I just bought a Macbook Air and want to use Firefox. Pardon my ignorance, I am not tech savvy, for I've a basic question. I started to install Firefox by clicking on the download button but the following message popped up: 

 I do not know what is right: to click on "cancel" or "allow" to proceed? I haven't a clue what is the right choice. I am not going to do anything beyond the basic, everyday stuff on my laptop, just want to make the smart choice to begin with, keepin' it simple. Thanks everyone!

Hello everyone, I just bought a Macbook Air and want to use Firefox. Pardon my ignorance, I am not tech savvy, for I've a basic question. I started to install Firefox by clicking on the download button but the following message popped up: "Do you want to allow downloads on 'www.mozilla.org'? You can change which websites can download files in website preferences." I do not know what is right: to click on "cancel" or "allow" to proceed? I haven't a clue what is the right choice. I am not going to do anything beyond the basic, everyday stuff on my laptop, just want to make the smart choice to begin with, keepin' it simple. Thanks everyone!
