How to completely remove firefox so it won't update?

Question

I really don't like firefox, so the first thing I did after installation was install chromium as a browser and removed firefox via terminal using:

sudo apt-get remove --purge firefox

But every time update manager opens it lists language packs for firefox. I can uncheck the package, but it gets rather annoying.

Is there some lingering file somewhere that I need to purge as well?

Answer 1

Remove the firefox and all the associated language packs with this command

sudo apt-get --purge autoremove firefox

It should remove firefox and all language packs for it. The output in my computer is shown below:

anwar@edubuntu-lenovo:~$ sudo apt-get autoremove firefox
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following packages will be REMOVED:
  firefox firefox-globalmenu firefox-gnome-support 

Your output may vary depending on the packages you installed. The important thing is you should see the uninstallation of these packages

firefox firefox-globalmenu firefox-gnome-support

Using autoremove uninstall packages which was required by firefox but is not required now after removing it. Without autoremove those packages will be left on system.

See this apt-get manual page for more info.

Hope this helps.

Answer 2

In a terminal you can list firefox related packages.

dpkg --list | grep firefox

Uninstall the unwanted packages.
