Randomly one day I turn on my computer into Ubuntu and all of a sudden firefox (my browser of choice) keeps opening on its own, and if I let it will open 100+ instances of firefox so I had to uninstall it.

So then I try google chrome and it starts doing the same exact thing. So I uninstall that and try chromium and whadya know, same thing. Then I try opera and strangely enough, it works just fine.

But to my dismay I find opera to be a slow alternative, not very good and often unresponsive. So I really want to use firefox its my favourite browser. and this clearly seems to be a problem with the OS not the specific software. This problem makes my installation of Ubuntu virtually useless so if anyone has had this same problem or knows any sugestions it will be much appreciated thanks.

  • I can't say that I've experienced this issue with any Ubuntu PC I have installed and maintained. – mmstick Oct 21 '13 at 0:22

Try these once hope it would help you

  1. First completely remove firefox with it's configuration file using following commands:

    sudo apt-get autoremove firefox
    sudo apt-get --purge remove firefox
    
  2. Then remove the the ~/.mozilla directory by using this command:

    rm -r ~/.mozilla
    

    It will remove the configuration file/history of firefox for the current user

  3. Then re-install firefox using this:

    sudo apt-get -f install firefox
    

If it doesn't help then repeat the same procedure beginning from step 1, just replace the command in step 2 with this one:

sudo find / | grep -i firefox | sudo xargs rm -rf

Reply if something goes wrong..

Alternated Way

Run this command in terminal:

exo-preferred-applications

Then under Web Browser chose some other browser as you told Opera is working fine, select that. Restart your system and check if it happens again..
