Script to install traditional Firefox

[tenplus1]

I've always used the official Firefox .deb release for my Kubuntu desktop which seems to work really well and is optimized for Ubuntu already.

Recently I realized that Mozilla seems to have changed their compression methods from .bz2 to .xz - so the script did not work anymore.

I updated the script accordingly to version 2.1.4 and I deeply apologize for any inconvenience this bug may have caused for you!
