Prave teraz som riesil presne tento problem s ColorZillou aj s Html Validatorom a kedze tu som odpoved nenasiel tak mi pomohol google. Postnem to aj sem ak by este niekto hladal ako ja.
V prvom rade zrejme treba nainstalovat libstdc++5
sudo apt-get install libstdc++5
Ja som to uz ale nainstalovane mal, takze nakoniec pomohlo toto:
1.) Uninstall Colorzilla in Firefox if you have it already there.
2.) Download the officially compiled binary tarball fo Firefox from:
http://www.mozilla.com/firefox/3.) Close Firefox
4.) Unpack the tarball to a temp place, e.g.
tar xzvf firefox-2.0.0.3.tar.gz -C /tmp/
5.) In the terminal window type the following command(and input your password afterwards):
sudo cp /tmp/firefox/libxpcom* /usr/lib/firefox/
6.) Run firefox and install Colorzilla again.
