When I try to open eclipse, I get a small empty window.
I heard I have to change permissions. I tried that in eclipse and .eclipse, but it didn't work.
I heard I have to install a older xulrunner version.
apt-get cache search xulrunner finds xulrunner, but not the older versions
sudo apt-get install xulrunner=22.214.171.124 doesn't find a xulrunner 126.96.36.199 package to install (I guess it's the ubuntu2 or something that they add by the end, but I use kubuntu).
