Recently I wanted to update my firefox. First I uninstall it:

sudo apt-get remove firefox

Add the mozilla repository to sources.list https://launchpad.net/~ubuntu-mozilla-daily/+archive/ppa

Then install the firefox:

sudo apt-get install firefox

After installation, in command line, I type this:

firefox --version

Result: Mozilla Firefox 14.0.1 However, when run firefox, In Help > About Firefox, it is still showing version as 9.0.1 Am I missing anything ? I am using linux mint. Thanks,

Could it be you additionally installed FF9 manually, and it's in the PATH before this one? Check e.g. /usr/local/bin (comes before /usr/bin where the apt-installed one resides). –  Izzy Aug 2 '12 at 9:59
    
Hi. It shouldn't be manually installed. I remember it is bundled with the linux mint distributiobn –  Khue Vu Aug 4 '12 at 3:14
    
Sure it is. But that doesn't mean you could not have it installed manually (and sometimes there are good reasons to do so) -- so it was just a thought. Did you check the paths? Also a which firefox from the terminal might help to show which one is used. –  Izzy Aug 4 '12 at 17:23

As @Izzy said, try

which -a firefox

You will probably get two entries. You can check your $PATH by:

echo $PATH

You can modify it (among other ways) by editing/adding this line to your ~/.bashrc file:

PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:$PATH

Make sure to modify the line as needed for your directory structure. Again as Izzy said, make sure that the directory where the newer firefox binary is installed is before the one where the older version is.

Hi, thanks for your help. I have installed using deb package. So the bin is updated by the new one. Which -a firefox show one entry: /usr/bin/firefox only. Now I see the version reflected under Help is 14. I guess I need to restart my computer? –  Khue Vu Aug 15 '12 at 2:24
