open terminal. When it opens, run command below to add the PPA:

       sudo add-apt-repository ppa:dirk-computer42/c42-backport
  • Then update and install the browser:

       sudo apt-get update && sudo apt-get install iceweasel

Hope it will work.

  • it didn’t work, it's installing Firefox instead as well... :S – Paulo Silva Jun 5 '15 at 11:34
  • i needed to block firefox by editing /etc/apt/preferences [ Package: <nameofpackage> Pin: origin "" Pin-Priority: -1 ] (information from askubuntu.com/questions/75895/… ) and from ppa.launchpad.net/dirk-computer42/c42-backport/ubuntu/pool/main/… i needed to download libmozjs24d, xulrunner-24.0 and iceweasel, and install them one by one via gdebi, and on synaptic do menu:package/lockversion on each of them – Paulo Silva Jun 5 '15 at 12:04
  • i won't recommend this solution because it suggests version 24.3.0 which is out of date! – DJCrashdummy Jun 5 '15 at 13:02

it should be possible to add the repository of the Debian Mozilla team...

if nothing else is working you can maybe download and install the iceweasel-packages manually. BUT you have to update it every time yourself!
