i have 1.33 GHz PowerPC G4, OS Tiger 10.4.11, my browser is Firefox 3.6.28 and i have Yahoo as my email. i know i can upgrade to Leopard, i was told. but i can ALSO DL TenFourFox for free, and it seems fine. i know there was an issue with HTLM5 and flash regarding YouTube, but is that such a problem now? would it still be a viable solution? thanks for all help, kurt
