I signed up for the FireFox account simply to respond to this question. I abhor plugins and add-ons, that appear without your permission or choice. I came out to FireFox to ensure that the Adobe Flash plugin was NOT activated on my FireFox browser. It isn't thank God. Adobe Flash is a menace!!! I had the Adobe Flash plugin disabled on Chrome and believe my Professional tech guy activated [it] by error. And, now Chrome is not allowing you to disable it, anymore. Nothing like Freedom of Choice, eh?? So, as soon as I find the Adobe Flash folder on my computer, I will DELETE that plug in. PERIOD. Thanks for allowing users to respond to their experiences re: add-ons, and plugins.
