I'm running OSx Yosemite 10.10.5 - after downloading and successfully updating Flash Player from the Adobe site using Firefox, I noticed that Safari (currently the system's default browser) opened and closed itself briefly. Is that behavior expected?
Also, while using Chrome earlier on, a website complained that my Flash Player was out of date and proceeded to download a .dmg file claiming to be an FP update without asking for confirmation. Are you aware of a way that such a file could unpack and install itself without admin privileges?
Try the forum for Flash Player.
Will do, thanks.
