Hey all, I'm running Safari 5.0.5 on OS X 10.6.8 - early 2011 MacBook Pro, 8GB RAM, SSD, etc. I upgraded to Safari 5.1 when it was released, but the whole experience was so horrible - slow performance, inactive tabs unilaterally refreshing themselves, etc - that I downgraded. So, a question: is 5.1.7 any better in this respect, or am I better off staying with 5.0.5? Clearly 5.0.5 is old and not getting security updates, and I'd prefer to be running an up-to-date browser, but not if the user experience is awful. Thoughts appreciated.
