You might need to set the environment variable MOZILLA_FIVE_HOME to the folder containing your Firefox or Mozilla installation. For example, setenv MOZILLA_FIVE_HOME /usr/lib/firefox-1.5.
To support the SWT browser widget, your Firefox browser must be dynamically linked, which means it was not downloaded from mozilla.org, but was compiled from source. This is typically the case when the Firefox comes as part of the distribution (that is, it is in a place such as /usr/lib/firefox).
One way to ensure that this is true is to see if it is the browser that is pointed at by /etc/gre.conf. The purpose of this gre.conf file is to point at an embeddable browser.
