One really important one for even non-dev users is that it isn't affected by DRM protections. Windows' screenshot tool nowadays blacks out any DRM content which makes screenshotting frames from a show, etc a royal pain in the ass, This is presumably because the tool can now also do video recording but either way it's very frustrating. The firefox tool doesn't have that issue.
