Everytime I open Firefox browser it tells me that it is not the default browser and I click on the button to make it the default. But it doesn't since the next I open Firefox it asks me again. Then clicking on Settings to try it there. nothing happens. Settings does not open. Is is possible that the anti-virus that i just installed is blocking it?
Picked up a refurbished Dell Lattitude today with Win 10 installed. Coming from Win 7 I spent several hours familiarizing myself with it. However, a few things seemed to just not work. Clicking on Settings, to change a few things like my default browser, does nothing. In fact clicking on a lot of things on the Windows desktop screen does absolutely nothing. Has the system been configured so that no one can change anything. It's like going into Best Buy and playing with some of the demos and they have a lot of things locked out.
