Why does Safari stop responding when trying to close certain pages?

[Legolas]

I switched to Safari because my laptop doesn't have much RAM and even when running low on RAM, Safari still operates smoothly unlike Chrome which starts to jitter and stutter. Only problem is that when i go on an online game, especially Ninja Kiwi's SAS Zombie Assault TD, and try to close the Tab it comes up with a confirmation message but then the browser just stops responding and I have to end it vis task manager to be able to do anything.

Yeah it happened sometime. There is no major issue, just delete cache, history, remove add-ons and also clear temp files.
Do these things your browser will not hanged again
