CREAGB  I followed Stormchild advice and used command line to remove all instance of Cooliris. Had to use sudo to remove the Cooliris bundle. This is way too technical a requirement to uninstall an app. However, at the end everything returned to normal with no impact on my Safari settings.

This is actually fairly straight-forward and should be documented. I am a cookbook follower at this level, so this should be documented by someone who actually knows what they are doing. I can guarantee that it could be a script, so I do not understand why the "Uninstaller" script was not included.

CREAGB  Same problem as Stormchild. High-end iMac with plenty of memory. After installation it ran wonderfully for about 5 minutes, then massive destruction. Machine was completely unusable. No uninstaller. Like a trojan horse. Looks great. Deadly. I have lost two days so far trying to get this off of my machine. Nothing on developer site to suggest knowledge that this is a problem.

Symptom: Machine will be running fine, then almost instantly grind to a glacial pace. And I mean glacial. Ten minutes for a click to register. A hard restart is the only apparent way out. Simple uninstall of plugin does nothing and no documentation on how to back out.

Advice greatly appreciated.
