"XPCOMMessageLoop" java.lang.​Unsatisfie​dLinkError

On a gentoo linux system I recieve this errormessage in matlab 2014a when running

> doc('plot')

I guess it is connected to this problem: Why do I receive JAVA errors when I execute 'doc'

Exception in thread "XPCOMMessageLoop" java.lang.UnsatisfiedLinkError: /usr/local/MATLAB/R2014a/sys/jxbrowser/glnxa64/xulrunner/xulrunner-linux-64/libxul.so: dlopen: cannot load any more object with static TLS

firefox-bin is installed, but it seems matlab can not find it. In the menu APPS/GET MORE APPS an error message tells:

which: no firefox in ...

In fact firefox is named firefox-bin if one uses firefox on a gentoo system. What is a proper solution to help matlab? Should matlab also search for firefox-bin?
