I have recently upgraded my imac g4 to OS 10.3.9 (panther) and yes I realise this is in 2012! basically all the web browsers are too old to use with pages like facebook or youtube and I pose the question, is it best to just upgrade to lion and pay the money -.- or is there a way that I can get a certain web browser than not only allows me to use modern websites but also to be downloaded onto such an old mac. HELP
