Lightshot extension does not display itself.

I got mad at a website that wouldn't let me right click menu to save pictures, so I stubbornly saved them via less efficient means, in the process I picked up the Long Screenshot extension and this had an error shortly before or after I had an issue with Lightshot not appearing, other extensions did not appear either when I added them during this time period, but now these all appear with the exception of Lightshot, which gets deleted and reinstalled only to not appear, that of course being the problem, though I will also say that a right click menu not being there is like reaching onto my computer and pulling my finger away, sites that do that should be given the cold shoulder somehow, at least.
