No I'm using Safari 4 - I can't upgrade to 5 because my data allowance is VERY limited, and I can't afford to download the installer.
I've tried numerous times to install ClickToFlash but it simply never installs - I keep getting the same error: "The installer could not write the receipt". I've tried restarting and installing, using an admin account, the terminal commands they suggest on their site - I don't know why, but it just won't work. Which is why I'm asking for a good alternative.
