On Linux systems any Eclipse-based project may fail to display apidoc-popups and other html-documentation, instead an exception like the following is shown:

[... shortened ... ]To fix this exception one has to install xulrunner:
On Debian systems install the package
xulrunner-1.9.1, i.e. xulrunner version 1.9.x (xulrunner 2.x did not work at the time this was written)xulrunner as installed by Debian (below
/usr/lib/xulrunner-1.9.1/) is automatically detected by Squish IDEFor other Linux distributions setting the MOZILLA_FIVE_HOME environment variable might be necessary; it should point to the location where xulrunner got installed to.
