I have use
OS X 10.6.8 for years and just recently did a fresh installation of Mavericks. One of the nicest aspects of OS X was the fact that after three years of use and installing tons of application, none of them, ever added any toolbar or extension to my firefox. As appose to windows that after couple of weeks, the browser looks like a circus.
Today during installing
uTorrent on Mavericks, I noticed that my firefox was reset and upon opening my home page changed to yahoo as well as my default search engine. Later I noticed that it has also added an extension to my browser.
Is this a flaw in the Apple new OS? Was it always there and I was just lucky in three years of using Snow Leopard? Is there some kind of security mechanism that I have to enable?
