jsf config error - MOZILLA_FIVE_HOME

Hello,

I am new to jsf.

I want to open a project.

Here are my steps

1-) File->New->Dynamic Web Project

2-) At opened form I select Configuration: JavaServer Faces v2.2 Project

3-) I click on Next button 2 times and reached to form Jsf Capabilities

4-) At articles, it says me to click on download button at the right of 1st textbox. Download starts but I got followğng error:

Unhandled event loop exception

No more handles [Unknown Mozilla path (MOZILLA_FIVE_HOME not set)]

I searched google and found an offer to set following

export MOZILLA_FIVE_HOME=/usr/lib/mozilla

I did it, restarted eclipse but same error exists!
