Mac & Firefox user
I have just received the update as I am typing this and my opinion is that this can and will cause people to install safari by mistake but how many of those will actually use the application and how many will actually know its installed?
I have a mac and I run firefox as I prefer it to safari so I will not be installing it on windows.
I believe this practice is deceitful and could damage customers trust in apple, this is blatently an attempt to take advantage of users who do not inspect everything they download!
