Hello!      So this might be a very simple thing I've clearly skimmed over in the many times I've searched. Or perhaps I didn't enter the magic words into Google just that special way to get the help I desire...      I'm playing with Addon and Extentions weighing the pro's and con's of different Addons serving the same relative purpose. It's pretty irritating the method I am currently using, downloading an Addon and then going in, and then disable the one I downloaded to grab the next to avoid bad results that can arise from overlapping Addons working on the same functional area. I wanted to know if there was a means in which I could disable the automatic enabling of Addons when I add them from the default Firefox site?
