I clicked the Update to Firefox v19.0.2 last night on a Windows 7 laptop. Everything else on the laptop is the current version. I was logged in as a user that does not have admin access to install anything on the laptop. I was expecting the dialog box to pop up asking me to enter an admin password in order to allow changes to be made on the laptop. That dialog box never appeared, but the update successfully completed and Firefox shows the most recent version in About... How did you bypass the security on my laptop? I am concerned that if you can do it, so can everyone else out there. I thought I was protected from things being installed on my computer without my express permission..... How do I protect myself from such unauthorized changes in the future? Thank you for your help, Megan Everett
