Firefox could not initialize application security crash

Hi there I installed Ubuntu a few minutes ago (i'm very new on Ubuntu) and whenever I want to open Firefox I get an error which starts with "could not initialize application security ...".

Also when I try to restart Ubuntu it stops and I have to shut-down manually with the power button. During the shutdown there is a message

Killing all remaining processes --> fail

I will be glad if you can help me and thanks anyway

It sounds like you have a corrupted Firefox profile to deal with this problem you will need to run Firefox profile manager to do this open a terminal open the dash and type terminal
and enter this command at the prompt firefox -profilemanager like this

Terminal showing firefox -profilemanager command

and hit the Enter key

you should then see a dialogue like this

Firefox profile manager

you need to first delete the default profile then create a new profile

Hope this helps
