Recently tried to upload pictures to Facebook using Firefox only to find it crashed on me the first time and errored on the second. I thought this was odd considering it uses a Java Applet which should be compatible with Sun’s Java.
Well I found that GCJ’s implementation of java caused the problem. To solve it just remove the following packages:
sudo apt-get remove gcj libgcj-common libgcj7-0
Then install sun’s version of Java
